National Wildlife Federation Comments on Devils Lake outlet
Corps of Engineers Draft Environmental Impact Statement
Page 5
By 1981, the rising lake was creating problems at the City of
Devils Lakes new industrial park, which one city official
admitted privately was in an area that is too low to begin
with (Zaleski, 1981).
In the spring of 1982, at the same time the Ramsey County
Commission was petitioning to have Devils Lake declared a
disaster area because of flooding that was occurring as the lake
reached a level of 1427 feet (Associated Press, 1982), the Ramsey
County Water Management Board, which operates Channel
"A, had the control gates open to permit the discharge
of additional water into Devils Lake (Pearson, 1983).
A year later, in the spring of 1983, while the State was seeking
disaster assistance from the Corps for flooding problems around
Devils Lake, the Ramsey County Water Management Board, without
the required permit from the State Engineer, constructed a ditch
from Lake Irvine to drain up to another 6,000 acre-feet of water
into Devils Lake, and then a few months later approved a permit
to drain Morrison lake into Devils Lake (Pearson, 1985).
The attitude of drainage proponents in the face of the escalating
problems created by the rising level of Devils Lake was still
being expressed two years later in 1985 by Ramsey County Water
Resource Board chairman and Devils Lake Basin Advisory Committee
member Robert Garske:
Wetland drains are a round robin that profit
both farmers and businessmen, Garske said. Farmers can raise
wheat instead of ducks on drained wetlands, and businessmen
profit from more customers drawn to the Devils Lake fishery,
which runoff water supports by keeping the lake from getting too
salty and killing the fishery, he said.
Rather than trying to hold (water) back, we need to figure
out how to get more in, Garske said. (Buttz, 1985)
That attitude has not changed. At an August 26, 2000, public
meeting in Valley City, North Dakota, on the State of North
Dakotas proposed temporary emergency outlet
from Devils Lake, former North Dakota State Engineer David
Sprynczynatyk stated that his office would resume issuing permits
for wetland drainage in the Devils Lake Basin as soon as the
outlet is built.
At a June 22, 1983, public meeting held by the Corps on water
related problems in the Devils Lake Basin, the North Dakota
Chapter of The Wildlife Society reviewed the history of water
resource mismanagement in the Devils Lake Basin and recommended
that the Corps (1) place a ban on further wetland drainage in the
basin, (2) initiate a study of the impacts of current water
management practices on Devils Lake, (3) conduct a comprehensive
hydrologic investigation to identify the factors contributing to
flooding and other water resource problems in the basin, (4)
assume leadership in developing a comprehensive water resource
management program for the basin, and (5) reject the alternative
of an outlet to the Sheyenne River and require that water
management problems be resolved within the basin (Pearson, 1983).
However, nearly two decades later, the Corps still has done none
of these, but instead remains focused on the construction of an
outlet from Devils Lake to the Sheyenne River, while still not
having done the studies necessary to determine the causes of the
problem it purports to solve.
Wetlands and Wetland Drainage in the Devils Lake Basin
Although the DEIS acknowledges that wetland drainage in the
Devils Lake Basin is an issue that was raised in the scoping
process (DEIS Appendix C, p. C-102), it makes no attempt to
address the issue. In describing the Base Conditions/Affected
Environment, the only information related to wetlands provided in
the DEIS is:
Wildlife in the Devils Lake basin is closely associated
with water and wetlands. Shallow water wetland habitats are
clearly the most valuable habitat for waterfowl. Many wildlife
and waterfowl species utilize lakes in the Devils Lake chain and
surrounding habitats. Stump Lake has long been known as an
excellent staging and breeding area for waterfowl and shorebirds.
In 1905, President Theodore Roosevelt declared a portion of the
west bay of Stump Lake as a National Reservation, making it one
of the oldest refuges in the nation. (DEIS p. 2-14)
and in Appendix C, the DEIS states, regarding Base Condition
Upper Basin, that:
Wetland habitats of Devils Lake and its watershed can be
grouped into broad categories which provide several functions and
values unique to wetlands such as flood water storage, habitat
for wildlife, filtering of polluted water, and groundwater
recharge. Most of the wetlands in the basin can be classified as
palustrine, emergent, temporarily, seasonally and semipermanently
flooded wetlands. The upper basin chain of lakes can be described
as lacustrine. (DEIS Appendix C, p. C-20)
There is no discussion of the numbers and acreages of the
different types of wetlands originally in the Devils Lake Basin,
no discussion of the numbers, acreages and types of the wetlands
that have been drained and their flood water storage capacity,
and no discussion of the contribution of that drainage to the
rise in Devils Lake. In fact, the only substantive information on
wetlands and wetland drainage is in the Fish and Wildlife
Coordination Act Report, which is Appendix 2 to the DEIS. Here
the reader learns that the Corps initiated an evaluation of upper
basin storage in 1999 and that the evaluation was conducted by
WEST Consultants, Inc., of San Diego, California (DEIS Appendix
2, p. 10-1). The reader also learns here that the study by WEST
Consultants identified 200,000 acres of intact wetlands and
92,000 acres of drained wetlands, but the study covered only 68
percent of the Devils Lake Basin (DEIS Appendix 2, p. 10-2-3). In
addition, the digital evaluation model used by WEST Consultants
employed a 5-foot contour for 65 percent of the upper basin and a
10-foot contour for the remaining 35 percent that was studied,
resulting in a failure to identify many drained wetlands (DEIS
Appendix 2, p. 10-3). WEST Consultants also supplemented the
digital evaluation modeling with National Wetland Inventory maps
based on 1979 and 1983 photography (DEIS Appendix 2, p. 10-3),
but nearly 100,000 acres of wetlands already had been drained in
the Devils Lake Basin by 1975 (TPI Consultants, Inc., 1976), so
many of those also would have been missed.
As a result, its likely that a significant number of
drained depressions were never included in this study due to the
limitations of the DEM data, a fact that WEST acknowledges.
(DEIS Appendix 2, p. 10-3)
Because of the difficulty in accurately identifying drained
wetlands, a more reliable method is to compare the acreage of
remaining wetlands in the Devils Lake Basin with the original
wetland acreage in the basin. Hydric soils develop under
saturated or flooded conditions which support the growth of
hydrophytic vegetation and, therefore, are an indictor of
wetlands. Approximately 588,900 acres of hydric soils occur in
the Devils Lake Basin (U. S. Fish and Wildlife Service, 1997).
The Devils Lake Basin Advisory Committee, in a study authorized
by the North Dakota Legislative Assembly and prepared with the
assistance of the NDSWC and under the supervision of the
Governors Office, determined that 569,000 acres of wetlands
originally were present in the Devils Lake Basin, and that 98,000
acres of wetlands had been drained in the basin by 1975 (TPI
Consultants, Inc., 1976). Thus, it appears that from 569,000 to
589,000 acres of wetlands originally were present in the Devils
Lake Basin.
Ludden et al. (1983), using photogrammatic mapping of selected
areas of the basin, estimated that a total of 412,000 acres of
drained and undrained wetlands were present. The Fish and
Wildlife Service estimated in 1997 that there were 211,000 acres
of undrained and 189,000 acres of drained wetlands in the Devils
Lake Basin (U. S. Fish and Wildlife Service, 1997).
A July 14, 1998, letter from the North Dakota State Water
Commission to the St. Paul District of the U. S. Army Corps of
Engineers also reported that:
Approximately 211,000 acres of wetlands exist in the Devils
Lake basin including upper basin lakes, which comprise about
30,000 acres of the total.
The results of the study by WEST Consultants, Inc., are
consistent with these figures. WEST Consultants identified
201,990 acres of possibly intact existing wetlands in
the 68 percent of the Devils Lake Basin included in their study
(WEST Consultants, Inc., 2001).
West Consultants also identified 92,429 acres of possibly
drained wetlands in the 68 percent of the Devils Lake Basin
included in their study (WEST Consultants, Inc., 2001). However,
as noted above, the methods used in the WEST Consultants
study have been found to underestimate the acreage of drained
prairie wetlands by 50 percent (DEIS Appendix 2, p. 4-2), so the
92,429 acres of drained wetlands identified in the WEST study
likely reflect only half of 185,000 acres of drained wetlands in
the 68 percent of the Devils Lake Basin included in their study.
Therefore, it may be concluded that a minimum of 189,000 acres to
a maximum of 378,000 acres of wetlands have been drained in the
Devils Lake Basin.
Contribution of Wetland Drainage to the Rise of Devils Lake
Although wetland drainage obviously is not the sole cause of the
recent rise of Devils Lake, with inflows to the lake form 1993 to
1999 averaging 317,000 acre-feet (DEIS p. 1-5), the contribution
of wetland drainage to those inflows clearly warrants careful
evaluation.
Ludden et al. (1983) estimated the average depth of natural
wetlands in the Devils Lake Basin at 7.1 inches in 2-year
frequency runoffs, 11.8 inches in 10-year runoffs, 14.6 inches in
25-year runoffs, 15.7 inches in 50-year runoffs, and 18.5 inches
in 100-year runoffs, with maximum average depths of 20.9 inches.
The higher levels of precipitation and runoff in the Devils Lake
Basin from 1993 to 1999 were preceded by four years of severe
droughtcomparable to the Dust Bowl days of the
1930sfrom 1988 to 1992, so many of the wetland basins were
dry and at near maximum potential storage capacity at the time
the increased precipitation began in 1993. This would suggest,
therefore, that as much as 328,860 acre-feet of water entered
Devils Lake as a direct result of the lost storage capacity of
189,000 acres of drained wetlands in the basin. This is 2.6 times
the volume that could be removed from the lake by the proposed
Pelican Lake 300 cfs outlet operating at maximum capacity for
seven months from May through November. This does not include the
continued annual inflow reductions that would have occurred if
those wetlands had not be drained.
The U. S. Fish and Wildlife Service estimated the maximum storage
capacity of the 189,000 acres of wetlands it determined had been
drained in the Devils Lake Basin at 491,000 to 926,100 acre-feet
(U. S. Fish and Wildlife Service, 1997). This is 3.9 to 7.4 times
the volume that could be removed from the lake by the proposed
300 cfs outlet operating at maximum capacity for seven months,
and it also does not include the subsequent annual inflow
reductions to the lake that would have occurred if those wetlands
had not been drained.
WEST Consultants estimated the volume of the 92,429 acres of
possibly drained wetlands they identified in the 68
percent of the Devils Lake Basin included in their study at
132,729 acre-feet (WEST Consultants, Inc., 2001). However, as
noted above, the methods used by WEST to identify drained
wetlands likely resulted in the actual acreage of drained
wetlands being underestimated by 50 percent. Therefore, doubling
the volume of the 92,429 acres of possibly drained
wetlands identified in WESTs study results in a total of
265,458 acre-feet of lost initial storage capacity, and,
consequently, added inflows to Devils Lake when the 1988-1992
drought ended in 1993, as a direct result of wetland drainage.
This is 2.1 times the volume that could be removed from the lake
by the proposed outlet operating at maximum capacity for seven
months, and it is over three times the volume that would be
removed by the outlet in a typical year of operation. Of course,
this also does not include the subsequent reductions in annual
inflows that would have occurred if those wetlands had not been
drained.
It is evident from these data that the drainage of 189,000 acres
of wetlands in the Devils Lake Basinthe minimum
estimateresulted in 265,458 to 924,100 acre-feet of
additional water initially reaching Devils Lake when the
1988-1992 drought was succeeded by unusually high levels of
precipitation beginning in 1993. That is equivalent to an
additional 2 to 7 feet at the January 2002 lake elevation of
1447.1 feet and surface area of 132,000 acres, including Stump
Lake (DEIS p. 2-6), and it again does not include the subsequent
reduction in annual inflows that would have occurred if those
wetlands had not been drained.
The average annual reduction in runoff provided by the renewable
storage of existing, intact wetlands in the Devils Lake Basin
includes (1) the difference between average annual precipitation
(21 inches from 1993 to 1999) and evaporation (29 inches from
1993 to 1999) (WEST Consultants, Inc., 2001), which was 8 inches,
(2) percolation into the soil from wetland basins, which averages
7.2 inches, and (3) evapotranspiration from areas of emergent
vegetation in wetlands and vegetation at the perimeter, which
averages 25.32 inches (U. S. Fish and Wildlife Service, 1997).
However, because information is not available on the proportions
of wetland basins that are open water and the proportions that
have vegetation, and because the proportions vary with changes in
water elevations, for purposes of illustration, it will be
assumed that the combined evaporation and evapotranspiration from
intact wetland basins average 27 inches from 1993 to 1999.
Therefore, the average annual runoff reduction from existing,
intact wetlands is in the range of 1.1 feet, or 1.1 acre-feet per
acre.2 This means that the 211,000 acres of existing wetlands in
the Devils Lake Basin reduce annual runoff by 232,000 acre-feet
during wet periods like 1993-1999. This also means that, if they
were still intact, the 189,000 acres of drained wetlands in the
Devils Lake Basin could reduce average annual runoff by another
207,600 acre-feet. This continuing reduction in average annual
runoff if the 189,000 acres of wetlands had not been drained is
equivalent to 1.6 feet at the lakes January 2002 elevation
of 1447.1 feet, or 1.65 times the volume that could be removed
from the lake each year with the proposed Pelican Lake 300 cfs
outlet operating at maximum capacity.
Wetland Restoration and Upper Basin Storage
If all of the precipitation occurred as snow in the winter and
all of the runoff occurred as snowmelt in the spring with the
ground frozen, these figures would represent the annual net
renewable storage capacity and runoff reduction provided by
wetlands (particularly seasonal and temporary wetlands). However,
precipitation and runoff also occur at other times of the year,
and non-wetland and drained wetland soils also have the capacity
to store water and reduce runoff through percolation, evaporation
and evapotranspiration, so these must be subtracted to arrive at
the net increase in runoff reduction attributable to wetlands or
to the net reduction in runoff attainable through wetland
restoration.
WEST Consultants estimated the average additional annual runoff
reduction that could be achieved by restoring wetlands in the
Devils Lake Basin at 0.35 feet, or 4.2 inches, i.e., 0.35
acre-feet per acre of restored wetland (WEST Consultants, Inc.,
2001), and explained that:
This value primarily represents the difference between
storage and evaporation in restored depressions and the
percolation and evapotranspiration from the soil before
restoration. It does not represent the average evaporation from a
depression, which was approximately 20 or more inches per
year. (WEST Consultants, Inc., 2001)
However, the WEST Consultants report points out that:
The PRINET model did not include a soil moisture algorithm
beneath the [restored wetland] depressions. Instead, the
depressions were modeled as hard-bottom bowls.
Consequently, infiltration of water from a depression into the
soil and evapotranspiration from the soil in the dry portion of a
depression (when the depression was less than 100 percent full)
were not modeled. Therefore, the model could be underpredicting
the net total evaporation (free surface evaporation plus
evapotranspiration from the soil) in the depressions.
Since the net total evaporation from depressions was probably
underpredicted, the annual runoff reduction with depression
restoration could be underestimated. (WEST Consultants,
Inc., 2001)
The omissions and underpredictions result in a substantial
underestimation of runoff reduction resulting from wetland
restoration. First, including percolation from drained wetland
basins but excluding seepage from restored wetlands, which
averages 7.2 inches annually (U. S. Fish and Wildlife Service,
1997), underestimates average net annual runoff reduction of
restored wetlands by 0.6 foot. Second, including
evapotranspiration from drained wetland basins but not from
restored wetland, which averages 25.2 inches in prairie wetlands
(U. S. Fish and Wildlife Service, 1997), further reduces average
net annual runoff reduction of restored wetlands. Third, surface
evaporation in the Devils Lake Basin from 1993 to 1999 averaged
29 inches (WEST Consultants, Inc., 2001), or an additional 0.75
foot more than the 20 inches attributed to restored wetlands in
WESTs calculation of runoff reduction. Therefore, the 0.35
foot average annual runoff reduction for restored wetlands
calculated by WEST appears to underestimate the actual runoff
reduction by 0.6 foot of seepage and about 0.75 foot of combined
evaporation and evapotranspiration, or by a total of about1.35
feet. This is a 386 percent underestimation of potential runoff
reduction by restored wetlands.
In evaluating the potential for upper basin storage, WEST
Consultants determined that 79,762 acres, or 86 percent, of the
92,429 acres of drained wetlands they had identified in the 68
percent of the Devils Lake Basin included in their study were a
half foot or greater in depth (WEST Consultants, Inc., 2001).
Using 0.35 feet as the net average annual runoff reduction from
restored wetlands, WEST then calculated the average annual runoff
reduction for different climate sequences with restoration of 25
percent (19,472 acres) 50 percent (39,681 acres), 75 percent
(59,872 acres) and 100 percent (79,762 acres) of those drained
wetlands a half foot or greater in depth (WEST Consultants, Inc.,
2001). WEST calculated the capacity of 50 percent of the 79,762
acres of drained wetlands a half foot or greater in depth (39,681
acres) to be 63,608 acre-feet, and the average annual runoff
reduction with restoration to be 12,910 acre-feet under
stochastic climatic sequences and 15,642 acre-feet under the wet
climate sequence (WEST Consultants, Inc., 2001). With 100 percent
restoration, the 79,762 acres of drained wetlands a half foot or
greater in depth identified in the WEST study would have a
capacity of 127,835 acre-feet and would result in an average
annual runoff reduction of 23,841 acre feet under stochastic
climate sequences, or 31,193 acre-feet under the wet climatic
sequence (WEST Consultants, Inc., 2001).
The only upper basin storage alternative considered in the DEIS
is restoration of 50 percent of the 79,762 acres of drained
wetlands greater than a half foot in depth identified in the WEST
Consultants study:
For this analysis to determine effects on Devils Lake stage
effectiveness and cost effectiveness only 50 percent of the
possibly drained depressions by volume, with depths greater than
6 inches, were used. (DEIS p. 3-19)
In discussing the impacts of this level of upper basin storage,
the DEIS states:
Restoration of 50 percent by volume of the total possibly
drained depressional area greater than 6 inches in depth in the
upper basin would reduce the amount of fresh water entering
Devils Lake
Because of the small amount of annual inflow
reduction, ranging from 13,000 (stochastic) to 16,000 (wet
scenario) acre-feet, there would be little long-term effect on
water quality and the aquatic resource in Devils Lake (based on
restoration of 50 percent by volume of the total possibly drained
depressions greater than 6 inches in depth). (DEIS p. 5-32)
Consequently:
On the basis of analyses performed to date, upper basin
storage will not meet the project objectives as a stand-alone
project. (DEIS p. 4-9)
However, the assertion upon which this conclusion is based, i.e.,
that wetland restoration would result in only a small
amount of annual inflow reduction, ranging from 13,000
(stochastic) to 16,000 (wet scenario) acre-feet, seriously
underestimates, misrepresents and minimizes the potential for
wetland restoration in the upper basin to reduce flooding
problems at Devils Lake.
First, the 12,000 to 16,000 acre-feet annual inflow reduction
cited in the DEIS fails to consider the initial 63,608 acre-feet
of storage created by the restoration of 39,681 acres of drained
wetlands in the upper basin (WEST Consultants Inc., 2001).
Second, the 12,000 to 16,000 acre-feet annual runoff reduction
figures are based on the 0.35 foot figure from the WEST
Consultants report which, as discussed above, underestimates
seepage from restored wetlands by 0.6 foot and underestimates
evaporation from restored wetlands by 0.75 foot, for a total
underestimation of the annual runoff reduction from restored
wetlands of 1.35 feet. Therefore, the inflow reduction resulting
from the restoration of 39,681 acres of drained wetlands would be
63,608 acre feet initially, and then an average of 46,000
acre-feet under stochastic climate conditions to 62,000 acre-feet
under the wet future scenario annually thereafter.
However, because the WEST Consultants study also
underestimates the acreage of drained wetlands in the Devils Lake
Basin by 50 percent, the potential inflow reduction with
restoration of half of the 159,524 acres of drained wetlands over
a half foot in depth that likely are present in the basin
actually would be 92,000 acre feet (stochastic) to 112,00
acre-feet (wet future) annually. This is 1.15 percent of the
volume that would be removed by the proposed Pelican Lake 300 cfs
outlet in a typical operation year and 89 percent of the volume
that could be removed with the outlet operating at maximum
capacity under the wet future scenario, respectively.
It should also be noted that van der Kamp et al., (1999) report
that:
The long-term water level data presented in this paper show
conclusively that when the catchments of small prairie wetlands
are converted from cultivated land to undisturbed brome grass the
wetlands dried out and remained dry, even in years of heavy
precipitation.
Therefore, inflows to Devils Lake could be reduced even further
by planting the catchments of both existing and restored wetlands
to permanent grasses, rather than cultivating to the margins of
the wetlands.
The DEIS attempts further to diminish the feasibility of
alternatives involving wetland restoration in the upper Devils
Lake Basin by stating that:
About 75 percent of the land use (about 30,000 acres) in
the depressions is classified as cropland or grassland.
(DEIS p. 5-32)
Landowners in the upper basin
feel that drainage is
necessary in order to productively farm their land. They feel
that additional inflows from their drainage practices have had
little impact on increasing the lake level. (DEIS P. 4-9)
On the basis of previous attempts to voluntarily acquire
runoff storage areas in the upper basin, this plan will be
difficult and costly to implement. The value of payments to
acquire easements for storage areas, which are based on lost
productivity of the land, are likely to be contested by
landowners. This increases the administrative costs of
implementing this plan significantly. (DEIS p. 4-9)
Program administration and negotiations, included to
acquire land through condemnation (Minimum of $4,800 per
tract). (DEIS Appendix B, p. B-29)
Converting 30,000 to 40,000 acres of farmland to runoff
storage areas reduces the economic base of the local economy that
is already highly dependent on the agricultural sector. The
storage areas could be farmed in dry years. But, in those years
when they could not be farmed, the impact would be felt
throughout the local economy. (DEIS p. 4-9)
Annual costs for previous upper basin storage programs
ranged from $40 to $90 per acre per year. (DEIS Appendix B,
p. B-29)
This analysis assumes that the storage is in place when the
lake is above elevation 1440. Previous programs have varied from
an annual program to one with a 10-year contract. Therefore, it
is assumed that an expanded program could involve contract
lengths of any duration up to 10 years. Implementation of an
upper basin storage program would involve construction of outlet
structures, acquisition or leasing of land and development of an
operating plan for outlet structures when the lake recedes. On
the basis of these items, it was assumed that the implementation
of the storage would cost $1000 per acre. Therefore, the total
project costs are $39,681,000. (DEIS p. 3-20).
Consequently:
On the basis of the stochastic analysis, upper basin
storage is not cost effective. Net benefits result under the wet
future scenario. (DEIS p. 6-30)
Elsewhere, however, we find that:
In 1996, agriculture accounted for 48 percent of the
areas economy, followed by Federal Government outlays (38
percent), tourism (10 percent) and manufacturing (3 percent).
Tourism has been the fastest growing component of the areas
economic base, increasing from 3 percent in 1980 to 10 percent in
1996. Tourism is particularly important in Ramsey County, having
reached nearly two-thirds the importance of agriculture in 1996.
The tourism figures are understated because they account only for
the expenditures of travelers from out of state. (DEIS p.
2-16)
The per-acre market value of land and buildings is also
similar: Ramsey $391, Benson $320, Nelson $476. (DEIS p.
5-19)
and:
many candidate wetlands in the High and Severe
[salinization] hazard classes may be good candidates for
restoration because they may no longer represent productive
cropland. Many such wetlands are now unsuited or marginal for
agriculture due to drainage-related salinity problems. Placing
restored saline wetlands and their surrounding buffer zones into
a conservation reserve program may be an attractive option to
farmers whose land is not producing efficiently because of
existing, drainage-related salinity problems. (DEIS
Appendix C, p. C-113)
Costs for these outlet structures
could vary from $0
up to $100,000 per site. (DEIS Appendix B, p. B-29)
Costs for easements or leases could vary widely since some
lands may be more valuable agricultural areas than others may
(ranging from 10 to 70% of fee title). (DEIS Appendix B, p.
B-29)
Approximately 200,000 acres of land is currently under the
CRP program in the basin. (DEIS Appendix C, p. C-17)
The Corps failure to consider wetland restoration
objectively and forthrightly in discussing the upper basin
storage alternative is reflected in the statement that:
Upper basin storage consists of storing water in
depressions in the upper basin. This alternative would result in
the conversion of agricultural lands to intermittent or permanent
wetland storage areas. (DEIS p. 6-30)
Clearly, the Corps does not understand, or does not want to
recognize, that wetland restoration involves converting wetlands
that have been drained for agricultural production back to
wetlands, rather than converting what were originally
agricultural lands to wetlands.
It is apparent that restoring 40,000 to 80,000 acres of farmed
wetlandsequivalent to 20 to 40 percent of the CRP acreage
or 2.6 to 5.2 percent of the 1,562,000 acres of cropland in the
basinwould not have a negative impact and could actually
have a positive impact on the local economy and could be an
attractive alternative for many landowners with marginally
productive drained wetlands or drained wetlands that still cannot
be farmed in wet years. It also is evident that the $1000 per
acre figure assumed in the DEIS for wetland
restoration represents a significantly inflated
estimateperhaps by two to five timesof the actual
costs of a properly managed wetland restoration program.
Consequently, by minimizing the benefits of wetland restoration
by several fold while exaggerating the costs by several fold, the
DEIS seriously underestimates, and thereby dismisses, the
feasibility of the upper basin storage alternative.
The failure of the DEIS to provide an accurate, objective and
realistic analysis of upper basin storage involving wetland
restoration and other land use practices to reduce inflows to the
lake renders the discussion of alternatives to the proposed
action, and therefore the DEIS itself, inadequate on their face.
Continuing Wetland Drainage in the Devils Lake Basin
Because continued drainage of the remaining 211,000 acres of
wetlands in the Devils Lake Basin would eliminate the water
storage and runoff reduction capacity of those wetlands and
exacerbate the problems caused by the high water at Devils Lake,
the U. S. Fish and Wildlife Service points out:
Accelerated wetland drainage in the upper basin as a result
of the outlet. The Service is concerned about the accelerated
loss of wetland habitat in the upper basin as a result of this
project. A private drainage survey conducted from 1965 to 1980
documented a 2.5 percent drainage rate of wetlands per year in
the Devils Lake basin. The Service believes that the pressure to
drain remaining unprotected wetlands for agricultural and other
purposes has not diminished over time. Within the basin, there is
continuing legal action by lower basin landowners who claim that
they have been adversely affected by the rise of Devils Lake, due
in part to decades o[f] wetland drainage by upper basin
landowners. In the recent wet cycle, the practice of wetland
drainage, including pumping, has shown itself to be a
contributing factor in the rise of the lake. The Service is
concerned that the construction of an outlet, without control on
additional inflow to the lake from drainage, will provide the
supporters of wetland drainage a way to export water out of the
basin. (DEIS Appendix 2, p. 11-20)
Therefore, the Service recommended:
Moratorium on new wetland drainage and pumping within the
basin for the life of the project. The Service recommends that
the Corps coordinate with the State to insure that any plans to
remove water from the landscape and place it into the lake
through wetland drainage be postponed during the life of the
project to avoid the need to move additional water downstream.
Taking precautions to prevent further aggravating factors, such
as wetland drainage and pumping from increasing lake levels is
consistent with the goal of the outlet to reduce lake levels and
prevent a natural overflow of Devils Lake to the Sheyenne
River. (DEIS Appendix 2, p. 14-2)
As noted above, at a meeting in Valley City, North Dakota, on
August 26, 2000, former North Dakota State Engineer David
Sprynczynatyk stated that his office would resume authorizing
wetland drainage in the Devils Lake Basin as soon as an outlet to
the Sheyenne River is built. However, the Corps summarily
dismisses the Fish and Wildlife Services recommendation
with the perfunctory statement that:
The Corps concurs that controls on future wetland drainage
in the upper basin would improve the effectiveness of other
features. The decision to place a moratorium on future drainage
is under the control of the State. (Emphasis added)
Thus, the Corps agrees that future wetland drainage in the Devils
Lake Basin would reduce the effectiveness of its proposed $125
million Pelican Lake 300 cfs outlet, but it leaves control of
future wetland drainage to the very agency which already had
announced publicly two years ago that it will resume authorizing
wetland drainage as soon as the outlet is built!
WEST Consultants estimated that the 201,990 acres of remaining
wetlands identified in their study have a capacity of 481,604
acre-feet (WEST Consultants, Inc., 2001), and draining those
wetlands could contribute up to 481,000 acre feet of water to
Devils Lake.3 This is equivalent to 3.6 feet at the lakes
January 2002 elevation of 1447.1 feet, and it is 3.8 times as
much water as the proposed Pelican Lake 300 cfs outlet could
remove operating at maximum capacity from May through November.
Drainage of the 201,990 acres of remaining wetlands would also
result in an additional 272,000 acre-feet of inflows to Devils
Lake annually, which is more than two times the volume that could
be removed by the proposed Pelican Lake 300 cfs outlet operating
at maximum capacity.
It is clear, therefore, that before expending any further public
revenues on the proposed $125 million Pelican Lake 300 cfs outlet
or other structural measures to deal with problems caused by the
high water levels at Devils Lake, the Corps has a fiduciary duty
to implement and enforce an effective program to prevent further
wetland drainage in the Devils Lake Basin in order to protect the
Federal Governments investment in those measures. That
drainage prevention program and its enforcement provisions should
be discussed in detail in a revised DEIS.
