Re: Klamath Project:
Revised Incidental Take Statement
Dear Mr. McInnis:
By letter dated April 1, 2004, NOAA Fisheries transmitted to the
Klamath Basin Area Office of the Bureau of Reclamation a revised
incidental take statement (ITS) for NOAA Fisheries’ May 31, 2002
biological opinion (BO) regarding impacts of the Klamath Project on coho
salmon. This letter provides the comments and objections of the Klamath
Water Users Association (Association) to the revised ITS.
As you know, the Association and its members are vitally interested
in the application of the Endangered Species Act (ESA) to the Klamath
Project. We have sought at every opportunity to be heard. We have made
known our desire to be involved and provide input to the agencies and
have repeatedly asked for meaningful consideration of our views.
Against this background, the appearance of the revised ITS is
startling. We had no notice that it was under preparation. We were not
afforded opportunity to provide any input. We were not furnished with a
draft ITS for comment. Our community has in the past suffered from
unjustified regulation that ignored our comments and concerns, and we
had hoped this could not occur again. However, the ITS simply appeared,
sending the message that Reclamation and the affected communities will
live with what NOAA Fisheries dictates, without dialogue. This is
unacceptable.
Notwithstanding NOAA Fisheries’ avoidance of the Association’s
concerns or interests, we are here providing our comments and objections
to the revised ITS. As described below, the revised ITS is fatally
flawed from a legal perspective, and biased and arbitrary from a
technical perspective. A number of shortcomings perpetuate those in the
2002 BO. These deficiencies should be cured in a new ITS and any future
BO.
STRUCTURAL AND LEGAL DEFECTS
In general, the ITS identifies a "surrogate" method for defining the
amount or extent of incidental take. The surrogate is the "maintenance
of certain flow-related habitat conditions." If these flows are
maintained, incidental take is deemed to be "within the acceptable
range." If they are not, the assumed "take" is assumed to be
unacceptable. In addition to identifying these flow conditions, the ITS
prescribes specific " Reasonable and Prudent Measures" (RPMs) to
minimize take resulting from the action, and "terms and conditions" to
implement the RPMs.
Failure to Identify Take
The ITS assumes "take" is acceptable if certain flow conditions are
maintained. It utterly fails to explain how take is determined. In turn,
this failure implicates two major deficiencies.
First, the ITS avoids any genuine determination of take at all.
Nowhere is there any articulation of whether or how some incremental
change in flow (say, from 1200 to 900 cfs) supports a conclusion that
take or increased take occurs or is likely. This point is reinforced in
our discussion of technical issues, below.
Second, there is no discussion or analysis that explains what flow
condition is being compared to some other condition in order to
determine whether and what take may occur. Stated another way, there is
no identified baseline for the determination of take.
The ITS assumes some level of take from the proposed action and RPA.
Necessarily, in the absence of the "action," there would be no take
resulting from the action. To determine take would require comparison of
"no action" to the action. The ITS does not, however, make such a
comparison or even try to do so. For example, the ITS refers to reduced
rearing habitat, elevated water temperature, and increased smolt run
timing. The obvious question is: "reduced," "elevated," or "increased"
as compared to what? There is no answer to be found in the ITS.
The Association has repeatedly pointed to this type of deficiency in
NOAA Fisheries’ documents and the Association has repeatedly been
ignored. In our May 23, 2002 comments on the April 25, 2002 draft BO for
operation of the Klamath Project, we emphasized the need for a coherent
logic in determining the effects of an action. While focusing primarily
on determinations for purposes of section 7(a)(2) of the ESA, the
discussion is equally applicable to determining the take associated with
an action. The determination of effects requires an evaluation of the
action against an environmental baseline. 50 C.F.R. § 402.02. So, too,
does the determination of take require an evaluation of the action
against a baseline, or no-take, condition.
In its February 25, 2002 biological assessment (BA), Reclamation
described the proposed action as including diversion of water to direct
use, diversion of water to storage, and use of previously stored water.
It supplemented the action with a water bank to ensure certain flows.
NOAA Fisheries has never defined the action, and has avoided any
approach that actually seeks to determine the effects of the action.
Notably, Reclamation’s BA properly concludes that use of
previously-stored water has no effect on the species because it results
in no change as compared to the environmental baseline. NOAA Fisheries
has ignored this issue altogether. It continues to regard the ESA as a
vehicle to mandate flows, which it manifestly is not. In the end, the
ITS results in an attempt to prescribe flow conditions. This is far
beyond the authority to impose RPMs and terms and conditions, as
described below.
Unlawful Mandates
The ITS contains RPMs and terms and conditions to implement the RPMs.
The majority of such provisions are unlawful and outside NOAA Fisheries’
authority, as described below.
First, RPMs and terms and conditions must be limited to minimizing
the incidental take of the action (and any RPA). 16 U.S.C.
§ 1536(b)(4)(B), (C)(ii); 50 C.F.R. § 402.14. Numerous provisions of the
ITS relate to reducing purported take of activities that have nothing to
do with the operation of the Klamath Project. These include, but are not
necessarily limited to, provisions requiring augmentation of water
supplies and provisions related to diversions outside the Klamath
Project.
Second, obviously, there must actually be take to be minimized
by the RPMs and terms and conditions. As described above, there is no
defensible analytical framework in the ITS even for determining whether
or how take occurs under the action. Similarly, there is no basis to
conclude that discharge from the Straits Drain causes take or that
recycling of Straits Drain water would minimize take. See also
Arizona Cattle Growers Association v. Fish and Wildlife Service,
273 F.3d 1229, 1244, 1246 (9th Cir. 2001).
Third, even if they were otherwise proper, the RPMs and terms and
conditions exceed the authority provided in the ESA. RPMs, and terms and
conditions, "cannot alter the basic design, location, scope, duration,
or timing of the action, and may involve only minor changes." 50 C.F.R.
§ 402.14(i)(2). The "surrogate" for take (flow levels) is, in effect and
in reality, specified as a (binding) RPM or term and condition. It
fundamentally changes the action and is improper.
The terms and conditions actually labeled as terms and conditions
additionally exceed the limitations on the scope of RPMs and terms and
conditions. They do not involve "minor changes" in the action. Rather,
they impermissibly require the undertaking of entirely new activities.
LACK OF OBJECTIVITY AND TECHNICAL DEFECTS
In addition to the fundamental, fatal defects described above, the
ITS is laden with speculation and ambiguity, and lacks objectivity. It
is particularly illustrative to review the sources cited in the ITS, and
consider the sources not cited. We find extensive citation
to the draft "Hardy Phase II" Report (even though NOAA Fisheries
acknowledges this draft Report is undergoing revision) and a draft
California Department of Fish and Game Report. Tellingly there is no
reference to the "draft" undepleted flow study completed by the Bureau
of Reclamation. Nor is there reference to any number of reports or
studies that lead to different conclusions than the ITS. Shockingly,
there is no reference whatever to the final report of the National
Research Council of the National Academies (NRC Committee Report). The
NRC Committee Report, of course, was commissioned by the Departments of
Interior and Commerce. Its dismissal by NOAA Fisheries clearly signals
that the Report does not serve the policy objectives of the authors of
the ITS. The Association strenuously objects to this omission.
Below, we address specific subjects discussed in the ITS.
Reduced Rearing Habitat
The ITS states that a "reduction" in spring mainstem flows during the
months of March through June is expected to result in take of
young-of-the-year and yearling coho that are attempting to rear in the
mainstem Klamath River by decreasing the area of edgewater habitat
downstream of Iron Gate Dam (IGD). Consistent with our previous comments
provided to NOAA Fisheries on the topic, the NRC Committee stated in its
April 30th letter to Dr. Hogarth:
In general, the committee was concerned about the paucity of
evidence for the assertion in the biological opinion that the main
stem is an important rearing area for coho salmon.
and
Also, given the absolute scarcity of coho, it seemed unlikely to
the committee that the coho is saturating its available main-stem
habitat, even without augmentation of main-stem flow.
and
Finally, the committee did not find convincing evidence in the
biological opinion or in other documents that the main stem is a
significant rearing area for coho, even though it seems likely that
the main stem is an important rearing area for other anadromous
species.
In addition, the NRC Committee, in its final October 2003 report,
concludes "rearing of coho in the Klamath main stem is much less
important than rearing of coho in tributaries, which are the preferred
rearing habitat of coho."
Despite this information, the ITS (like the 2002 BO) continues to
speculate on the potential benefits to coho fry derived from edge
habitat in the Klamath River. There are no data to suggest that edge
habitat in the mainstem Klamath River is limiting the coho population.
In fact, if NOAA Fisheries had properly used the results of the modeling
exercise from the draft Hardy Phase II report, it would have shown that
existing Klamath River edge habitat is more than adequate for coho fry
in the mainstem. Additionally, based on information presented to the NRC
Committee during its March 2003 meeting in Medford, Oregon, the fishery
agencies have been assuming that chinook salmon fry can serve as a
surrogate for coho fry for modeling rearing habitat. Even if this
assumption was true, fry have much more habitat available in river
channels than that surmised by the BO. Mr. David Vogel (Natural Resource
Scientists, Inc.) provided this information to the NRC committee (and
NOAA Fisheries staff in attendance) at the Medford meeting based on his
extensive research and observations on salmon fry rearing in
mainstem river channels. He also showed the committee underwater video
footage demonstrating this fact.
As we have described in extensive detail in our previous comments to
NOAA Fisheries, the available information demonstrates that the
mainstem Klamath River in the river reach most affected by the Klamath
Project is not a principal factor limiting coho populations. Here
again, NOAA Fisheries has ignored this highly relevant information
and the NRC Committee’s response and, instead, suggests that
somehow, through unknown mechanisms, coho fry rearing habitat is
limiting the populations.
The ITS and BO that precedes it do not describe why maximizing coho
fry rearing habitat in the mainstem immediately downstream of IGD is
necessary. Using a hypothetical example, if one coho fry already has
1000 sq. ft. of habitat available and needs only 100 sq. ft. to survive
well, why does the fry need 2000 sq. ft. of habitat? Additionally, the
BO and ITS do not describe if (and if so, how) coho fry rearing habitat
in the mainstem reach most affected by Iron Gate Dam is limiting the
SONCC ESU. This is particularly relevant when one considers the vast
proportions of coho spawners, fry, juveniles, and their habitats that
are found elsewhere in the Klamath Basin and in other drainages (i.e.,
coastal streams between Cape Blanco, Oregon, and Punta Gorda,
California).
The ITS states that, between March and June, "shallow
edgewater and side-channel habitat provides young fish refuge from
excessive flow velocities, while overhanging riparian vegetation
protects juveniles from predation and contributes insect prey favored by
young salmonids." Many of the desirable characteristics for juvenile
salmonid rearing habitat are also desirable areas for predatory fish.
The ITS falsely presumes that young coho can only escape predation
through the provision of edge habitat. In fact, coho rearing areas are
available in many other areas of the mainstem and in the tributaries.
Elevated Water Temperatures
While the ITS notes that "the complex interaction between juvenile
coho survival and mainstem Klamath River temperatures is not fully
understood at this time", it nevertheless concludes that "flow
releases lower than those outlined within the RPA are not likely to
offer the same level of relief and could potentially result in increased
coho take." The ITS assumption that Iron Gate flows—particularly in
"critical summer months"—will impart positive temperature benefits to
coho salmon is completely speculative.
There is no evidence to indicate that increasing upper Klamath
reservoir releases during late summer or early fall would benefit
salmon. In fact, because of a variety of meteorological, physical, and
biological reasons, artificially increasing flows at that time would
probably be harmful. This is due to the fact that IGD discharges are
unsuitably warm for salmon through early September. The gradual
declining temperatures in the Klamath River downstream of IGD during the
fall are primarily attributable to normal seasonal declines in ambient
air temperatures, not river flow. The NRC Committee found that higher
summer flows from IGD increase minimum temperatures and may increase the
temperature of cold water refuge areas in the mainstem. The NRC
Committee also discussed strategies to reduce the temperature of IGD
releases and concluded:
…information from thermal modeling shows that introduction of
cool water would provide benefits only for a relatively short
distance downstream of (Iron Gate Dam), given that summer thermal
loading of the mainstem Klamath River is high and that accretion of
flows from tributaries consists primarily of warm water in summer.
Vogel and Marine (1994) and Vogel (2002) recommended that any
increased flows from IGD, pulsed or otherwise, to benefit adult salmon
should occur during late September or early October to coincide with
normal seasonal declines in air temperatures and concomitant cooler
river flows.
Increased Smolt Run Timing
The ITS assumes a spring flow/coho smolt survival relationship. NOAA
Fisheries has failed to acknowledge that there are no data to
demonstrate that this factor is limiting the production of coho in the
Klamath River. The assumption cited in the NOAA Fisheries BO was largely
derived from studies of salmon migrating through the large Columbia
River reservoirs, not the free-flowing Klamath River. Additionally, the
BO suggested that the draft Hardy Phase II report supports the NOAA
Fisheries premise on this topic. This assumption is incorrect because
the draft Hardy Phase II report used a computer modeling exercise to
predict theoretical habitats such as rearing and spawning, not
outmigration habitat or outmigration survival.
The NRC Committee has also spoken on this matter. The April 30, 2002
letter from the NRC Committee to NOAA Fisheries states:
As the interim report pointed out, if low spring flows were
limiting survival in dry years, then year classes from wet years
should have been stronger than those from dry years, but no evidence
was presented that they were. The committee recognized that while
smolts theoretically might benefit from higher spring flows that
could reduce passage time and exposure to predators, there was no
evidence from existing information to support this conjecture. The
committee was aware of and took into account the benefits of
suitable habitat for migrating fish. As with the case of judgments
about the flows in the spring months, however, the committee
concluded that a convincing case had not been made that marginal
increase in habitat would lead to marginal increases in growth or
survival, especially in view of this species’ scarcity, which
suggest failure of the species to saturate its main-stem habitat
under current conditions.
In its final October 2002 report, the NRC Committee noted:
"…mainstem flow may directly affect the coho population at the time of
downstream migration of smolts…there is some probability of benefit for
the smolts to be derived from minimum flows at the time of smolt
migration, as expressed in the NOAA Fisheries biological opinion of 2002."
The NRC Committee’s statements are consistent with our previous
technical comments provided to NOAA Fisheries. Here again, NOAA
Fisheries has ignored this highly relevant information and
the NAS Committee’s response. Instead, NOAA Fisheries suggests that
somehow, through unknown and un-quantifiable mechanisms, spring flows
are limiting coho populations.
The ITS discusses "transit" between IGD and Seiad Valley. It does
not, however, discuss whether there are even significant numbers of
listed coho smolts in this reach. Nor does it recognize the annual
variability in flows that will occur with or without any RPA.
The NRC Committee urged "adaptive management principles could be
applied to this issue". Using increased smolt run timing as a
justification for using flow variability as surrogate indicator of
potential take provides yet another opportunity for advocates of high
main stem flows to allege a potential ESA violation in times of low
flows at Iron Gate Dam. Increasing the rigidity for minimum flows at
Iron Gate Dam is not consistent with an adaptive management philosophy.
Again—we reiterate what the NRC Committee stated in its October 2003
report:
"...it is unlikely that increased summer flows would benefit
juvenile coho salmon."
Juvenile Stranding
NOAA Fisheries admits that estimating potential coho salmon stranding
and the resultant incidental take is "difficult". Nevertheless, the ITS
concludes that juvenile coho stranding will increase if IGD flows are
ramped down faster than those outlined within the RPA. According to the
ITS, yearling and fry coho salmon "could" become stranded in isolated
pools and side channels as flows are reduced below IGD. As is apparent
throughout the ITS document—and the BO upon which it is based—NOAA
Fisheries fails to separate facts from assumptions. We are concerned
about the widespread use of vague or generalized statements like these
in the ITS. Accurate identification, description, and analysis are
required to justify these statements.
NOAA Fisheries must clearly justify that they have clear evidence to
support that Klamath Project operations have directly resulted in fish
stranding below Iron Gate Dam. In May 2002 media accounts, for example,
environmentalists quickly blamed fish strandings below IGD on water
diversions to farmers. U.S. Interior Department officials ultimately
disputed the reports as erroneous, pointing to an unusual snow/rainstorm
that they say contributed to the river’s sudden rise and descent.
Delayed Adult Passage
The ITS claims that "low IGD flows during the mid-August through
October period may result in take of adult coho salmon through
delayed upstream migration. Any delay in the natural migration rate
could leave adult coho more susceptible to estuarine predators…while
increasing the risk of mortality associated with density-dependent
diseases… ." (emphasis added). The final NRC Committee report,
however, questioned the degree of influence of the Klamath Project on
the estuary, located 200 miles downstream:
"…total annual flow in the lower Klamath and its estuary has been
altered only to a small degree by water development in the upper
basin, even though water development has had drastic effects on
hydrographs in a number of headwater areas. Thus, changes in
total flow are not sufficiently large to suggest significant
biological effects on the estuary strictly related to flow.
Furthermore, fall flows, even in years of average or above average
moisture, tend to be higher than they were historically at the mouth
of the Klamath, which would indicate that fall
migrations probably have not been impaired by flow depletion per se."
(Emphasis added.)
NOAA Fisheries in its ITS relies on its 2002 BO findings to conclude
it "does not anticipate take of adult coho salmon at flows equal to
and above 1,000 cfs". The 2002 BO incorporated the inconsistent
logic applied to this issue in the draft Hardy Phase II study. In that
study, the authors excluded a recommended flow regime less than 1,000
cfs "under any circumstance". On the one hand, NOAA Fisheries
theorizes that somehow mimicking the unimpaired hydrograph downstream of
the Iron Gate Dam will create ideal conditions (for highly ambiguous
reasons). But on the other hand, it concludes that good conditions for
fish can only occur at the high end of the flow scale (never at the low
end of the scale) and therefore increased flows must be released from
artificially created storage reservoirs. Further, the assumption that a
particular flow for mid-August through October is a necessary precaution
is simplistic and arbitrary. It is clear that a variety of factors
interact, in changing ways, through this period. Critical among them are
air temperature and the timing of runs. An inflexible minimum throughout
this period may be detrimental.
The ITS should be realistic and based on the current situation on the
Klamath River and its tributaries and the opportunities for sustaining
biological productivity as it may be affected by mainstem river flows.
CONCLUSION
The ITS is fundamentally flawed for the reasons stated above. These
deficiencies should be cured in a new ITS and any future BO.
