Do not fund - no response required
Sep 28, 2001
Comment:
Do not fund; a response is not warranted. This endeavor needs much more pre-proposal background research of literature and better interaction with those doing other related Dworshak work. That research might well indicate futility of trying to regulate Dworshak Reservoir withdrawals to significantly reduce entrainment of zooplankton. The proposal fails to indicate any review of basic scientific studies about diel vertical migration of zooplankton; much review of such literature, which is extensive, would be warranted. Several local reports concerning studies on Dworshak reservoir itself were referenced in the proposal text, but none of them was listed in the proposal's reference section (which was empty). More basic literature might reveal that diel zooplankton migration is commonly so rapid and extends so far vertically as to require hourly or more frequent change in draw-off level to avoid their entrainment. This might be difficult even if the dam's outlet structures had been built for draw-off at many elevational increments over the depth of water that zooplankton traverse—and even if dominant competing requirements for water of special temperature (necessitating draw at certain levels) did not exist. The Dworshak rule curve is already extremely complex. Questioning of the presenters indicated that structural and prior-need constraints would likely prevent the draw-off-level flexibility needed to cope with diel migration of zooplankton. If the prospects for managing the draw-off for the intended purpose are not good, studying the zooplankton as outlined would have no value. Sponsor should more thoroughly research zooplankton ecology, and if reasonable prospect of successful management is then seen, submit a revised proposal in a future year.Comment:
Entrainment of zooplankton through Dworshak Dam has not been identified as a limiting factor on kokanee populations in the reservoir. There is some information available that shows entrainment is occurring, but it is not clear how that is affecting the fish populations. The impact of strobe lights on the zooplankton populations should be investigated under project 28024.This project uses hydroacoustic technology to monitor zooplankton movements in the forebay above Dworshak Dam, and then proposes to apply the information to manage dam operations to curtail zooplankton entrainment. The proposal further links zooplankton loss to problems with kokanee management, and ultimately suggests this as an impediment to bull trout recovery. The problem (zooplankton loss), is referenced as a "potential" negative impact, and was "suggested" as a "possible" explanation for poor kokanee growth in '91 and '92 in the proposal. The RFC suggests that the proposal fails to discuss the excellent kokanee growth rates observed in Dworshak in the past 5 years. As a result, the acceptance of zooplankton loss as a management issue is not compelling. There are questions as to whether the proposed methods will be able to differentiate Cladocerans from other zooplankters, suspended detritus, small fish, or Chaoborus spp.
The RFC believes that the proposal reads as a concept paper rather than a project proposal and suggest that the proposal be rewritten so that more detail is provided and a stronger argument is presented as for why entrainment is a limiting factor to the system.
The RFC suggests that a more acceptable approach to this issue may be to first conduct a problem assessment using conventional methods by sampling zooplankton drift in the tailrace. Loss could be quantified and related to gatewell selectors, and diel movement patterns could be inferred (see Novotny and Faler, 1982). An approach such as this could be done for less than ¼ of the existing project's cost as proposed, and then analyzed to see if corrective measures are needed or feasible.

The basic literature might reveal that diel zooplankton migration is commonly so rapid and extends so far vertically as to require changing draw-off level hourly or oftener to avoid their entrainment. This might be difficult even if the dam's outlet structures had been built for draw-off at many elevational increments over the depth of water that zooplankton traverse—and even if dominant competing requirements for water of special temperature (necessitating draw at certain levels) did not exist.
