Section 2. Past Accomplishments

Year Accomplishment
1997 First year of project. US Army Corps successfully changed winter lake level.
1997 Three University projects were started.
1997 Kokanee population was successfully measured by hydroacoustics, trawling and spawner counts.
1997 Kokanee spawning activity was mapped on 100 miles of shoreline. Kokanee were documented to have moved into new shoreline areas for spawning.
1997 Depths of kokanee spawning were measured. Kokanee were found to have moved on to newly available gravel at shallower depths.
1997 Shrimp population was successfully measured by random sampling in three sections of lake.
1998 Kokanee population successfully measured by trawling and hydroacoustics. Fry abundance very low.
1998 Graduate student study successfully shows that newly emerged kokanee do not starve because of competition with Mysis shrimp.
1998 Extensive sampling of shoreline spawning gravel shows very little siltation due to changing lake levels during first two years.

Section 4. Objectives, Tasks and Schedules

Objectives and Tasks

Objective Task
1. Recover kokanee abundance so that a harvest of 750,000 fish can be maintained on an annual basis. This would require an adult kokanee population of 3.7 million fish. a. U.S. Army Corps of Engineers raises the lake level 4 feet during the winter of 1996-97, 1997-98, and 1998-99.
1. Sub-objective: determine if adult kokanee population reaches 3.7 million and determine if egg to fry survival exceeds 3.6%. b. Conduct mid-water trawling in the lake to determine population estimates, biomass, age, and size of kokanee. Estimate number of eggs being laid.
1. Sub-objective: verify the accuracy of trawling and determine its net-efficiencies. c. Conduct mobile hydroacoustic surveys to estimate age classes of kokanee and determine location of fry.
1. Sub-objective: determine trend of lake levels to kokanee population and its statistical significance. d. Compare kokanee population to past data and relate to changes in lake level using multiple regression analysis.
1. Sub-objective: use spawning kokanee abundance as a surrogate index of adults, look for a doubling of spawning fish. e. Conduct spawner counts of kokanee along shoreline and relate to past data.
1. Sub-objective: determine if egg to fry survival exceeds 3.6%. f. Calculate survival rates of kokanee and determine if lake level changes cause changes in survival.
1. Sub-objective: determine if kokanee pioneer new areas to reduce intra-specific competition of fry and determine if kokanee use the cleaner newly created gravel to improve survival. g. Map location and depth of kokanee spawning along 100+ miles of shoreline.
1. Sub-objective: try in-situ experiments to estimate improvement in egg to fry survival. h. Place kokanee eggs in Vibert type boxes and bury in the shoreline substrates of different qualities to determine changes in incubation with changed lake levels.
1. Sub-objective: determine changes in wild fry survival without masking the effect by stocking hatchery fish. I. Cold-brand the otoliths of all hatchery produced fry that are stocked into the lake so that they can be separated from wild fry.
1. Sub-objective: provide a diagrammatic over-view of the relationships within the lake, as per Power Planning Council’s request. J. Build a systems model (not a computer model) of the lake as well as a sensitivity analysis of the state variables and feedback loops to show determinants of recruitment and survivorship.
2. Have no net change in the amount of shoreline spawning gravel due to erosion or siltation during this experiment (maintain 1.7 million sq. feet). a. Monitor the quality of shoreline gravel by scuba diving and analyzing the silt, sand, gravel, and cobble content.
3. Increase the warm water fish population in the Pend Oreille River seven fold. a. Change the winter elevation of the river 4 feet. (This task is being done by the U.S. Army Corps.)
3. b. Monitor warm water fish populations in the Pend Oreille River by gillnetting, seining, and electrofishing and compare to data collected in 1991 and 1992.
3. c. Determine year class strength and over winter mortality of fish produced with changed river levels.
4. Determine whether other factors could be limiting the kokanee population by either competition or predation. a. Build a year-round energy budget model for the lake including zooplankton, shrimp, kokanee, and predators.
4. b. Monitor zooplankton weekly during spring and fall and monthly the remainder of the year.
4. c. Sample shrimp annually to determine density and abundance.
4. d. Estimate predator abundance using mark and recapture methodology.
4. e. Electro-fish shorelines to define impact of near shore predators.
4. f. Calculate consumption of predators using bioenergetics and incorporate into energy model.
4. g. Survival of wild fry will be correlated to hatchery stocking to determine potential impact of hatchery fish.
5. Keep Eurasian milfoil from becoming a significant problem in Lake Pend Oreille a. Conduct a literature review of the life history of milfoil.
5. b. Map areas of the lake that are milfoil habitat.
5. c. Search for milfoil along 100+ miles of shoreline.
5. d. Determine limnology at location of milfoil sites.
5. e. Design site-specific management recommendations.
5. f. Document plant community response during years of deeper drawdown.
6. Determine any large impact of changed lake levels on riparian vegetation and waterfowl as per Councils request. a. Photo documentation of representative shoreline vegetation will be made during and after years of high water.
6. b. An annual waterfowl count will be made from a fixed wing aircraft.

Other Budget Explanation

Schedule Constraints: Project requires the cooperation of the U.S. Army Corps of Engineers to change lake levels each winter. Cooperation has been excellent through the first 2 years of study and is expected to be so during the last year of lake level changes in the winter of 1998-99. Severe flooding during test years could delay documenting the benefits of higher lake levels. Last year, the ISRP recommended that the lake be held higher for 10 winters. We are actively pursuing this extension. A letter was sent from the Director of the Idaho Department of Fish and Game to the Colonel of the Corps of Engineers in Seattle making this request. So far there has not been any response which would indicate a change in our current proposed schedule.

Section 7. Abstract


Reviews and Recommendations

This information was not provided on the original proposals, but was generated during the review process.

ISRP Preliminary Review , ISRP 99-2 Recommendation:
Jun 15, 1999
[There are no budget numbers associated with this review.]
Recommendation: Fund. Recommend for funding for a longer duration. The project should be funded to cover at least one and preferably two kokanee generations. OK for multi-year review cycle; review in FY2002 for analysis of results. (Priority for Lake Pend Oreille fishery.)

Comments: This project proposes to elevate winter water levels in Lake Pend Oreille by four feet to investigate whether or not it will have a positive impact on kokanee salmon abundance by increasing available spawning habitat and on warm water species in the Pend Oreille River by increasing the amount of suitable over-winter habitat. In addition, the project will simultaneously investigate whether competition with Mysis shrimp for food and predation by Kamloops, bull trout, and lake trout play a significant role in regulating kokanee abundance. The project was initially reviewed by the ISAB in 1997 as an experiment to see if keeping lake elevations high in winter would aid kokanee spawning and increase the lake population. The ISAB concluded that, given natural variability and numerous confounding factors, the time frame of essentially a little more than one kokanee generation is probably too short to reach definitive conclusions. This can be rectified by extending the length of the project and including study of the other factors.

The proposal is thorough and scientifically sound, except for the point brought up by last year's reviewers that a longer time frame is needed. It includes work on other factors possibly related to kokanee abundance that were considered by the ISAB. The proposal references the FWP and one other plan. There are no other projects on Pend Oreille Lake to reference. There is an excellent list of objectives and tasks. University studies are included as well as the funded work. The schedule has been maintained despite abnormally high flows, and there is consideration of a longer time frame for the work (which the ISAB and ISRP have encouraged). The narrative sections are all excellent. The rationale appropriately links the work to CBFWA criteria. Accomplishments are listed and discussed in relation to the abnormally high flows. There has been good progress. The proposal should give more detail on the three projects that are subcontracted.

(g) Lake Pend Oreille kokanee study

The Council dead-locked on a motion to recommend that the Corps of Engineers hold the lake level at the higher elevation for an additional year beyond the three years specified in the program measure related to this proposal. For this reason, the Council did not make a formal recommendation for a specific lake level for the 1999-2000 operations. The Council did vote to approve funding project #9404700 for Fiscal Year 2000. The project sponsor verified that the study activities could continue and the work would be valuable whether the Corps of Engineers chose the higher or lower lake level in 1999-2000.
