Biological Outcomes of this project: The expected biological outcomes are 1.) to see the survival rate improve for kokanee eggs incubating on the shorelines of the lake, to see the over-winter survival of warm water fish in the Pend Oreille River improve thereby creating a new fishery , to determine what effect predators have on the lakes kokanee population, to determine if changing lake levels improve aquatic macrophytes around the lake and thereby increase waterfowl abundance, and to see that opossum shrimp (Mysis relicta) do not affect the abundance or survival of newly emerged kokanee fry.
Biological Data: We have data sets on kokanee abundance, by year class, from 1977 to 1999, recorded annually. These 22 years of kokanee populations estimates have confidence limits of plus or minus 20 to 40% for each age class. Kokanee survival rates were estimated between each of these years (from 1977 to 1999). We have counts of kokanee spawning along the shoreline and tributary streams, in standardized areas, for most years from 1972 to 1999. Kokanee length and weight at each age has been recorded for each year of trawling. Shrimp densities have been estimated from 1977, 1986-1990, 1992, and 1995-1999. Waterfowl abundance on Lake Pend Oreille has been estimated from 1971 -1999 during January of each year. The quality of shoreline gravel for kokanee spawning has monitored annually at five sites during 1992, 1998 and 1999. Riparian areas of the shoreline were photographed in 1998 and 1999 to document the lack of change in vegetation. Hydroacoustic estimates of all pelagic fish in the lake have been estimated annually from 1995-1999. Population estimates of Kamloops rainbow trout, bull trout, and lake trout, were made in 1998. Food habits of these predators were defined and bioenergetically modeled to determine the amount of kokanee consumed. Limnological parameters of temperature, oxygen content, and Secchi transparency were measured monthly, spring through fall, 1997-1999.

Section 2. Past Accomplishments

Year Accomplishment
1997 This was the first year of the project. The U.S. Army Corps of Engineers successfully changed the winter lake levels which added 1.8 million square feet of spawning gravel to the lake.
1997 Kokanee fry survival was measured but did not improve. This was also bad flood year ; a 100 year event.
1997 Three University of Idaho 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 which should improve rearing success.
1997 Shrimp population was successfully measured by random sampling in three sections of the lake and was numerically stable. A stable shrimp population will benefit the experiment.
1998 Kokanee population successfully measured by trawling and hydroacoustics. Fry abundance was very low.
1998 Graduate student study successfully shows that newly emerged kokanee do not starve because of competition with Mysis shrimp. Study also shows that food was not limiting for kokanee in 1998.
1998 Extensive sampling of shoreline spawning gravel shows very little siltation due to changing lake levels during the first two years.
1998 Higher lake levels during the winter of 1997-98 may have contributed to higher egg-to-fry survival rate of 9.9% (up from 1.4% in 1995).
1999 Higher lake levels during the winter of 1998-99 may have contributed to higher egg-to-fry survival rate of 6.0% (up from 1.4% in 1995), but questions were raised about compensatory responses of the low kokanee population.
1999 Graduate study on predation estimates 114 tons of kokanee are eaten per year from the lake. This was not a problem in 1996 but may have contributed to kokanee declines in 1999.
1999 Shrimp population in lake was successfully measured for fifth straight year and was found to be stable even though kokanee numbers declined. Shrimp abundance appears to be controlled from below (primary production) not above (by predation).
1999 Shrimp sampling conducted with both vertical net tows and a high speed Miller sampler. Density estimates can now be inter-converted between the two methodologies.
1999 Gravel sampling on shoreline areas shows strong movements in shoreline gravel. This indicates the need for lower lake levels approximately once ever 4 years to move gravel to lower pool level.
1999 Graduate study on the Pend Oreille River shows importance of over-winter habitat to the warm-water fish populations. Study is still in progress.
1999 Kokanee population successfully measured by hydroacoustics. Hydroacoustics yielded population estimates with 90% confidence limits of + or - 9% for fry and 17.8% for 1 to 5 year olds.
1999 Kokanee population successfully measured by mid-water trawling. Trawl estimates yielded population estimates with 90% confidence limits of + or - 28% to 64% for different age classes. Older age classes found to be declining.
