Lake Wenatchee Food Web Dynamics Monitoring

By Jennifer Hadersberger, Chelan County Natural Resources
For several years, Chelan County Natural Resources Department has worked with the community and fisheries management agencies to develop a plan to evaluate the food web dynamics in Lake Wenatchee. We are excited to announce that we have secured partial funds to start this monitoring effort. This summer, fisheries biologists will begin data collection in Lake Wenatchee, the Little Wenatchee, and the White River to monitor juvenile spring Chinook salmon. The results will help scientists understand the distribution, feeding behavior, growth, and risk of predation as these fish migrate through the Lake. This research will also estimate which fish eat juvenile spring Chinook salmon. This data will also provide an initial estimate for predation losses imposed on juvenile salmon by different predators. Future studies, if funded, will calculate the survival rate of spring Chinook as they migrate through the lake. Data will be collected by Washington State Department of Fish and Wildlife, US Geological Survey, and US Forest Service Research Station. There will be a community meeting later this year to discuss the preliminary results of the data collected this summer.
