25. 12/18/08 25 WDFW Comment: Spada Lake Fishery Studies completed in 2007 / 2008 Studies completed in 2007 / 2008 –Review of past studies and existing information (UW) –Field studies (Meridian / Shuskan / UW) Fisheries and aquatic resource investigations Fisheries and aquatic resource investigations Limnology Limnology –Bioenergetics Modeling (UW)

26. 12/18/08 26 Spada Lake Trout Production (RSP 16): Study Objectives Use bioenergetics simulations to determine whether food supply, food quality, thermal regime, or density-dependent growth from inter- or intra-specific competition limit trout production. Use bioenergetics simulations to determine whether food supply, food quality, thermal regime, or density-dependent growth from inter- or intra-specific competition limit trout production. Explore management options the promote increased productivity. Explore management options the promote increased productivity.

27. 12/18/08 27 Spada Lake Trout Production (RSP 16): Results Summary The combination of warm summer epilimnetic temperatures and a shift to lower energy content prey primarily limit growth and production of trout in Spada Lake compared to early Stage II operations. The combination of warm summer epilimnetic temperatures and a shift to lower energy content prey primarily limit growth and production of trout in Spada Lake compared to early Stage II operations. –Shift in the benthic community (loss of energy rich leeches and mayfly naiads) or spatially or behaviorally inaccessible –Shift to feeding on terrestrial insects comes with increased metabolic costs / reduced growth efficiency

28. 12/18/08 28 WDFW Comment: Spada Lake Fishery Comments to date Comments to date –No formal comments received –Informal discussions with WDFW and City of Everett
