Executive Summary
This report is a post-season analysis of the performance of the CRiSP portion of the RealTime/CRiSP complex. Observed 2003 data are compared to predictions made by CRiSP/RealTime during the 2003 outmigration for arrival timing, water temperature, total dissolved gas, flow and spill. CRiSP model runs consistently demonstrate that basic mechanisms of migration can be applied to Columbia River fish movements and their survival tracked downstream. As a part of RealTime/CRiSP, CRiSP is absolutely dependent on the arrival distributions predicted by the RealTime portion of the model and other river environment inputs such as flow and spill data. New this year, additional stocks are tracked in addition to the yearling chinook of previous years. Snake River fish are tracked from Lower Granite Dam downstream. Some Snake and Columbia river ESU stocks are tracked from McNary Dam downstream.
