CRiSP1 Passage
Columbia River Salmon Passage Model

CRiSP1 Passage Columbia River Salmon Passage Model - CRiSP1 predicts downstream migration and survival of individual stocks of wild and hatchery spawned juvenile fish from the tributaries and dams of the Columbia and Snake rivers to the estuary. The model describes in detail fish movement, survival, and the effects of various river operations on these factors. It is also stochastic, incorporating measures of variability and uncertainty into survival predictions.

Current Applications of CRiSP1 Passage:

• Inseason Migratory Forecasts - Predicts the arrival distributions of stocks of outmigrating juvenile salmon at several monitoring sites along the Snake and Columbia Rivers. The tool uses "real time" information about the current status of the runs along with current hydrographic information to predict the future progress of the migrating fish. This is a joint effort of the RealTime and CRiSP1 models.

• Total Dissolved Gas (TDG) Forecasts - For CRiSP.1.6 (Unix only) new equations have been implemented for gas production from spill. As a part of the US Army Corps' Gas Abatement Study, Waterways Experiment Station (WES) has developed these new equations as an improvement over GASPILL, which had been the predominantly used model for gas production. The results from the CRiSP implementation are available for 1996 and 1997.

• Temperature Forecasts - A temperature algorithm was developed for the Inseason Forecasts to predict the current year's water temperature based on historical data, year-to-date data, and a flow forecast. In season flow forecasts are courtesy of Bonneville Power Administration.
