The federal government has selected the University of Washington in Seattle to negotiate for continuing development of the Comprehensive Passage Model (COMPASS) simulating the migration of juvenile salmon through the Columbia and Snake river hydropower system.
The National Oceanic and Atmospheric Administration said the university was chosen to negotiate an additional contract for COMPASS since it has been involved in the program since its inception and has contributed substantially to model development and data analysis.
“The University of Washington is intimately familiar with the computer program and qualified to contribute to the project in a timely manner,” NOAA said. “No other vendor has the accumulated experience, knowledge, and expertise to continue development of the comprehensive passage model of the migration of the juvenile salmon through the Snake and Columbia rivers.”
COMPASS simulates fish passage and survival over many years relative to hydrology and dam operational rules. It is intended to predict effects of alternative dam operations on salmon survival rates and can be used to assist in the Federal Columbia River Power System Biological Opinion.
