Stream trace modeling analysis used to track fish passage

摘要

Stream trace modeling analysis, which allows users to predict movement of fish, has proven useful in analyzing swimming patterns of fish at hydro projects. To illustrate the predictive paths of sub-yearling chinook and sockeye smolts, researchers with Hydroacoustic Technology Inc. (HTI) tested this technique at 1,312-MW Rocky Reach Dam on the Columbia River in Washington.
