Notice of availability of final document.

SUMMARY:

The U.S. Environmental Protection Agency (EPA) announces the availability of a final document, Ecological Risk Assessment for the Middle Snake River, Idaho (EPA/600/R-01/017, February 2002), prepared as a collaborative effort between the National Center for Environmental Assessment-Washington (NCEA-W), within EPA's Office of Research and Development; the Office of Environmental Assessment, Region 10 of the EPA; the University of Idaho; and the University of Illinois. Mathematical models and field observations were used to estimate ecological risks to rainbow trout, mountain whitefish, and white sturgeon from stressors such as reduced water flows and sedimentation. The report serves as an example of using ecological risk assessment to improve the use of sound science in watershed-scale decision making.
