Objective(s): To provide baseline data on fish, benthic invertebrates, plankton & limnology; to provide information on fish species presence/absence in addition to population estimates in designated project area streams and lakes; to evaluate the degree of utilization for each fish species of fish habitat; to document fish biological parameter; to investigate fish diets; and to obtain fish tissues in order to determine background metal levels.

Project Description: In project area streams, fish presence/absence and/or densities will be obtained by electrofishing representative habitat. Benthic invertebrates ans periphyton (stream algae) will be sampled at stream sites to determine seasonal changes in composition, distribution and abundance. Lake fisheries population studies will involve fish trapping. Lake limnology, plankton and benthic invertebrates will be done by grab sampling, plankton tows & profiling
