Documentation
Assessment Comments
Assessment is based on (1) surveys of Nebraska fisheries biologists, (2) consultation with DNR staff and (3) results of fish tissue (RAFT) monitoring.
Basis for Assessment
All fish contaminants were < 1/2 FDA action levels; thus, assessed fish consumption uses as FS. DNR staff used BPJ to assess reach as PS due to siltation and nutrients from agriculture.
