Documentation
Assessment Comments
Assessment is based on BPJ of DNR staff and 1991 fish tissue (RAFT) monitoring.
Basis for Assessment
Used information from 1991 RAFT site to assess fish consumption uses as FS (all contams < 1/2 FDA action levels). Used my (JRO) BPJ to assess aquatic life support as PS due to habitat alterations that have resulted from the hydrological modifications of the river and from alterations of the flow regime.
