Assessment Comments

1995 biocriteria: habscr/fshscr = 31/13 (shock, 18 spp., 5 fams.).

Basis for Assessment

Used data from one biocriteria site in Dubuque County to make use support determination.  Fish and habitat metrics from the stream use assessment protocol were applied to the data.  Sampling results indicate very good physical habitat and fish were very abundant and included cold water species such as longnose dace, so.  redbelly dace, rainbow trout, brown trout, and brook trout.
