Assessment Comments
Assessment is based on results of two October 1995 DNR stream use assessments. See attached document for details.
Basis for Assessment
SUMMARY: The Class B(WW) aquatic life uses remain assessed as "fully supported / threatened." The fish consumption uses remain "not assessed." EXPLANATION: The assessment of support of the Class B(WW) uses remains based on the biological and habitat information from the two October 1995 DNR stream use assessments conducted on this reach of the Boyer River (see assessment for the 1998 report). A review of the field sheets from the October 1995 DNR stream use assessments near Deloit and at the Sac/Crawford county line shows (1) presence of a relatively diverse fish community for streams in the Loess Hills and Rolling Prairies (47e) subecoregion (14 species from 4 families and 9 species from 4 families), (2) presence of nearly all the expected fish taxa (6 of 7) for streams in this subecoregion at both assessment sites, and (3) presence of the expected game fish species (channel catfish) at both assessment sites. According to DNR's assessment methodology for Section 305(b) reporting, these results suggest that the Class B(WW) aquatic life use are "fully supported / threatened." The fish consumption uses remain "not assessed" due to the lack of fish tissue monitoring in this reach of river.
