Assessment Comments
Assessment is based on results of (1) DNR/UHL biocriteria sampling in 1998 (Fish IBI= 46(fair), BM-IBI= 60(good) and (2) fish tissue (RAFT) monitoring at Pammell Park in 1996.
Basis for Assessment
SUMMARY: The Class B(WW) aquatic life uses remain assessed as "fully supported " (minor impacts). Fish consumption uses remain assessed (evaluated) as "fully supported." EXPLANATION: The aquatic life uses remain assessed as "fully supported / threatened" based on results of IDNR/UHL biological monitoring conducted on this stream segment in 1998 (see assessment for the 2000 report above). These data are less than five years old and, according to IDNR's methodology for Section 305(b) assessments, are thus appropriate for characterizing current water quality conditions. Fish consumption uses remain "fully supported" based on results of U.S. EPA / IDNR fish tissue (RAFT) monitoring in 1996. However, because these fish tissue data are now considered too old (greater than five years) to accurately characterize current water quality conditions, the assessment category for the fish consumption use is changed from "monitored" (indicating an assessment with relatively high confidence) to "evaluated" (indicating an assessment with relatively low confidence).
