Big Spirit Lake IA 06-LSR-1655

Assessment Comments

Monitored in 1990 by ISU as part of the Clean Lakes Classifcation study; in 1993 & 1995 for surveys of Water Supply Reservoirs (Miller & Kennedy 1993, 1995); and RAFT Monitoring in 1995.

Basis for Assessment

SUMMARY:  The Class A (primary contact recreation uses) were "not assessed."  Continued to assess support of the Class B(LW) aquatic life uses as "fully supported."  Class C (drinking water) uses remain assessed as "fully supported."  Fish consumption uses also remain assessed as "fully supported."  EXPLANATION:  The level of support of the Class A (primary contact recreation) uses was changed from "fully supported" to "not assessed" due to the lack of information on levels of indicator bacteria at this lake.   This change reflects revisions to the DNR's Section 305(b) assessment methodology and does not reflect any changes in water quality.   The previous (1998) assessment of support of the Class B(LW) uses ("fully supported") was reviewed and approved by the DNR Fisheries Bureau in 2000.   The Class C drinking water use remained assessed as "fully supporting" based on the assessment developed for the 1996 report.   Fish consumption uses remain "fully supported" based on results of EPA/DNR fish tissue (RAFT) monitoring in 1997 (see assessment developed for the 1998 report).
