Assessment Comments
Basis for Assessment
Continued to use the assessments of support of the Class A primary contact recreation and Class B(LW) aquatic life uses (both = PS) used for the 1996 report. Both uses are believed impaired by turbidity and siltation related to delivery of silt from the watershed. These assessments were reviewed and approved by the DNR Fisheries Bureau. This lake was placed on Iowa's 1998 list of Section 303(d) waters due to water quality impacts from turbidity and siltation.
