The Class BLW use was assessed (evaluated) as "WINOFI" based on information from the DNR Water Quality Bureau and Fisheries Bureau. All other designated uses were “not assessed.”
Class BLW - The Class BLW aquatic life use was assessed (evaluated) as "WINOFI" based on information from the Iowa DNR Fisheries Bureau. According to local DNR fisheries Biologist, this lake has excessive turbidity and little to no aquatic plant life. Turbidity issues likely due to excessive nutrients and/or high densities of common carp. Additionally,accordingto Water Quality Bureau Monitoring Staff, this system suffers from high turbidity and significantalgal blooms. The assessment category for this wetland of "evaluated" indicates that the assessment is based entirely on "best professional judgment." In terms of Section 305(b) reporting, "monitored assessments" are based primarily on recent, site-specific ambient monitoring data and thus have relatively high confidence. DNR considers waterbodies identified as "impaired" based on "monitored assessments" as candidates for the state's Section 303(d) list. "Evaluated assessments" are those based on data older than five years or other than site-specific ambient monitoring data (e.g., questionnaire surveys of fish and game biologists [=best professional judgment]) and thus have relatively lower confidence. DNR does not consider waterbodies identified as "impaired" based on "evaluated assessments" as candidates for the state's Section 303(d) list. Class HH - Fish Tissue sampling: No Data In general, Iowa wetlands are not managed for recreational fisheries; thus, fish contaminant monitoring is not typically conducted at these waterbodies.
