Assessment Comments

Assessment based on results of a 1995 UHL survey of Iowa water supply reservoirs (Miller and Kennedy (1995).

Basis for Assessment

SUMMARY:  The Class A (primary contact recreation) uses and the Class B(LW) aquatic life uses remain "not assessed" due to the lack of water quality information upon which to base an assessment.    The Class C (drinking water) uses remain assessed (evaluated) as "fully supported / threatened" based on the results of the UHL survey of water supply reservoirs in 1995.  

EXPLANATION:  The Class A and Class B(LW) uses remain "not assessed" due to the lack of recent water quality information upon which to base an assessments.   This lake is not part of the ongoing statewide survey of Iowa lakes conducted by Iowa State University.  

The Class C (drinking water) uses remain assessed (evaluated) as "fully supported / threatened" based on results of sampling conducted by UHL in January 1995 (see assessment developed for the 1996 reporting cycle).   Because these data are now considered too old (greater than five years) to accurately characterize current water quality conditions, the assessment category is changed from "monitored" (indicating an assessment with relatively high confidence) to "evaluated" (indicating an assessment with relatively low confidence).   Fish consumption uses remain "not assessed" due to the lack of fish contaminant monitoring at this lake.
