Centerville Reservoir Lower IA 05-CHA-1319

Assessment Comments

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

Basis for Assessment

The Class A (primary contact recreation) uses and Class B(LW) aquatic life uses remain "not assessed."  The Class C (drinking water) uses remain assessed (evaluated) as "fully supported / threatened."  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 for the 1996 report above.   However, 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.
