East Lake (Lenox) IA 05-PLA-1478

Assessment Comments

Assessment is based on results of a 1995 UHL survey of water supply reservoirs.

Basis for Assessment

SUMMARY:  The Class A (primary contact recreation) uses and the Class B(LW) aquatic life uses remain "not assessed."  The Class C (drinking water) uses remain assessed (evaluated) as "fully supported / threatened" based on results of a 1995 UHL survey of water supply reservoirs.  

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 assessment.   This lake is not part of the ongoing statewide survey of 132 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 for more information).   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.
