THE IMPORTANCE OF LONG-TERM MONITORING DATA IN DEVELOPING AND ASSESSING CERP PERFORMANCE MEASURE GOALS AND TARGETS FOR LAKE OKEECHOBEE

Andrew J. Rodusky Lake Okeechobee Division, South Florida Water Management District West Palm Beach, FL

As part of the Comprehensive Everglades Restoration Program (CERP), alternative water treatment projects such as filter marshes and excess water storage facilities such as reservoirs and regional aquifer storage recovery (ASR) wells are proposed for the Lake Okeechobee watershed. These projects are expected to result in reduced lake stage fluctuations and watershed nutrient

loading, and are expected to improve in-lake environmental conditions.

To assess

effectiveness of these targets will be used.
