OVERALL LAKE EVALUATION
Loeb Lake exhibits the best water quality of any District lake, and has historically received an ‘A’ lake grade, indicating high water quality and user quality. This could be the result, however, of a very small watershed: lake area ratio, with very little runoff (carrying external pollutants) entering the lake. Loeb Lake held an abundant amount of aquatic vegetation in 2013, but most species monitored (aside from coontail) only showed moderate abundance throughout the lake area. Previous reporting on Loeb Lake focused on an analysis of TP, Chl-a, and Secchi depth trends over the monitoring season and compared to past monitoring years. Conversely, this report contains more extensive information on lake history, lake morphometric data, lake level, additional water quality analysis (i.e., lake grading), phytoplankton and zooplankton populations, aquatic vegetation communities, and fish populations. For this year’s report, this information was solely reported upon, but not analyzed for trends or relationships between parameters. A more robust analysis will be done in future monitoring reports that examines the interactions between all parameters monitored in order to present a picture of the overall health of Loeb Lake. 2013 CRWD Lakes Monitoring Report
