This annual report focuses on the water quality of the five lakes (Como, Crosby, Little Crosby, Loeb, and McCarrons) in Capitol Region Watershed District during the 2015 monitoring season (April through October). Specific water quality data (total phosphorus, chlorophyll-a, and Secchi disk depth) for each lake from 2015 were compared to previous monitoring years. Additional biological and physical parameter results (i.e. phytoplankton, zooplankton, macrophytes, fisheries, lake morphometry, and water levels) are also included in this report. The purpose of this report is to characterize overall lake water quality and health in 2015 and to examine trends over time, which in turn will inform lake management decisions for continued protection and improvement of District lakes. Previous annual monitoring reports (2005-2014) are available on the CRWD website at www.capitolregionwd.org.
