Florida LAKEWATCH (FLW) is a research and public outreach program coordinated within the UF/IFAS Department of Fisheries and Aquatic Sciences. FLW facilitates public involvement in the management of Florida waters by training citizen volunteers to collect monthly water samples, algae samples, and water clarity data from a lake or waterbody of their choice. Over time, this information is used to document nutrient levels and/or to predict biological productivity. For more information about the program or to obtain FLW data, call 1-800-LAKEWATch (1-800-525-3928) or view the Web site at http://lakewatch.ifas.ufl.edu/.
