BEAR LAKE PROTECTION & REHABILITATION DIST: Bear Lake Water Quality and Fish Survey Study

Evaluation of impact of previous stunted panfish removal efforts involving collection of new fish survey information using 10 fyke nets for 5 days in June. All fish will be counted and weighed with approximately 10% being individually measured. Fish will be handled according to DNR instructions. New information will be combined with previous DNR fish surveys and information on panfish and gamefish and when lake district first started removal project. Data will be evaluated in terms of panfish over 5C6 inches, walleye over 15 inches and bass over 12 inches, calculations will be made based on technique developed by Hambright et al. Water quality monitoring during sring and fall turnovers and once per month in June, July and August. Samples will be collected at depths and for parameters as described in item 2 on page 4 of project description in application. Preparation of nutrient budget for Bear Lake will include watershed map showing land use prepared and will use unit areal loading method toestimate pollutant loading from the watershed. Internal phosphorous loading will be estimated from data collected and literature sources. Phosphorus loading models will be evaluated for applicability and used to refine the nutrient budget.
