<br />e <br /> <br />e <br /> <br />e <br /> <br />Appendix - Arden Hills Water Qnality Task Force - June 2000 <br /> <br />LAKE ASSESSMENT PROGRAM <br />COOPERATIVE WORK PLAN <br /> <br />The following is a general work plan for this cooperative program. General work tasks and the <br />group responsible for implementing the work tasks are briefly identified in this outline. Group <br />abbreviations are: <br />Minnesota Pollution Control Agency (MPCA); Lake Association or Local Unit (L4); Soil and <br />Water Conservation District (SWCD) and Department of Natural Resources (DNR). This work <br />plan may be adjusted according to MPCA and LA needs and capabilities. <br /> <br />I. Citizen Lake Monitoring Program (participation is required) (LA) <br />. Weekly measures June to September at 1-2 stations. <br /> <br />II. Water chemistry analysis including nutrients, chlorophyll a, solids, pH, and color, plus a <br />depth profile of oxygen and temperature <br />. Sample collection 1-2 stations 4-5 times/year (MPCA) and (LA). <br />. Sample analysis (MPCA). <br />. Data entry into STORET (MPCA). <br /> <br />III. LakeIWatershed Analysis <br />. Determine lake volume (MPCA). <br />. Define watershed (map) (LA assisted by SW?D or MPGA). <br />. Identify all tributaries (in/out), storm sewers, agricultural tiles, etc., to the lake and map <br />(W. <br />. Estimate land use composition in watershed (seek assistance SWCDJ. <br />. Summary of fisheries and lake level measurements (DNA '). <br />. Assess number of homes around lake noting status (year round or seasonal) and waste <br />disposal system (conduct septic system survey using questionnaire) (LA). <br />. Compile a history of significant events I activities which have occurred around the lake, <br />watershed, or with the association (LA). <br /> <br />IV. Reporting <br />A report will be drafted for each lake by the MPCA with assistance from study cooperators. <br />This report will not serve as a diagnostic .feasibility study (e.g., Clean Water Partnership <br />Phase I) for the lake, but will provide basic information regarding the lake and its <br />watershed. The following items will be included in this report: <br /> <br />. A summary/analysis of water chemistry, fisheries, and physical data. <br />. Assessment of trophic status and trends and comparison with other lakes in the same <br />ecoreglOn. <br />. Map oflake and watershed identifYing tributaries, etc., plus basic morphometric data. <br />. Summary ofland use in watershed. <br />. Recommendations for lake water quality protection or improvement. <br />
