SETTING SITE-SPECIFIC EUTROPHICATION STANDARDS FOR RESERVOIRS AND RUN-OF-THE-RIVER LAKES
When adopted in 2008, Minnesota’s lake eutrophication standards defined the need to develop standards on a case-by-case basis for many reservoirs and run-of-the-river lakes. The development of site-specific standards in these waterbodies is required because there is greater variability in the response of trophic status to nutrient enrichment compared to natural lakes. Challenges to developing standards for reservoirs and run-of-the-river lakes include: atypical water chemistry relationships, greater temporal and spatial variability in water quality parameters, and limited biological assessment tools for directly assessing attainment of aquatic life uses (e.g., indices of biotic integrity). The state of Minnesota has developed site-specific standards for several reservoirs and run-of-the-river lakes in the last decade, but to date, they have largely been limited to high-profile waters and those with extensive data sets. The development and implementation of these standards reveal commonalities among these waterbodies that can be used to streamline this process and reduce data needs for determination of nutrient levels that are protective of recreation and aquatic life beneficial uses.
