SRWD Lake Assessments The Sauk River Watershed District (SRWD) monitors area lakes for nutrient concentrations (i.e. phosphorus), chlorophyll-a, clarity, temperature, and oxygen. Phosphorus is a nutrient that is necessary for plants and controls the amount of algae growth. Sources of phosphorus include: cropland and pasture runoff, bank erosion, human waste, and decaying vegetation. Likewise, chlorophyll-a is the measure of algae in the water. Water Clarity determines how turbid the water is and how much sun light is available for plants. Clarity directly affects photosynthesis processes Lake appearance in August (Courtesy of the Minnesota Pollution Control Agency) in a lake; therefore, poor clarity decreases sun light and also decreases oxygen production. Similarly, water temperature controls the maximum amount of oxygen available for aquatic Approximately consumption. 70% of the lakes monitored in 2009 were classified as Eutrophic or Hypereutropic. SRW D (Courtesy of the Minnesota Pollution Control Agency) Carlson’s Trophic State Index (TSI) lake classification is a general guide to understanding the health of a lake and the current stage of TSI 0 – 35 Oligotrophic - clean lake the lakes life cycle. Summer averages of phosphorus, clarity, and TSI 35 – 50 Mesotrophic - temporary algae & aquatic plant problems chlorophyll-a are used to determine the TSI for a lake. Any lake TSI 50 – 65 Eutrophic - persistent algae & aquatic plant problems TSI > 65 Hypereutrophic - extreme algae & aquatic plant problems with a TSI greater than 59 in the North Central Hardwood Forest ecoregion is listed on the states 303(d) list of impaired waters and considered non-supportive for it’s intended uses. 2009 Sauk River Water Quality Assessment Larger Tributaries of the Sauk River Ashley Creek Hobeken Creek Adley Creek Getchell Creek Stoney Creek Unnamed Creek Kolling Creek Schneider Creek Kinzer Creek Brewery Creek Mill Creek The Sauk River meanders for almost 120 miles from the outlet of Lake Osakis to its The RiverCat is a confluence with the Mississippi River near St. Cloud.

SRWD Impaired Waters “Impaired waters” are waters that do not meet state water-quality standards for one or more pollutants for their designated uses. The Sauk River Watershed District collects samples from area lakes and rivers each year and submits all data to the Minnesota Pollution Control Agency (MPCA) for review. The MPCA has a bi-annual assessment process and releases an Impaired Waters List every even year. The 2010 list is complete and is waiting approval from the Environmental Protection Agency (EPA).
