Condition: EXCELLENT

  • 5-Year Average Trophic State: 42/Mesotrophic (Source: Wisconsin DNR)
  • Secchi Disk (2018): Average summer reading = 10.7 ft. (SE Georegion average = 6.8 ft). Summer (July/Aug) water was reported as CLEAR and GREENGreen normally suggests a lake impacted by algae. However, since recent summer chlorophyll readings average less than 9 ug/l, this lake may have been impacted by another factor, such as suspended marl.
    A graph of water clarity
  • Chemistry (2018): The average summer Chlorophyll was 3.6 µg/l (compared to a Southeast Georegion summer average of 31.6 µg/l). The summer total Phosphorus average was 19.2 µg/l. Lakes that have more than 20 µg/l and impoundments that have more than 30 µg/l of total phosphorus may experience noticeable algae blooms.
  • Trophic State Index (TSI) (2018): 43/Mesotrophic. What does this mean?
    Mesotrophic lakes contain moderate amounts of nutrients, and contain healthy, diverse populations of aquatic plants, algae, and fish. Occasional algae blooms may occur. If the lake is deep enough to stratify, the hypolimnion often becomes low in oxygen by the end of summer, and may result in some phosphorus release from the sediments. Mesotrophic lakes are characterized by moderately clear water, but have a increasing chance of low dissolved oxygen in deep water during the summer.

Condition is based on Wisconsin DNR data from volunteer readings taken on 20 different days in April-Sep in 2018.

  1. See web page under department tab Sanitary District 1 Cedar Lake for several current and past fish reports from the DNR along with other water quality data and information. Note that the 1966 DNR map reflects a lake level 3+ feet lower than current relatively stable lake level conditions. One island is a submerged obstruction now.
