Monthly Lake Report

Lake Management Report- June 2024

WATER QUALITY- Regular water quality tests were conducted at multiple locations around the lake. Parameters such as PH, dissolved oxygen, turbidity, and nutrient levels (nitrates and phosphates) were monitored.

  • pH: Remained within the optimal range of 7.0 to 8.5.
  • Dissolved Oxygen: Average levels were 8.5mg/L, indicating healthy conditions for aquatic life. What is dissolved Oxygen? Dissolved oxygen refers to the level of free, non-compound oxygen present in water or other liquids. It is an important parameter in assessing water quality because of its influence on organisms living within a body of water. In limnology (the study of lakes), dissolved oxygen is an essential factor second only to water itself. A dissolved oxygen level that is too high or too low can harm aquatic life and affect water quality.
  • Dissolved oxygen and aquatic life: Dissolved oxygen is necessary to many forms of life including fish, invertebrates, bacteria, and plants. These organisms use oxygen in respiration, similar to organisms on land. Fish obtain oxygen through their gills, while plant life and phytoplankton require dissolved oxygen for respiration when there is no light for photosynthesis. Shallow water fish need higher levels of dissolved oxygen (4-15mg/L).
  • Where does DO come from? Dissolved oxygen enters water through the air or as a plant byproduct. From the air, oxygen can slowly diffuse across the water’s surface from the surrounding atmosphere, or be mixed in quickly through aeration, whether natural or man-made. The aeration of water can be caused by wind (creating waves), rapids, or diffused aeration systems like we have placed in the southern portion of the lake.
  • Dissolved oxygen from photosynthesis: While most photosynthesis takes place at the surface (by shallow water and algae), a large portion of the process takes place under water (by sub-surface algae and phytoplankton). Light can penetrate water, though the depth that it can reach varies due to dissolved solids and other light-scattering elements present in the water.

  • Turbidity: The average clarity of the lake was measured at 8.8ft this past month. Impressive clarity.
  • Algal blooms: No significant planktonic algal blooms have been observed this past month. Shoreline Filamentous algae was observed in some of the island and mainland shorelines. This has since been treated. Future treatments may be necessary as warmer weather moves in.
  • Fish populations: Bass and Bluegill populations remain very high. We are seeing an abundance of baby fish which is a sign the lakes ecosystem is stable and healthy. We have eradicated around 350 Carp so far this year. Recently, fisherman have been having a good amount of success catching Carp from their boats.
