Key findings
In the authors’ words, from the slides:
- Low oxygen and high phosphorus in the deep water
- Oxygen level after ~12ft reduces to zero. This is consistent in the testing periods for 2015 and 2020 therefore the low oxygen at the lower depths appears to be the natural state of the lake
- Total phosphorus in the deep water is consistently high but a trendline when including the last two years (right side plot) suggests a decrease although there is not enough data for confirmation
- State confirmed a toxic blue green algal bloom in 2014
- It is important to confirm a true algal bloom
- Algal Toxin Testing: Recommended supplement to the CSLAP testing to identify toxic blue green algae
Plan and Options
- Visual inspection of lake perimeter and accurate identification of algal blooms
- CSLAP monitoring
- Adding beneficial plants, e.g., American Bur Reed
- Testing for green algal toxin
- Chemical treatment if necessary
