Lake Management Plan
Pier Spraying Permit
LGLPRD Annual Meeting Update April 2021
Little Green Lake Protections and Rehabilitation District board activities since last year's annual meeting. Onterra submitted the pre-approval and the WDNR Grant request to do the core sample testing for a possible aluminum sulfate treatment. This project was approved at last year's annual meeting. Onterra is one of a few companies that have the capabilities of doing this research project. Onterra is the company that put our Lake Management Plan together. The lake clarity is becoming worse each year. We received our point intercept survey that was conducted during the summer of 2019 by the WDNR and Golden Sands. This survey analyzes plant growth, locations and types in our lake. The concerning issue in the report is they found no sign of plant growth in water over 10 feet deep. We believe this is a result of the water clarity deteriorating. The water clarity generally improves by early October each year with visibility improving to around ten feet. The water clarity has continued to deteriorate with this year's first ice being green for the first time. One of the concerns our WDNR Lake biologist had was referred to as perpetual algae. He said the lake is overcome year round with algae. He was happy we were moving forward with testing to see if we would be a good candidate for treatment. The WDNR Grant was approved and Onterra will have done the first core samples by the time you receive this mailing.

Runoff issues on the Krentz farm have been ongoing. We have the WDNR,USDA and Green Lake County have been involved. The farmer did plant a cover crop this fall and planted it horizontally across the hill to reduce runoff. This should help in the spring.
The second area we saw heavy runoff this past summer is on Lakeshore drive. At the annual meeting I told the district there is about 240 acres that is not captured by the two existing holding ponds and that runoff comes down through the woods and crosses Lakeshore Drive. The water can come petty fast down through the ditch since there is about a fifty foot drop from the top of the woods to the road below. We talked about diverting the water to our large holding pond if we could get the property owner to agree either to a long term easement or purchase of some land across the top of the woods. The property owner was not receptive to either option so we are still working with the county to see if we may have any other options at the top of the woods.
We had the driveway into the large holding pond regraded and added gravel late this fall.
Our treasurer Jack looked into restructuring our loans to lock in better rates. Due to the loans we have we cannot do that unless we borrow an additional amount which did not make sense at this time.
The lake did not freeze over like it normally does this past winter.
We are looking into requesting a WDNR Grant for the dam repairs. The initial estimate for this project is $48,000. The grant could cover fifty percent of this amount.
