Update on GLSD Wastewater Permit Compliance and Future Sewering

DNR WPDES Permit Compliance - As mentioned in previous newsletters, the GLSD is required to meet new, stringent wastewater discharge requirements set forth by the State of WI. District staff continue to work with the WIDNR to gain approval for the use of our treated wastewater as irrigation waters on nearby farm fields. The District is committed to this option as it is both the most environmentally friendly, but also the most cost effective. A demonstration pilot project proposed by the Distric...

2022 Summer in Review

The summer of 2022 was beautiful on Big Green Lake. The minimal snow cover in our area last winter caused limited spring runoff to the lake. Additionally, we saw a very gradual warming of the lake itself along with limited spring and early summer rainfall. These factors helped to create better water quality in 2022 than we’ve seen in many years on Big Green Lake. These observations are reinforced by 2022 USGS water sampling results that showed in-lake phosphorus levels dropped to around 15.5...

What Do Your GLSD Tax Dollars do for Green Lake?

In the last 60 years, the lake has faced negative impacts from increased shoreland development, intensive agriculture throughout the watershed, the advent of harmful aquatic invasive species, increasingly intense rainfall events, and many of the wettest years on historical record. These are significant challenges to overcome. As we work to meet our long-term water quality goals of a roughly 50% reduction in phosphorus loading to the lake, these are some of the programs the GLSD operates to help...

Lake trout release 2022

On April 4th, GLSD and DNR staff moved approximately 30,000 lake trout from our fish rearing facility on North Lawson Drive to Green Lake. Stu Marks and Dallas Lewallen from the GLSD spend 6 months of the year feeding and monitoring the trout. A big thank you to our funding partners as well as DNR staff(Jon Hoffman) for all the time, effort, and direction they provide in helping raise this valuable resourcefor Green Lake.

2022 State of Green Lake Report

On April 11th, Dr. Dale Robertson of the U.S. Geological Survey (USGS), presented the USGS’s annual “State of Big Green Lake” to the GLSD Board of Commissioners and the Lake Management Planning (LMP) Team. The purpose of the meeting was for Dr. Robertson to provide an overview of the recent water quality in Green Lake, nutrient loading (specifically phosphorus) into the lake from the watershed, as well as provide an overview of his conclusions from the Lake Study recently completed by the USGS,...

Results of 2016-2020 Lake Study

In June 2021, a detailed study of Green Lake was completed by the US Geological Survey, Michigan Technological Institute, and the Green Lake Association. The project began in 2016 with the GLA securing a grant to fund the study of depleted oxygen levels within the lake’s thermocline (approx. 30’ below the lake surface). Additionally, the study evaluated phosphorus reductions needed from the watershed to improve the lake’s water quality to un-impaired levels. In the last 40 years, the lake has f...
