Rain Gardens: Your Personal Contribution to a Cleaner Green Lake

As mentioned briefly in our spring newsletter, the GLSD currently has a wonderful cost share program rain gardens in addition to shoreline restoration. A newer conservation practice, rain gardens are becoming popular nationwide as many landowners look to limit stormwater runoff from their properties. WHAT IS A RAIN GARDEN?Rain gardens are sunken gardens planted with wildflowers and other native plants that collect and soak up rainwater, mainly from the roof of a house, garage, or driveway. T...

GLSD Wastewater Permit Compliance and Future Sewering

WPDES PERMIT COMPLIANCEAs mentioned in previous newsletters, the GLSD is required to meet new, stringent wastewater discharge requirements set forth by the State of WI. The DNR regulates the discharge of pollutants to waters of the state through the Wisconsin Pollutant Discharge Elimination System (WPDES) program. Permits are issued for a five-year term. Like wastewater utilities all over WI, under the next permit (beginning in October of 2022) the DNR is requiring the GLSD to significantly red...

Results of 2016-2020 Lake Study

This past June, 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...

BMP Spotlight – NO TILL

The best management practice of ‘no-till’ is just what is sounds like. A no-till field management system avoids disturbing soil with tools like chisel plows, field cultivators, disks, and plows. Plowing breaks up the soil surface or flips the top layer of soil which breaks up soil stability and incorporates nearly all crop residue deeper into the soil profile. No-till management of crop fields allows the previous year’s crop to help hold and cover bare soil. This helps retain soil on fields use...

Protecting Green Lake One Property at a Time

RAIN GARDENSThe GLSD has a wonderful cost share program for not only shoreline restoration, but also rain gardens. A newer conservation practice, rain gardens are becoming popular around Green Lake as many landowners look to limit stormwater runoff on their properties. The GLSD is excited to have been involved with two projects in the Green Lake Terrace area last fall. While these two projects will not solve the runoff issues in the Terrace on their own, we know that as more landowners complete...

Concerning Information Regarding the State of Green Lake

On April 14th, 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, the GLA Board of Directors, and the Lake Management Planning (LMP) Team. The focus of the meeting was for Dr. Robertson to provide an overview of the nutrient loading (specifically phosphorus) into the lake from the watershed as well as recap lake sampling results from 2019 and 2020. Phosphorus is the main nutrient that drives plant an...

Beach Sampling

As in the past, the GLSD weekly beach sampling around the lake ran between Memorial Day and Labor Day. We sample at each public beach as well as several boat launches to determine the E. coli levels at these locations each week. E. coli is a bacterium commonly found in the intestines of humans, birds, and other animals; some strains of which can cause severe illness. In July, a sample taken at Sunset Park on the east end of the lake, showed excessively high levels of E. coli. Concerned about th...

New AIS Tool Boards

The new AIS tool boards were installed by the county and townships at boat launches around the lake. This was a GLSD and Partner supported project to help keep new aquatic invasive species out of the lake. A big thank you to Anna Cisar, our AIS specialist with Golden Sands RC&D, along with Stephanie Prellwitz of the GLA, and Paul Gunderson and Jordan Dornfeld of Green Lake Land Conservation for their efforts to stop the spread of AIS into Green Lake.

BMS Spotlight – Cover Crops

Cover crops are grasses, legumes, and other forbs that are planted for erosion control, improving soil structure, moisture, and nutrient content, increasing beneficial soil biota, suppressing weeds,providing habitat for beneficial predatory insects, facilitating crop pollinators, providing wildlife habitat, and as forage for farmanimals. Although cover crops can perform these multiple functions in an agroecosystem simultaneously, they are most often grown for the sole purpose of preventing soil...

Waste Management Update

There have been many surprising footnotes to the Covid pandemic. One such tidbit is that when people are forced to stay home, apparently they clean house! In speaking with Waste Management this spring and summer, they updated us on the fact that residents within the GLSD put out more than 15% more trash in the 2nd quarter of 2020 than average. WM found this trend to be similar across all the communities it serves. Additionally, WM has seen a huge increase in cardboard being thrown away due to t...
