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.

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...

Restoration Efforts Undertaken on the County K Marsh

The GLSD and Lake Management Team Partners have been working for years to improve the water quality entering the lake from the County K marsh. The marsh contributes a disproportionate amount of nutrients to Green Lake than is accounted for by the size of its 3 subwatersheds (Wurches Creek, Spring Creek, and Roy Creek). This has long been a concern to our lake managers. The highly turbid water and lack of aquatic plants indicate the marsh is not functioning as it should. We know that to reduce t...

REFLECTIONS FROM Dave Bartz, DNR FISH BIOLOGIST
