Stop by and say hello to GLEA intern Logan Madison at the Lake Geneva Farmer's Market today until 1pm! We are selling biospheres, resin lakes, and beautiful notecard packs featuring photography by intern Brilie Esser! All proceeds of sales go right back to GLEA to support the work we do. Today is our last day at the market. Wishing our community a great rest of summer!

What does recreational use look like on Geneva Lake? 🚤🌊 Our annual lake-wide count helps provide a snapshot of how the lake is being used...from boats and piers to buoys, swim areas, slow/no-wake areas and more.

A big thank you to the Walworth County interns and volunteers who joined GLEA on the water this year to help us collect data!

Building better habitat takes teamwork! 🐟

A big thank you to Gage Marine for helping GLEA get our fish cribs safely into the water. These structures will provide important habitat for fish and other aquatic life for years to come.

Fish cribs may not look like much on land, but once placed in Geneva Lake, they can provide important structure and habitat for fish.

Here’s a look at why GLEA builds fish cribs, and the process! 👇

Although Monday’s beach sampling results were within acceptable levels, those samples were collected before Tuesday's heavy rainfall. Heavy rain and stormwater runoff can temporarily increase bacteria levels in the lake. Please use extra caution when swimming after heavy rain.

As a precaution, we recommend yellow advisory conditions at Geneva Lake beaches through at least Wednesday morning.
