Back by popular demand!
On Tuesday, June 16th we will once again be hosting a plant I.D. class for anyone interested! During the class we will have hands on samples of most aquatic weeds in Delavan Lake. We will cover the good (native) and bad (invasive) plants in our waters and help to educate and identify each species along with the benefits of a healthy aquatic plant ecosystem. After the educational portion we will take a short ride on one of the lake harvesters to see the plants in their natural habitat. Please bring your own life vest, we will have a few on hand, but supply is limited. Looking forward to seeing everyone on the lake!

Workshop Details:
When: Tuesday, June 16, 2026
Time: 10:00am - 12:00pm
Where: Waters Edge, 1220 South Shore Drive, Delavan

As Wisconsin lakes wake up for spring, many property owners are busy putting in docks and preparing for summer.

But spring is also one of the most important times to protect your shoreline.

Heavy rains, snowmelt runoff, and disturbed soil can quickly lead to:
• Shoreline erosion
• Nutrient runoff feeding algae blooms
• Washed-out banks
• Poor water clarity
• Habitat loss for fish and wildlife

Simple steps like maintaining natural vegetation buffers, limiting shoreline disturbance, checking drainage paths, and avoiding unnecessary soil exposure can make a huge difference.

Healthy shorelines protect your property value—and protect the lake for everyone.

A beautiful lake starts at the shoreline.
