The Crystal Lake & Watershed Association

is a nonprofit (501c3) organization of concerned citizens committed to protecting the beauty and water quality of Crystal Lake and its surrounding environment. It engages in monitoring, education, and advocacy on behalf of the broad community for whom Crystal Lake is a vital economic, recreational, and aesthetic resource.

Swimmer’s Itch reporting

Merganser trapping and relocation has ended for 2021. Birds around the lake now are adults and adolescents — the CLWA only traps BROODS before the babies are able to fly.

The online system to report cases of swimmer’s itch is still functioning, and we urge you to use that if you are affected. Just click the “button” below. Your swimmer’s itch report will enter the CLWA scientific data base to assist continuing research.

For more on swimmer’s itch and how to avoid it, see the CLWA brochure HERE.

The CLWA thanks you for your help in controlling swimmer’s itch on Crystal Lake!
