Why Your Report Matters

Every case report strengthens the community's ability to protect itself from swimmer's itch.

Help Others Stay Safe

Real-time reports let swimmers check conditions before getting in the water. A report this morning could protect a family this afternoon.

Build the Evidence Base

Aggregated case data helps researchers and lake associations demonstrate the scope of the problem when applying for DNR permits or pursuing control programs.

Track Outbreak Trends

Seasonal patterns, wind correlations, and severity changes over time help identify which lakes have which varieties — and what control efforts are working.
