Notes

Observed blue-green algae on shoreline, July 18, 2025. Observed scum/foam on shoreline, August 28, 2025. Katepwa Lake water clarity was very good this summer, compared to some previous years. However, observed that there was an increase of evenly dispersed green algae once harvest started in mid-August, and there has since been a lot of "harvest dust particles" in the air.
