From the report:
7/21/16 Treatment and SurveyÂ of Lake Truesdale
Observed elodea, white lilies, and duckweed along with floating filamentousÂ algae and unicellular algae. Princeton hydro is working hard withÂ harvester on tracks. I applied copper sulfate to the entire shoreline forÂ floating filamentous algae. There are dense patches of elodea scattered aroundÂ the shoreline where there are dense matts of FFA colonizing on it. Fragments ofÂ elodea floating on the surface of the entire lake. Water is turning green.
