The ISDA early detection system has found quagga mussel veligers along parts of the Snake River. Further investigation will determine the scope of the spread and the best treatment and control strategies to implement. The very best method of treatment, however, is always prevention. So remember, to keep Hayden Lake and its surroundings clear of aquatic invasive species, always remember to CLEAN, DRAIN, & DRY!

ISDA’s weed surveys are complete, and they have found Eurasian Watermilfoil in Hayden Lake again this year.

The Lake Debris Removal Program is a cooperative, community project. The water surface is publicly owned by the State of Idaho, so you’re on public property when you are on the water. In contrast, the shoreline is mostly private, and we want to be thoughtful about the homeowners and shoreline in Mokins Bay, where we have permission to stage lake debris before its removal in June.
