Recreation Water Quality Health Advisories
This page provides information related to current recreation water quality health advisories involving cyanobacteria harmful algal blooms (HAB) and E. coli bacteria. The map and information table are updated with the most current information as health advisories are issued and lifted throughout the season.
Remember: Only a fraction of all water bodies in Idaho are monitored due to limited physical and monetary resources. The absence of an advisory is not an indication that a HAB or E. coli is not present at a water body. You are your own best advocate when ensuring your safety, and that of your family and pets. Be aware and "when in doubt, stay out."
