(KMVT/KSVT) — Authorities have lifted the health advisories for Mormon Reservoir and Thorn Creek Reservoir after toxic algae levels have returned to normal.
South Central Public Health District and Idaho Department of Environmental Quality made the announcement Thursday. The advisories were issued in June 2017 for Mormon Reservoir and July 2017 for Thorn Creek Reservoir due to hazardous algae blooms, according to a news release.
DEQ officials say the agency has monitored the blue-green algae and associated toxins where hazardous algae blooms were present and tests show the levels are normal amd are below the safety threshold.
The agencies advise reservoir users to be cautious in and around areas where the algal blooms are still visible. Water users should always exercise caution around bodies of water with visible slime, surface scum, or a foul odor. High concentrations of toxin-producing blue-green algae may cause illness to both humans and animals.
Any concerns should be reported to DEQ at 208736-2190 or SCPHD at 208-737-5900.
