Mormon Reservoir - A Public Health Advisory related to blue-green algae toxins has been issued on June 23, 2017. There were hopes the high water and cooler spring might stave off a repeat of 2016, but it appears as though conditions are such that a hazardous algae bloom in Mormon Reservoir has warranted a Public Health Advisory issued by South Central Public Health District.
"Take the following precautions when an advisory is in effect:
* Avoid exposure to water experiencing a harmful algal bloom. Take extra precautions to ensure children, pets, and livestock are not exposed to the water.
* Do not consume water with a blue-green algae bloom. Neither boiling nor disinfecting removes blue-green algae toxins from water.
* If fish are known to have been exposed to a blue-green algae bloom, only consume the filet portion (remove the fat, organs, and skin). Wash hands after handling. The risk associated with consuming fish caught in waters with a blue-green algae bloom is unknown. Toxins produced by blue-green algae can accumulate in the organs of fish."

Public Health Advisories will remain in place until samples indicate toxic conditions are no longer present. Past Advisories have remained in place as late a fall to early winter months. See below to monitor any advisory status in Idaho and to get more information.
