SALT LAKE CITY -- Elevated levels of a harmful algae in Jordan River and lower Little Cottonwood Creek have prompted state and local agencies to post warning signs and limit access to the Jordan River system. Utah Lake remains closed.
Algal blooms can last for days or weeks and toxins can last for days after the bloom. Response agencies don't expect to have a forecast on when the water can be used for any purpose for at least a week.
This warning does not affect drinking water, since it comes from a separate source.
Residents who receive secondary water from the Jordan River should not use it. Secondary water is commonly used for watering lawns and gardens.
Salt Lake County Health Department is posting warning signs at all major recreational access points to the Jordan River within Salt Lake County; the Jordan River and all canals in the county are potentially unsafe for people and animals. The river is not closed at this time.
The Utah Department of Agriculture and Food (UDAF) strongly advises farmers and ranchers against using water from Utah Lake for food production, especially fruits and vegetables, and livestock watering until lab results are available early next week. If farmers and ranchers have access to other water sources UDAF advises them to use those alternative sources to water crops, livestock and other animals.
Pet owners are also advised to keep animals away from the lake, river and canals and should not let them drink the water. Pets that have been exposed to affected waters and are exhibiting symptoms should be seen by a veterinarian. Symptoms in pets include weakness, fatigue and excessive saliva production.
Anglers are also currently advised not to fish, or consume fish from Utah and sections of the Jordan River that feed in and out of the lake. Anyone who has caught fish from those areas in, or after July 10, is advised to not consume their catch.
