TriCounty Health has issued warnings for two Basin reservoirs due to Harmful Algal Blooms (HABs). As of July 3rd, yellow warnings have been issued for both Calder and Matt Warner Reservoirs. A yellow warning means that swimming is restricted and boaters need to use caution, though fishing is still considered safe. TriCounty Health is using the announcement as a good time to remind the public to always pay attention to signs posted at reservoirs and lakes regarding recreational safety. Warning signs were posted at both Calder and Matt Warner Reservoirs before the July 4th holiday to ensure the public’s safety during peak recreation days. “The signs are an important indication of water safety levels,” shares TriCounty Environmental Health Director Darrin Brown. “Watch for signs at lakes and pay attention to signage color. If the signs are red, avoid all contact with specified bodies of water.” Harmful Algal Blooms are the result of normally occurring cyanobacteria multiplying quickly to form visible colonies, impairing the water quality with toxins that can have severe effects on health. If you think that you or your pet has been exposed to a Harmful Algal Bloom, call Utah Poison Control at 1-800-222-1222. TriCounty Health asks anyone that sees abnormal, fluorescent-like algae on a body of water and around the shoreline, to call 435-247-1160.
