Steamboat Springs The Steamboat Lake swim beach remained closed Thursday after second tests for E. coli hadn’t come in.
The lake closed Wednesday after E. coli levels exceeded 235 organisms per 100 milliliters. Steamboat Lake State Park Ranger Matthew Schuler said in an e-mail that the laboratory likely didn’t receive the second test Thursday. Park officials hoped to open the swim beach as soon as this afternoon.
Schuler said Wednesday that the high levels of E. coli most likely appeared because the test was done when high winds were blowing into the beach, concentrating particles in the area.
The swim beach also closed in late June because of heightened E. coli levels. The park tests the water weekly for the bacteria and twice a week on peak summer weekends.
E. coli is a bacteria that is found in the intestines of animals, including humans, and spread through feces. If ingested it can cause illness, with symptoms normally appearing in two to four days.
