Nottingham lake in Avon has been closed to swimming, boating, fishing and all bodily contact with the water due to elevated levels of E. coli, according to a recent news release from the town. 

The lake was initially closed on Thursday, when regular testing identified high levels of E. coli in the water. 

“Recreation Department staff chose to close the lake to swimming out of an abundance of caution and are committed to providing safe facilities for our community” said Recreation Director Michael Labagh in the release.

The most recent testing on June 17 determined that E. coli levels were still above the State of Colorado Natural Swimming Area regulations maximum of 235 organisms per 100 milliliters.

According to the CDC, E. coli are bacteria that can be found in the environment, foods, and the intestines of people and animals. Exposure to high levels of E. coli can cause diarrhea urinary tract infections, respiratory illness and pneumonia, according to the center.

“E. coli is a bacteria primarily associated with fecal matter. According to Colorado Department of Public Health and Environment, the elevated levels in Nottingham Lake could be a result of a number of factors, ranging from malfunctioning septic systems, fecal waste from swimmers or animals,” the town said.

The closure will remain in place until testing can prove that the amount of E. coli in the water has returned to a safe level.
