Prospect Lake reopens after closure due to high levels of E. coli

COLORADO SPRINGS, Colo. (KRDO) -- Friday, the City of Colorado Springs announced Prospect Lake in Memorial Park will reopen following a closure due to elevated levels of E. coli.

Thursday, the city closed the lake at noon after learning of the test results. The initial test taken on Wednesday, Aug. 31, returned an E. coli level of 307.6 organisms per 100 milliliters, while the acceptable level for E. coli is 235 organisms per 100 milliliters.

According to the city, Friday's results showed the level at 14.6 organisms per 100 milliliters. 

“Shortly after the first sample was taken for testing, a routine water treatment was performed on Wednesday evening, which likely helped improve the water quality,” said Erik Rodriguez, health, safety and environmental specialist with the Parks, Recreation and Cultural Services Department in a press release. “It’s great news that Prospect Lake will be open for one of our city’s most popular events, the Labor Day Lift Off.”

According to the Colorado Department of Public Health and Environment (CDPHE), Elevated E. coli concentrations may result from fecal waste from swimmers, pets, or wildlife; improperly disposed of dirty diapers; excessive runoff from rain or flood; runoff from urban, suburban, or rural areas; or malfunctioning septic systems.
