AURORA, Colo. - The swim beach at Aurora Reservoir reopened on Friday.
The swim beach was closed Wednesday when routine tests indicated elevated bacterial levels in the water.
The water was tested again and results showed it was safe to swim in, according to the city's Parks, Recreation and Open Space Department.
"The reservoir is an untreated natural body of water, and therefore, it’s not unusual for bacteria levels to fluctuate," officials said. "The elevated levels are likely related to the recent heavy rains experienced in the area."
City officials said the elevated levels would not affect Aurora Water’s ability to provide high-quality drinking water because the city’s chlorination treats bacteria.
The Aurora Reservoir is hosting a two-day triathlon this weekend.
