The Boulder Reservoir swim area is closed at least until noon Wednesday because of high levels of bacteria found in the water.

Wildlife activity may be the reason for the elevated bacteria levels, according to Boulder Parks and Recreation.

The reservoir swim area will reopen once water sampling tests show acceptable levels.
