Here’s the release from Colorado Parks & Wildlife (Jason Clay):
Cherry Creek State Park is experiencing natural algal blooms that may be harmful to dogs and humans as a result of a number of things including warmer temperatures, stagnant waters, and nutrient loading from fertilized lawns.
The park has closed the swim area due to elevated levels of cyanobacteria (blue-green algae) growth. The swim area will remain closed until tests provide acceptable conditions to re-open. Blue-green algae has been detected in other areas of the park and caution signs have been placed in visible areas throughout the lake. The Colorado Department of Public Health and Environment (CDPHE) recommends the following:
Keep kids out No pets in water Do not drink water Avoid contact with algae

The Dog-Off-Leash-Area stream has been tested and no visible signs of the algae have been observed.
