Lake Windsor, beach and dog park closed due to positive bacteria test – Loveland Reporter-Herald

Windsor Lake, the lake beach and the dog park are closed until further notice due to a positive water test for bacteria, the City of Windsor announced Friday.

A precautionary water sample taken from the lake on Wednesday came back positive for cyanobacteria, also known as blue-green algae, according to a news release from the city’s Department of Parks, Recreation and Culture. .

The closure went into effect Friday afternoon and affects the lake, swimming beach and dog beach access.

Almost a year ago, on July 23, 2021, the lake was closed to the public for 17 days due to the presence of the same cyanobacteria in the water.

Rentals and concessions will not be available while the area is closed. Annually licensed motorized and non-motorized boaters are permitted on the lake to help agitate the water. Water activities such as tubing and water skiing are not permitted.

Non-motorized boaters may use permits at their own risk. The city recommends staying out of the water.

Blue-green algae, which isn’t really algae, is a type of bacteria and is common in Colorado lakes, according to the city statement. Algae multiply rapidly – and are affected by a combination of unusually sustained hot weather, standing water and stormwater runoff that includes nutrient pollution from fertilizers – to form blooms and scums.

Polluted runoff can have adverse effects on plants, fish, animals and humans. Too much nitrogen, potassium and phosphorus in water is known as nutrient pollution and can cause algae to grow faster than ecosystems can support it. A significant increase in algae harms water quality, food resources and decreases oxygen for aquatic life.

The addition of sustained warm temperatures allows algae to thrive.

The lake is closed, with immediate effect, the swimming beach is delimited and access to the beach for dogs is locked.

“Earlier this week, our team took precautions and issued a notice to our community in addition to posting messages on our communication platforms,” said Kendra Martin, operations and facilities manager for parks, recreation and culture. . “With the positive results for blue-green algae, staff immediately closed access to the swimming areas of the lake and are actively working to keep our community updated.”

Although permit holders are advised to navigate at their own risk, visitors may continue to use the Dr. Tom Jones Trail, a 2.5-mile trail around the lake, in addition to the volleyball court , catch-and-release fishing, playground, Boardwalk Museum park, and the park in general.

Additional swimming options include the Community Recreation Center (CRC), Chimney Park Pool, and the Eastman Park River Experience. CRC swimming options include a pool with three lap lanes, hot tub, lazy river and waterslide.
