Prospect Lake is closed until further notice due to the return of blue-green algae.
During the closure, the following activities are prohibited: swimming, bathing, paddle boarding, tubing, water skiing and non-motorized boating of any kind. No pets are allowed. The use of permitted motorized boats is encouraged as this activity can help aerate the water. Fishing areas will remain open, though anglers are urged to clean fish well and remove guts.
The lake is being treated with an enzyme-based, non-pesticide treatment that consumes the biomass at the bottom of the lake and helps oxygenate the water. Blue-green algae caused a 12-week closure of Prospect Lake in 2019.

Blue-Green Algae Background
What is harmful algae?
Blue-green algae are a type of bacteria common in lakes throughout Colorado. When conditions are right, blue-green algae multiplies quickly. Those conditions include sustained hot weather, stagnant water, and polluted stormwater runoff.
These conditions result in too much nitrogen, potassium and phosphorus in the water. This causes the harmful bacteria to grow faster than the ecosystem can handle. The increased bacteria harm water quality, decrease the amount of oxygen available to animals living in the water, and can produce a toxin that is harmful to humans and pets.
Blue-green algae are self-limiting, naturally-occurring bacteria, which means it eventually phases itself out of bodies of water.
The Colorado Department of Public Health and Environment (CDPHE) offers additional information about blue-green algae on its website.
