About Coot Lake

Coot Lake is a scenic natural area with fishing, walking and jogging opportunities while experiencing nature. It is about 1.2 miles around the lake.

Algae Bloom Notice

If you see algae in lakes and ponds, take extra precautions to avoid contact with the water , because some algae blooms can be harmful to people and pets. Algal blooms can contain cyanobacteria –often referred to as blue-green algae. While the vast majority of algae often seen in ponds and lakes during summer months are not toxic, cyanobacteria can produce toxins, which can be harmful to dogs and humans at elevated levels.  More information

Nature Play Opportunities

Children have a wide variety of unique nature play opportunities at Coot Lake. A portion of Coot Lake is a wildlife reserve for wetland species, which provides ample opportunities for children to observe local species as well as to fish in other designated areas. The 1.2-mile trail around the lake has access to various short trails and the Boulder Reservoir and contains an art walk. The art walk displays prints of scenes and quotes from the lake that children may stop by and read during their walk around the lake. The art walk brings a new and creative perspective to the trail.

Carter Lake Pipeline Project

Major construction on the Carter Lake Pipeline (also known as the Southern Water Supply Project II) has been completed. Ongoing activities near and around Coot Lake and the Boulder Reservoir are focused primarily on site revegetation and restoration.

The Northern Colorado Water Conservancy District (Northern Water) is managing the project on behalf of the participants: City of Boulder, Berthoud, Left Hand Water District and Longs Peak Water District. 

 

 

Wetlands Mitigation 

Alternate Route around Coot Lake

 

Directly related to the Carter Lake Pipeline project, the City of Boulder Utilities Department has constructed additional infrastructure at the 63rd Street Water. Per the City wetlands permit received for this construction, additional wetlands mitigation is required. Areas around Coot Lake have been identified to remove non-native vegetation and plant native species to improve the local ecosystem. Tree removals will occur May 4-8, 2020, and the remaining mitigation work will be completed throughout May 2020. The trail around Coot Lake may experience intermittent closures to ensure safety of visitors and an alternate route has been identified. Closures will be signed and personnel posted to ensure visitors remain away from heavy equipment.
