Union Reservoir Interim Trail
A public meeting was held on Tuesday, April 24th, 2012 to gather input on opportunities, constraints and potential issues that should be considered during the design of the trail project. Staff is incorporating the input in the scope of work for potential design consultants for the trail. The City intends to have a design consultant on board by early August. Below is a summary of the meeting and DRAFT timeline for the project.
If you have any questions regarding the Interim Trail Project, please contact Kathy Kron, Project Manager at (720) 774-4528 or via e-mail at kathy.kron@ci.longmont.co.us.

Union Reservoir Recreational Master Plan
A recreational master plan study began in 2007 but was never adopted. Conditions changed at and around the reservoir including City purchase of lands on the western side of the reservoir. Public meetings were held in 2011 and was adopted by City Council on February 14, 2012. Link to Union Reservoir Master Plan Report
Union Reservoir is a 745 acre body of water providing many outdoor recreational activities. Originally called Calkins Lake, the reservoir was carved out during the last glacial age and is one of only a few natural lakes in Colorado. In 1903, the Union Ditch Company began drilling a tunnel to release water into the St Vrain River. According to Colorado water law, that made Union a true reservoir. Today, visitors to Union Reservoir can enjoy fishing, swimming, wakeless boating, camping, windsurfing and picnicking. The Reservoir is located approximately 7 miles west of I-25. For additional information, call Ranger staff at (303)772-1265.
Union Reservoir Recreational Master Plan Approval
City Council approved the Recreational Master Plan at their February 14, 2012 meeting. Approval included the requirement to continue to meet with neighbors to discuss the design of the planned loop trail, bring that design back to the Parks and Recreation Advisory Board and to City Council prior to detailed design.
Meetings with neighbors are currently planned or underway. If you are interested in participating in the design of the loop trail, contact Paula Fitzgerald (information on left side of this web page).

Project Information
Changed Conditions
Since the time of the 2007 Draft Recreational Master Plan many conditions have changed including:
- City land purchases on the west shoreline properties (Adrian and Bogott)
- West Union development no longer planned for the area
- Sale of Open Space Bond funds which could be used for some improvements
- 2010 Special Events on lands south of the reservoir (HeavenFest and Kinetics)
- Town of Firestone annexation of nearby lands
- Drop-off in camping demand at the reservoir (likely from improvements to camping facilities at the nearby St Vrain State Park)
- Environmental study update for the reservoir
Environmental Update
Walsh Environmental Consulting updated the previous environmental work that was utilized for the 2007 Master Plan. Highlights of the new report include:
- 4 state listed species with potential or current habitat on or near the reservoir
- Bald Eagle – potential habitat, species of concern (confirmation that the Eagle uses the reservoir as a hunting area and trees as perches)
- Burrowing Owl – potential habitat (none found in 2011 survey), threatened species
- Northern Leopard Frog – potential habitat, species of concern
- Black-tailed Prairie Dog – present at the reservoir (2 colonies), species of concern
- No major changes to wetland areas or habitats
- Walsh provided comments on the 2011 revised draft Master Plan with the following highlights:
- Use native plants for landscaping
- Use fencing as well as signs to keep people and dogs out of sensitive areas
- Provide a bird blind for wildlife viewing
- Protection of an existing Osprey nest on eastern shoreline
- Do site specific wildlife management and prairie dog management plans

Reservoir Enlargement Study
The Union Reservoir Enlargement Study is a separate project but the future shoreline is reflected in the Recreational Master Plan. This study estimates an increased surface area of the reservoir by approximately 26% - 33% depending on final configuration of the enlargement. More information on the Enlargement Study can be found here:

Project History
The City of Longmont Natural Resources Division began the Union Reservoir Master Plan project in 2007 with a large amount of public input. Highlights of the Reservoir history include:
- 1986 – City of Longmont purchased controlling interest in the reservoir company and files an enlargement decree for future reservoir expansion
- 2005 – West Union development enters City of Longmont annexation process. Council directs staff to begin a comprehensive planning effort for the Union Reservoir surrounding properties including parks and recreation.
- 2007 – The Parks and Open Space Division conducts a 6 month recreational master planning effort, concluding in December with an update to Council.
- 2008 – The 2007 draft Union Reservoir Recreational Master Plan is put on hold.
- 2009 – City purchases 2 properties formally part of the West Union development (Adrian and Bogott). Open Space bond funds are sold providing money for improvements at the recreational area among other projects. HeavenFest and Kinetics Conveyance festivals took place at or near the reservoir.
