Future Plans

McIntosh Lake is currently being developed as a master-planned Nature Area.  

Master Plan Development
Phase 4 of the master planned Nature Area project included analysis of appropriate pedestrian crossings of 17th Avenue. This project identified appropriate at grade, and / or grade separated crossing areas west of Hover Road. Linkages between schools, parks (including McIntosh Lake), the future St. Vrain Greenway trail (at Airport Road) and residences north and south of this arterial road are desired. The design has been completed.

Phase 3 of the master planned Nature Area project was constructed in 2008 - primarily including native re-vegetation at the west end of the lake as well as installation of a new restroom. 

Phase 2 construction began in early 2004 and completed the trail loop (3.5 miles) around the entire lake perimeter. The trail also includes a spur trail to Boulder County's Agricultural Heritage Center located off Hwy 66. Rules and Regulations signs are posted and temporary boat ramps were installed. Boat buoys delineate the wildlife area in the north west portion of the lake as shown in the Master Plan. On May 15, 2004, Lake McIntosh was opened to the public.

Phase 1 construction, completed in 2003, provided a concrete trail connection between Flanders and Dawson park sites along the eastern edge of the lake as well as a new trailhead parking lot for the Nature Area site off Harvard Street.
