McIntosh Lake


Open to the Public for Limited Use


The lake was called Dawson after John Dawson (1839-1917) before taking the name McIntosh. Dawson joined the Chicago-Colorado Colony in 1871, and farmed east of Hygiene. In 2003, the City leased the surface rights to the lake with the intention of creating a district park which will link Dawson Park, Flanders Park and Boulder County's Lohr Open Space.

Master Plan and Phased Construction

Through a public process, a master plan was developed and approved by Council in the fall of 2003. Phase I of development was completed in 2004. Work included access to the lake for non-motorized boating, parking off Harvard Street and a connecting pathway between Dawson & Flanders parks. Phase 2 completed in 2005 included the soft surface trail construction around the remainder of the lake. Phase 3 construction was completed in 2008 and enhances the habitat along the western and northern shorelines, added a restroom and some picnic facilities. Phase 4 will create a path connection across 17th Avenue/ Hygiene Road.

Shoreline fishing is permitted along the shoreline only at Dawson and Flanders Parks, and from the dam on the south side of the lake. Map showing location of McIntosh Lake in Longmont
