McIntosh Lake

McIntosh Lake offers 3.5 miles of easy walking trails and beautiful views of the Rocky Mountains, most notably Longs Peak and Mt. Meeker. It’s also a great area to see prairie dogs, bald eagles, pelicans and other wildlife. McIntosh Lake is a reservoir and as such is part of the statewide ditch and reservoir system. Each year, the water level in Lake McIntosh is dependent on system-wide priorities and weather factors such as snowpack and precipitation.

Dawson Park borders McIntosh Lake on the northwest side of Longmont. It was named in 1973, after John Dawson (1839-1917), and developed in 1981. Dawson joined the Chicago-Colorado Colony in 1871, and farmed east of Hygiene, Colorado. The lake was called Dawson before taking the name McIntosh. With commanding views of the mountains, this 15 acre park offers shoreline fishing, tennis, and a restful walking trail system. Dawson Park adjoins the McIntosh Lake District Park which also links to Flanders Park and Boulder County’s Lohr Open Space and Agricultural Heritage Center at Lohr-McIntosh Farm.
