Griffy Lake is a small reservoir in the north of Bloomington fed by Griffy Creek. Canoe rental is available at Griffy Lake Nature Preserve, a Bloomington city park.
Griffy lake was formed by the construction of a dam in 1924. The reservoir served as the principal source of water for Bloomington until 1953. As an emergency source of water it is owned by the City of Bloomington Utilities, although the Parks & Recreation Department operates the lake and surrounding areas.
