Spanning 245 acres, Sauk Trail Reservoir in Frankfort protects wetland habitat along a portion of Hickory Creek while serving as a regional stormwater management facility.
The site includes a dry reservoir and dam designed to hold water during flood events. This dual purpose supports both public safety and the surrounding ecosystem.
Exploring the preserve
Sauk Trail Reservoir features 0.93 mile of paved trail, ideal for biking, hiking, running, in-line skating, cross-country skiing and snowshoeing. Because the trail is constructed on a flood control structure, visitors are required to stay on the trail, and the preserve may be closed during times of flooding.
Flora and fauna
Sauk Trail Reservoir protects wetland habitat that supports a variety of plant and animal life.
Ongoing management — including prescribed burning — helps maintain and enhance these natural resources.
Preserve history
Sauk Trail Reservoir was acquired between 1976 and 1978 in partnership with the State Division of Waterways for the construction and operation of a stormwater management facility.
The preserve is part of the Hickory Creek preservation system, which protects nearly 1,800 acres.
