Tips for birding Kirwan Reservoir
When the water level at the reservoir is low, the east and west sides of Knapp Road near OH-14 become outstanding mudflats that are great habitat for migrating shorebirds. A scope is recommended, and there is a pull-off for limited parking.

About West Branch State Park
West Branch State Park in Portage County is situated on the glaciated plateau of northeastern Ohio. Although the land was uplifted as part of the Appalachian Mountain building process, the glaciers were able to override the gentle hills of the plateau. Huge ice blocks broke free from the glaciers and kettle lakes formed as the blocks melted. Eventually, these lakes filled with sediment leaving boggy wetlands with unique assemblages of plants. The West Branch area contains numerous bogs filled with buttonbush, alder, skunk cabbage, and swamp white oak.
Another natural feature of the park is the stand of beech-maple forest. In pioneer times, the beech-maple belt in Ohio was very extensive and stretched across the plateau from Mansfield to Pennsylvania. These woodlands harbor a variety of plant and animal life. Woodland wildflowers such as Dutchman’s breeches, bloodroot, and trillium are found here. Red fox, skunk, opossum, and raccoon find the park’s habitat suitable. Songbirds occupy the leafy canopy of the woodlands while waterfowl and shorebirds dabble in the reservoir.

About Michael J. Kirwan Dam and Reservoir
Authorized by the Flood Control Act of 1958, the Michael J. Kirwan Dam and Reservoir is one of 16 flood control projects in the Pittsburgh District. The project provides flood protection for the Mahoning River Valley and the Beaver and upper Ohio River.
Since its completion in 1966, the Kirwan Reservoir has prevented flood damages estimated to be in excess of $755 million. Kirwan has the capability to store the equivalent run-off of 18.35 inches of precipitation from its 80.5 square mile drainage area. When compared, the $20 million cost of construction is far outweighed by the project’s flood prevention benefits.
Kirwan also stores water for release downstream during dry periods. This has the effect of improving both the quality and quantity of flow in the Mahoning River for domestic and industrial use, recreation, aesthetics and aquatic life.
