Plans set to implement Irwin Run Culvert removal

From staff reports

The U.S. Department of Agriculture, Forest Service is planning to implement the 2022 decision to remove a large culvert on Irwin Run associated with the abandoned Clarion River Railroad in Allegheny National Forest.

The culvert is upstream of the bridge on Route 3002, which crosses Irwin Run. Removal of the culvert will restore the natural stream bed, which will improve aquatic organism passage, the stream channel and floodplain functions, according to the Forest Service, which has partnered with Trout Unlimited to remove the culvert and complete the stream restoration.

Work to clear the trees was scheduled to begin earlier this week. Earth work for the culvert removal and stream restoration is anticipated to begin Tuesday and is expected to be concluded by Oct. 13.

After the culvert removal, trees and shrubs will be planted along Irwin Run to help restore the site.

Eventually, upstream of the culvert, stream habitat improvement work will be completed along 4.9 miles of Irwin Run and its tributaries, the Forest Service said. The work will benefit a cold-water fishery with natural wild trout reproduction as well as salamanders, frogs, crayfish and other wildlife that travel along stream corridors.

Additional information on the decision can be found at fs.usda.gov/project/?project=60626.
