Project: Camping on the Battenkill Berm Removal
Location: Downstream of Rte 7A bridge near the confluence of the Batten Kill and Roaring Branch in Arlington, VT.
Time Frame: 2009
Partners: VT Center for Clean & Clear, VT River Management Program, Camping on the Battenkill, VT DEC, GMNF.
Problem Description: A section of berm near the confluence of the Batten Kill and Roaring Branch was directing the force of the current in high water into a high bank opposite. This resulted in substantial erosion and excess sedimentation, which has proven to be damaging to trout habitat. Scientific analysis indicated that allowing more space for the river in periods of ordinary high water would also tend to lessen erosion and flood damage upstream in the Campground.
Project Work Completed: A section of the berm along Roaring Branch about 200 feet long and 8 feet thick was removed. The erosion from the opposite bank has decreased. During the extraordinary flooding from Hurricane Irene in 2011, a massive jam of trees and sediment at the confluence ended up directing water across the Campground with destructive force.
Photos: Photos in the slideshow above show removal of the berm, with the area of large-scale mass wasting evident on opposite bank in background, and two images of the project site post berm-removal and initial replanting of the riparian zone.
