West Fork Beaver River, West Point, OH. Constructed Sept Minimal height Bendway Weirs in a gravel-cobble-sand-silt bed stream for thalweg realignment & bank stabilization in the area of an exposed high-pressure pipeline overbend.

Lisbon Inn State Route 154, Lisbon, OH

Functions of Bendway Weirs on the West Fork Beaver River: Main functions of the BW are to provide bank stabilization within the bend and realign the thalweg through the bend and center the thalweg where the pipeline overbend was exposed by erosion. The pipeline was directly protected with Submar’s patented Articulated Concrete Mattress (ACM) system.

SUB MAR Great aquatic habitat due to the deep pools created by the Bendway Weirs. These pools were full of high quality fishes, indicating that water quality is excellent. {5 years after project completion} Pix by derrick
