Fish Friendly Concrete Structure Installed to Improve Aquatic Organism Passage
The New Sutton Bluff Low Water Bridge - West Fork Black River.
Replace the existing Sutton Bluff Low Water Crossing, which is a barrier to aquatic organism passage, with a fish friendly crossing across the West Fork of the Black River.
The low water concrete box ford at the junction of Forest Road (FR) 2236 and West Fork of the Black River was identified by the Forest Fisheries Biologist as a barrier to the upstream movement of native fish.
Therefore, the existing Sutton Bluff Low Water Crossing was replaced with a new fish friendly low water concrete structure. The new structure reduces water velocity and permits the natural migration and movement of fish and other aquatic organisms up stream during low flow conditions.
The new bridge is designed to be overtopped by water during rain storm events. The bridge does not have a concrete bottom; the stream channel acts as the bottom.
