U.S. names South Dakota firm to repair Richland Dam

CHADRON, Neb., U.S. 10/20/11 (PennWell) — The U.S. Forest Service has named a South Dakota company to perform civil construction to repair Richland Dam in the Nebraska National Forest in South Dakota.

The Agriculture Department agency took bids in September from small businesses to repair Richland Dam, which was built in 1938 in Jones County, S.D., for waterfowl habitat, wetlands, and fisheries.

RP&H Inc. of Reliance, S.D., received the $490,828 contract to correct problems including failure of the dam’s primary spillway conduit as well as erosion occurring along the entire dam face and the overflow spillway channel.

RP&H is to remove and replace outlet pipe and inlet, construct a plunge pool below a new outlet pipe discharge, place rock riprap, and construct a maintenance vehicle trail across the dam. The work is to require 120 days.
