The U.S. Army Corps of Engineers will repair both the left and right side of the plunge pool. Note on the left side of the picture there is no riprap and undersized rip rap on the right side. Both the left and right sides of the pool will be repaired. The pipe is the conduit pipe that outlets the reservoir water into the plunge pool, May 25, 2021.

The U.S. Army Corps of Engineers, Omaha District will be performing maintenance and construction activities Aug. 23 to Nov. 20, at the downstream conduit outlet plunge pools at the following Salt Creek Dam sites: 8 (Wagon Train), 9 (Stagecoach), 10 (Yankee Hill), 12 (Conestoga) and 13 (Twin Lakes); additionally, some downstream maintenance will occur at site 4 (Blue Stem).

Construction will be on the downstream side of the dam and involves removing existing riprap, excavating around the outlet plunge pools, grading, and installing bedding and riprap. The USACE will install a sand drain on the west side of the plunge pool at Wagon Trail, repair minor sloughing (erosion) at the plunge pool at Twin Lakes, and will perform minor grading and re-seeding at Blue Stem near the downstream toe of the dam.

The USACE will lower Wagon Train, Stagecoach, Yankee Hill, and Conestoga reservoirs between 1 to 1.5 feet to facilitate construction activities. Drawdowns will occur between August and September 2021. The project is not considered to be an emergency repair; however, the work is necessary to repair sloughing at the plunge pools caused from high flows.
