The Bureau of Reclamation seeks bids for rehabilitation of Red Willow Dam, which has been a concern since discovery of a sinkhole and cracking through the embankment in 2009. Bids are due Aug. 30.

Work is to include excavation of the embankment and toe drain, construction of a filter/drainage blanket, placement of geonet composite on the excavated face of the embankment, construction of a two-stage sand filter and coarse sand drain system, placement of geotextile on coarse sand and gravel drain, construction of a downstream stability berm, construction of a two-stage filter drain in the channel and slopes downstream of the spillway and outlet works stilling basin, repair of portions of the upstream dam face, and construction of a toe drain system with monitoring wells.
The work is expected to cost between $10 million and $25 million.
