Reclamation last sought bids for the work in June, which includes: installation of soldier piles on the left side of the spillway and excavation on the left and right sides of the spillway; demolition of the parapet wall atop the dam and portions of the concrete spillway; jet grouting beneath the crest structure; installation of drains and filter material; construction of new crest structure and parapet wall; installation of low-voltage electrical distribution equipment; refurbishment of four gate hoists and four 18- by 17-foot spillway radial gates.
