Specifications include, but are not limited to: The proposed modifications to the Bullock Pen Lake Dam include the construction of a 12-cycle, 260-foot wide reinforced concrete labyrinth spillway with a stepped chute over the dam embankment. The proposed spillway is sized to safely pass flows from storm events up to the PMP. Modifications also include raising the crest of the dam to elevation 770.3 feet, providing internal embankment drain and filter systems, re-grading the upstream and downstream slopes of the existing embankment to match the existing slope angles of 3H:1V and 2.5H:1V, respectively, addressing historic seepage issues in the existing spillway, and closure of the existing spillway and spillway outlet channel. In addition to these modifications, the existing low-level drain pipe will be filled with grout and abandoned. A siphon, consisting of a 24-inch diameter high-density polyethylene (HDPE) pipe, will be installed at the left end of the proposed spillway and will serve as the new low-level drain. Miscellaneous site improvements, such as drainage improvements and the construction of permanent site access roads, are also proposed.
