The upstream dam slope is being extended into the reservoir interior by approximately 17 feet. The dam embankment widening is approximately 875 feet in length. The borrow area for the The dam embankment on the northwest and north side of the reservoir will have the interior (upstream) slopeexcavated down to bedrock and stockpile for reuse. The remainder of the fill for the dam embankment soils shall come from the borrow area. Dam embankment soils shall be moisture conditions, mixed and compacted for each 8-inch loose lift which are to be tested. Existing riprap will be removed from the dam and stockpiled for reuse. The riprap will be placed at 24-inch thick perpendicular to the slope. The existing riprap bedding will be stockpiled for borrow area backfill. A two-foot-deep cutoff key will be constructed into the bedrock. The key will vary from 15 feet to 25 feet wide, depending on the elevation of the key cutoff. Additionally, a one-foot-thick clay blanket will be constructed 25 feet from the upstream dam toe, which transitions to a two-foot-thick clay blanket in the northeast corner of the reservoir near the existing outlet works structure which will be constrained by a new cast-in-place reinforced concrete wall.
