Abstract
Middle Creek Dam is an earthfill, sheetpile and concrete structure with a total length of about 500 feet. The height of the dam is 18 feet above the streambed with the maximum height of embankment being 10 feet above natural ground. The center half of the structure is a 250 foot long spillway and control structure constructed of two parallel lines of sheetpiling retaining a zoned fill and is capped with concrete. The 15 feet wide control structure is accessible from the left abutment by a walkway. The structure contains a minimum flow sluice gate and a 18-inch by 36-inch drawdown sluice gate. The downstream area, below the vertical drop weir, is protected with an 18-inch thick concrete slab. The spillway is connected with concrete cutoff walls on top of sheetpiles to the earth embankment at the abutments. The top of the dam is 4.0 feet above weir crest.
