Description of Existing Auxiliary Spillway

The following description of the existing auxiliary spillway at Devil’s Kitchen Dam is provided for general information only and in no event is this information considered as a bases of accurately representing all relevant features of the auxiliary spillway needed to complete the modification to the spillway. Bidders shall make their own investigations of existing conditions, and if they do not do so, the Government will not be responsible in any way for the consequences.

The auxiliary spillway is an overflow structure controlled by an earthen berm with a crest elevation of 513.0 feet and a crest length of 419 feet. The berm has a top width of approximately 3 feet and 3:1V upstream and downstream slopes. According to the available as-built drawings for the auxiliary spillway, a portion of the berm was placed on 18-inches of riprap. The bottom of the upstream slope of the berm is also armored with 12-inches of riprap on 6 inches of filter base course.

Immediately downstream of the earthen berm is Tacoma Lake Road, a two-lane County road.

The reinforced concrete roadway is 24 feet wide. The available as-built drawings show a roadway slab thickness of 2 feet. There is are cutoffs on the upstream and downstream side of the road to a depth of approximately 5 feet and 8 feet, respectively. According to the drawings, the road is reinforced by #6 bars. The area immediately downstream of the road is lined with riprap, which was placed on a 6-inch layer of crushed stone on top of 6 inches of filter base course. The riprap was placed to a depth of 8 feet immediately downstream of the road and the depth of riprap gradually gets shallower to a termination approximately 30 feet downstream of the road. A photograph showing the auxiliary spillway berm and reinforced-concrete road is presented on Figure 1. As-built drawings showing the plan and sections of the auxiliary spillway are presented on Figure 2.
