Location: Seven Lakes, NC

Lake Auman project was to reconstruction the emergency spillway on an existing Dam. The existing spill way was sand material and was to be replaced with Articulated Concrete Block. A porta dam was needed to hold back existing water to grade for the turn down for the ACB matting and install concrete anchoring. After matting was place with a crane and concrete poured on anchoring channel riprap was placed in future water line. Upon completion the dewatering pumps were shut down and water equalized behind porta dam and then porta dam was removed from lake. At this time, the crest ACB and down slope ACB was placed. TRM matting was place on down slope side and upon completion TRM mat, three rows of A-Jacks were place. The A-Jacks act as a dissipator if water every crest the emergency spillway.
