Robinson Dam is a dry-stone masonry and earth dam which was constructed around 1838. The dam has a maximum height of 15-feet and is approximately 850 feet long. It is comprised of a 500-foot long, 4-foot high earth dike section on the north and 350-foot long, 4-to 15-foot high, dry-stone masonry and earth dam section on the south. These sections are separated by a 10-foot wide by 3.5-foot high mortared stone masonry spillway which discharges into a 7-foot high by 2-foot wide sluiceway. Generally the dam is considered to be in poor to fair condition. However, there are several visible signs of distress which indicates a potential hazard at this site bulging of the stone wall on the downstream face of the dam, uncontrolled discharge through a blocked outlet conduit, slight-to-moderate seepage at the downstream toe of the dam, erosion on the upstream face of the dam, accumulation of debris in the spillway channel, and recent unauthorized filling of the dam crest. An inflow test flood of 1,250 cfs one-half of about 1.0 feet.
