Photograph of an aerial shot of Owl Creek Detention Reservoir site #1, spillway, and the surrounding area. The back of the photograph proclaims, “Owl Creek Site #1. Detention Reservoir, D. A. – 500 acres. Permanent pool – 1.03” runoff with 12.3 acres surface. Flood pool – 4.19” runoff with 33.8 acres surface. Storage total – 5.22” runoff to emergency spillway. The flood pool, which is 8’ in depth, discharges through an 18” pipe at an average rate of 27 c.f.s. or at an average rate of 1.3 inches runoff per day for its whole drainage area. During the storm of May 9-10, 15.5 inches of rain fell upon this watershed. Runoff filled the flood pool to the emergency spillway shown in foreground. In this photo flood pool is still discharging with 2 ft. of water over the 18” discharge pipe.”
