Total storage - 5.22" runoff. The flood pool which is 8 ft. in depth has a discharge rate from 3` c.f.s. to 37 c.f.s. from 18" pipe. During the stormof May 9-10 (both pools were empty except the borrow pit 15.5 iinches of rain full in this watershed and water discharge, for a short time, through the emergeny spillway at a depth of 1.8 ft.

Photograph of break in levee build along State Highway 24 eight miles west of Wayne to protect bottomland field shown beyond.

Photograph of overflow waters for years had destroyed crops on this 30 acre strip of bottomland below Detention Reservoir Nos. 1 and 2 in Owl Creek Watershed. However, intense rains on May 10-11 failed to send creek out of banks. Only damage was from water flowing down fromsloping land at left. Leveridge has farmed the fild for more than 20 yrs. First crops were good, but during wetter years flooding made fundiing here unprofitable. Now Leveridge has plans for developing productivity of field. He has been convinced that land will no longer be subject to annual floodings.
