Photograph of detention reservoir; D.A - 490 acres. Permanent pool - 1.15" runoff with 10.0 acres surface. Flood pool - 4.56" runoff with 29.4 acres surface. Total storage 0 5.71" runoff from 490 acres. Flood pool (10' in depth) discharges through an 18" metal pipe at rate varying from 29 c.f.s. to 38 c.f.s. Both pools were empty but were filled during storm of May 9-10 and 1.0' depth.

Photograph of this 30 acre field of corn was damaged only about 10% during the storm of May 9-10 when 15.5 inchs of rain fell. Without the detention reservoir shown in the background the field would have been a total loss. The reservoir held 5.7 inches of runoff. The normal release, through a 18" pipe, may beseen in the small drain at the right of the corn field.

Photograph of Owl Creek Site #4 after rain of May 9-10. Debris guard around 18" pipe. Notice high water line along dam. Indicated a flow of 1.0 feet through emergency spillway.

Photograph of bottom land protected by this reservoir and by Site No. 1 which is to the right.

Photograph of Owl Creek Site #4. Dentention Reservooir, Drainage area - 300 cc. Permanent pool. 1.13" runoff with 6.88 surface acres. Flood pool - 4.09" runoff with 19.50 surface acres. 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 farmer L.J. Key and SCS Technician Harry Maricle lift a section of dried sediment from a field on which Key had a good stand of cotton before the May 10-11 rain storm. Twenty-two acres of this land in 1949 produces 34 bales of cotton. Key, when photo was made, was harrowing to dry out field to replant. Approximately 100 acres here were covered by sediment from 1 to 12 inches deep.

Photograph of Walter Gray, left, tells SCS Engineer Harry Miricle of efforts to prevent flooding of rich fields through straightening of Finn Creek channel and building levees. Says 30 years ago a small bridge crossed creed neart this point. Five years agoa a dragline on the straightening project tore into the bridge structure. It was nine feet below the surface of the field.

Photograph of Burnett who observed at 6 am on morning of May 11 water coming over spillway of dam which is partly visible at upper right. Rainfall had been most intense during early hours. Water continued to flow over spillway until later morning. Burnett here suveys with satisfaction his undamaged water gap fence which each year previously he had been forced to replace after floods.

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.

Photograph of aerial view of fifteen houses that were washed from their foundations during flood of May 9-10, 1950. Some of the houses drifted two blocks.

Photograph of bridge (on rier) on reenforced concrete piles was overtopped by flood waters. Several of the pilings failed by shifting downstream.

Photograph of view looking up-stream through break in embankment. Water still flowing through break. Note washin in topsoil on down-stream slope of the embankment.

Photograph of view looking up-stream through break in embankment. Inflow from up-stream temporarily blocked and break partially drained.

Photograph of view looking down-stream through break in embankment. Failure occurred on night of May 9th. High water mark 4.9 feet above inlet to draw down tube.

Photograph of Harry Maricle, SCS Engineer, pointing high water mark after 10-11 May rainfall on Owl Creek Detention Reservoir #5. The back of the photograph proclaims, "SCS Engineer Harry Miricle [sic] shows high water mark during operation of Owl Creek Watershed #5 after May 10-11 rainfall of about 15 inches."

Photograph of an aerial shot of the destruction left behind after the flood of May 9-10, 1950 at or near Willow Creek. Several houses affected by the flood. The lack of homes in the lower center of photograph indicates the former presence of fifteen homes that were washed from their foundations and drifted up to two blocks away. The back of the photograph proclaims, "Fifteen houses were washed from their foundations during flood of May 9-10, 1950. Some of the houses drifted two blocks."

Photograph of submerged 18-inch corrugated metal outlet pipe in operation. The back of the photograph proclaims, "Submerged 18" corrugated metal outlet pipe operating with 2.2 ft. over inlet riser or 18.45 ft. total head. (Approximately 33 c.f.s.)

Photograph of water discharging from corrugated metal pipe from Owl Creek Site #5. The back of the photograph proclaims, "Owl Creek Site #5. Discharge from corrugated metal pipe operating at 35 c.f.s. (7. 2 ft. over drop inlet weir or 21.41 ft. total heed.) Photograph taken May 13, 1950 after storm of May 9-10. Discharge is into naturally formed still pool from above tail-water surface."
