Photograph of an aerial shot of Owl Creek Site No. 1 Detention Reservoir and the surrounding area. The back of the photograph proclaims, “Owl Creek OK-SCD-13-Wa. Site No. 1. Detention Reservoir. This photo was taken when heavy rains of May 18 reached peak flow at this reservoir, which was empty before rain. Water filled permanent pool and rose 30 inches above lip of draw-down pipe. Flood land below would have flooded but for Detention Reservoir.”

Photograph of the aftermath of May 10-11 flooding as Finn Creek waters crossed this bottomland field, deposited sediment, washed out the young corn, broke the dikes protecting cropland, and took out a half mile of fencing along roadway. The back of the photograph proclaims, "On May 10 and 11 waters from Finn Creek crossed this bottomland field, depositing sediment and washing out young corn. Dikes protecting cropland has broken, unable to carry water after intense downpour. Water took out half mile of fencing along roadway."

Photograph of an UNIDENTIFED man (Walter Grey) surveying damage from a broken levee, which damaged 450 acres of bottomland and severely damaged 100 acres. The back of the photograph proclaims, "Owner Walter Gray reports spending $35,000 on levees to protect his bottomland over a 20-year period. Large breaks in levees, along straightened creek, can be seen across field. Owner Gray said 450 acres of bottomland were damaged by flood. Over 100 acres were damaged seriously."

Photograph of the construction of a floodwater retarding structure on the Jim Dulin Farm near or on Site No. 5, Owl Creek Subwatershed of the Washita River. The back of the photograph proclaims, "Floodwater Retarding Structure Construction, Site No. 5, Owl Creek Subwatershed of the Washita River. Inlet to drawdown structure with anti-vortex baffle and debris guard in place, showing the sluice gate in the open position at bottom of riser and the weir at the top of the riser."

Photograph of water discharge from a corrugated metal pipe extended from Owl Creek Site #5. The back of the photograph proclaims, "Owl Creek Site #5. Discharge from corrogated[sic] metal pipe operating at 35 c.f.s (7.2o over drop inlet weir or 21.41' total head). Discharge is into naturally formal still pool from above tail-water surface. Photo taken after flood of May 9-10."

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 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 farmer Dick Long pointing to the high water level reached during the May 10-11 downpour on Owl Creek Detention Reservoir #4 to Engineer Harry Maricle. People shown in photo go as followed from left to right: 1. Dick Long, 2. Harry Maricle. The back of the photograph proclaims, "Farmer Dick Long pointing to high water level reached during downpour of May 10-11. Rainfall total was approximately 15 inches in 30 hours. Eighteen-inch draw down pipe ran 90 hours. Water ran over spillway short time. Engineer Harry Maricle, shown with Long, estimate capacity of reservoir filled two and one-half times in 72-hour period. Sloughing of sod protection in one place caused residents to fear dam might break during storm. Long. Who worked on such dams, told them: "Those dams will be there when we are all gone."

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.
