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.”

Photograph of the failure of flood prevention dam No. 13. Looking upstream along outlet structure. Failure occurred when water rose approximately 4 feet above riser, or 6 feet below emergency spillway. Dam completed in January 1957, failure occurred during storm of May 18th.

Photograph of 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 were damaged seriously.

Photograph of Self Estate 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 Owl Creek site # 5. Discharge from corregated metal pipe operating at 35 c. f. s. (7. 2 ft. over drop inlet weir or 21. 41' total head). Discharge is into naturally formed still pool from above tail-water surface. Photo taken after flood of May - 10.

Photograph of aerial view of slight damage to newly sodded spillway after 12" flow, following 15. 5" rain of May 9 -10.

Photograph of looking south along Owl Creek Detention Reservoir No. 1. Water is now at permanent pool level. On May 11 after 30 hours of rainfall, totaling nearly 15 inches, water reached spillway level but did not flow through spillway. Conservation treatment and condition of range in drainage area believed reason acre runoff did not reach proportions of that on Dams 4 and 5.

Photograph of aerial view of Owl Creek Site #4. 1. 8 ft. of water flowed through this spillway with only minor damage although the Bermuda sod on it has just started to grow.

Photograph of flood prevention dam. Failure of flood prevention dam no. 7. Soil washed away from outlet structure. Dam was completed March 1957. Failed May when water was approximately 0. 5 foot above crest of emergency spillway.

Photograph of failute of flood prevention dam no. 13. Looking upstream along outlet structure. Failure occurred when water rose apporximately 4 feet above riser, or 6 feet below emergency spillway. Dam completed in January 1957, failure occurred storm of May 18.

Photograph of Owl Creek site #5. Discharge from corregated metal pipe operating at 35 c. f. s (7. 2 ft over drop inlet weir or 21. 41 ft. total hend). Photo taken May 13, 1950 after storm of May 9-10. Discharge is into naturally formed stilling pool from above tailwater surface.

Photograph of aerial view of Owl Creek Site #5. This 30 acre field of corn was damaged only about 10% during the storm of May 9 - 10 when 15. 5 inches of rain fell. Without the detention reservoir shown in the background the field would have been a total loss. The reservoir holds 5. 7 inches of runoff. Theh norm release, through an 18" pipe, may be seen in the small drain at the right of the corn field.
