Photograph of an aerial shot of Owl Creek Detention Reservoir site #1 and the surrounding area. The back of the photograph proclaims, “Owl Creek Ok-SCD-13-Wa.2. Site #1. Detention Reservoir. Drainage area – 500 acres. 81.0 acres in cultivation; 334.0 acres in pasture, range, woods; 85.0 acres in abandoned cropland – revegetated. Excellent cover on grassland provides silt screen for water from cultivated land. Note all cultivated fields were terraced when picture was taken. Permanent storage: 1.10. Flood storage: 4.18. Peak flow: 900 c.f.s. Release rate: 23 c.f.s. Detention reservoir protects 700 acres. Flood drainage benefit ration 66:1. Note farm ponds on main branches of drain above this reservoir. Others are planned. White arrows appearing in foreground mark each end of dam at center line. Arrows laid out & ground covered with lime slurry.”

Furthermore, a small house stands next to the road in the upper left. The back of the photograph proclaims, “Ok-SCD-13-Wa.2 – Owl Creek Detention Reservoir Site #4. Redish [sic] Prairie Land Resource group. 70 acres in cultivation, 220 acres in pasture, range, woods; 10 acres in abandoned cropland. Excellent cover on grassland. In foreground abandoned cropland has been revegetated. At right geological erosion has been greatly retarded by good grass and controlled vegetation. Permanent storage: 1.13 in. Flood storage: 4.10 inches. Peak flow: 490 c.f.s. Release rate: 12 c.f.s. Acres of bottomland protected: 700 acres. Flood drainage benefit ratio: 6.6/1. Near top of photo the main drain appears to continue up (north) and beyond the field of the camera. Actually this drainageway drains in the opposite direction startin [sic] ¼ from top of photo.”

Photograph of aerial view of East branch Salt Creek, Wa 1. Drop Inlet. Drainage area: 235 acres (200 acres in cultivation, 28 acres inpasture & 7 acres in abandoned cropland). Soil Units: About 75% in 5, deep, medium textured, very slowly permeable, about 17% is 7, deep, medium textured, moderately permeable, & about 8% is 20, shallow, medin, textured, moderately permeable. It is in good condition as result of controlled grasing and good farming practices. Permanent storage: 0. 8 in. flood storages 3. 6 in. Peak flow: 535 c. f. s. Release rates 33 c. f. s. Protects about 25 acres of bottomland. Flood drainage benefit ration: 1 to 1. Most of this drainage area is from very gently sloping cropland which is farmed to small grains. About 1/2 of this cropland is under conservation treatment. Grasslands are in excellent condition.

Photograph of aerial view of watershed: OK-SCD-20 Wa #5, Site #3. Type of structure: Drop inlet. Drainage area: 160 acres. Soil units: Deep medium textured slowly permeable and permeable. Area in cultivation: 32 acres. Area in pasture: 12 acres. Area in abandoned cropland: 116 acres. General condition of drainage area: Poor cover, sheet and gully erosion. Note: Right edge shown Site #2 on Adolph Johanson farm. Type of structure: Drop inlet. Drainage area - 15 acres (4 acres in pasture, 11 acres in abandoned cropland). General condition of drainage area: Poor cover, serious gully & sheet erosion. It protects detention reservoir #1 & bottomland from silt. See pipe installed in third gully from right edge.

Photograph of Bob Moore of Edna, Kansas, a temporary Employee of the Soil Conservation Service, spreads bluestem seed out to dry on the floor of the airport hanger in Coffeyville, Kansas. All this seed was cut in the vicinity of Nowata, Oklahoma. It had to dry several days before it could be stored permanently in sacks. OK-9735.

Photograph of Secrest Ranch showing the rear view of a self-propelled combine cutting seed from Indiangrass and big bluestem. Yields here were around 250 pounds of seed to the acre. The native grass is to be used largely in the Washita River watershed. OK-9756.

Photograph of a close-up showing how exactly soil blows as William Trarel sifts it through his fingers. This is a lower part of a 65-acre field of cotton, grain sorghum and sudan grass that washed out in 19 inches of rain on June 22, 1948. Silt deposited in the lower part of the field has created a blow problem. OK-9657.
