Photograph of an aerial shot of East Branch Salt Creek Watershed Detention Reservoir #1 and the surrounding area. The back of the photograph proclaims, “East Branch Salt Creek, Wa-No. 1. Detention Reservoir. Drainage area: 1505 acres (613 acres in cultivation; 290 acres in pasture; & 602 acres in abandoned cropland.) Soil units: about 35% #5, deep, medium textured, very slowly permeable & #7, deep, medium textured, moderately permeable; About 65% is #20, shallow medium textured, moderately permeable. General condition is fair. Most cultivated land properly farmed, but grassland need improving. Permanent storage: 2.1 inches. Flood storage: 5.1 inches. Peak flow: 3160 c.f.s. Release rate: 60 c.f.s. About 50 acres of bottomland protected. Estimated flood drainage benefit ratio: 2 to 1. About 262 acres of former cropland has been planted to grass. About 90 acres additional land covered with needlegrass. About 250 acres of severely eroded land now in cultivation needs to be revegetated. Grasslands are generally in a low good condition. Most of the crop lands [sic] are terraced and being handled under conservation farming methods. Some terrace systems need revision.”

Photograph of the formation of a long and deep gully running alongside a road. The formation of this gully came from terraces built ten to twelve years prior, emptying water next to the road. The back of the photograph proclaims, "Terraces emptying into roadside. Terraces built 10-12 years. Has cut road into. Gully ate back as far 100' as much as 25' deep. Has moved fence back 150' to 200' and sodded end are to Bermudagrass."

Photograph of the second year growth of Balck Locust and Chinese Elm trees planted in contour rows for post lot.

Photograph of J. J. Burton, left, discussing the harvest of black locust posts with his tenant, Guy Busser, Jr. , right. 1800 posts per acre were harvested from a 4-acre planting on Soil Unit 9H RP that was inaccessable for farming operations. The plantin was 7 years old at the time of harvest.

Photograph of a portion of a 200-acre field level bordered in the Washita River bottom. This is the first water after leveling and corrugating. Winter oats were seeded and with Nitrogen fertilizer applied, yeilded 80 bushels per acre in 1953. Seeded to alfalfa in 1953 and with 400 lbs of 0-20-0 per acre produced 7 tons per acre. Water supply comes from the Washita River from a unit supplying 4,000 gallons per minute.

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% in 7, deep, medium textured, moderately permeable; & about 8% is 20, shallow, medium textured, moderately permeable. In good condition as result of contolled grazing & good farming practices. Permanent storage: 0. 8 in. Flood storage: 3. 6 in. Peck flow: 535 c. f. s. Release rate: 33 c. f. s. Protects an estimated 25 acres of bottomland. Flood drainage benefit ratio: 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 crop land is under conservation treatment. Grasslands are in excellent condition.
