Photograph of erosion control measures on a cultivated field. This field was formerly farmed with straight down hill rows and the soil suffered badly from silting. Terraces and grassed channels have been constructed and contour cultivation is now practiced. A volunteer crop of wheat serves as winter cover and supplemental pasture for livestock.

Photograph of gully control by diverting wter, sloping banks and planting trees. This area was formerly a huge gully caused by unprotected diversion ditch. An area has been fenced out of pasture. Gully banks sloped, diversion terrace constructed and cottonwood and black locust trees planted. Erosion is 100% stabilized and trees show good growth. Geary, Okla. CCC Camp

Photograph of erosion caused by unprotected farmer terrace outlets and road ditch run-off. Field on the left has been terraced for 8 to 10 years. Terraces had too much fall. Roadside ditch will be sloped and added with Bermuda grass. Road graded and field on left will be terraced to conform with standard grade and land slope as recommended by SCS. OK-8087

Photograph of a Bermuda grass sodder designed and constructed by a farm operator, Mr. Kerr, shown in the photograph. OK-8064.

Photograph of masonry drop structure for gully control, terrace outlet channel. Masonry structure was built in later 1937 in natural wash, badly gullied, to accelerate silting for erosion stabilization. Outlet channel on the right is now well-vegetated, providing a safe waterway and the former active erosion behind the structure is almost 100% stabilized. OK-5969-B.

Photograph of CCC Enrollees helping to construct a wooden concrete form for making a watering trough. Okla-8062.

Photograph of gully control in a natural drain, formerly 15 foot to 20 foot deep. Soil Conservation sloped banks, made fills and solid sodded to Bermuda grass. Approx. 700 acres drain through this outlet and erosion is almost 100% stabilized. May to August 1940 this outlet safely carried run-off from a total of 25 inches of rainfall.

Photograph of a Marsh Hawks Nest (Circus hudsonius) located in tall grasses of a draw in a mixed-grass pasture, which has been "rested" for 5 years. 11 pellets picked up from around the nest and analyzed by Denver Laboratory of U.S. Biological Survey were composed as follows: 3 cotton-rat (Citellus 13-lineatus), 1 house mouse (Muz musculus), 1 horned-lark (Otocoris), and 1 mouse (Mus) and bird (sparrow?). Original Negative size 9 x 12 cm.

Photograph of a Marsh Hawks nest (Circus hudsonius). This nest is located in tall grasses of a sraw in a mixed-grass pasture, which has been "rested" for 5 yrs. 11 pellets picked up from around nest and analyzed by Denver Laboratory of U.S. Biological Survey were composed as follows: 3 cottontail (Sylvilagus), 3 cotton-rat (Sigmodon hispidus), 2 ground-squirrel (Citillus 13-linsatus), 1 house mouse (Mus musculus), 1 horned lark (Otocoris), and 1 mouse (Mus) and bird (sparrow?).

Photograph of a Marsh Hawks nest (Cirens budscaius). This nest is located in the tall grasses of a draw in a mixed grass pasture which has been "rested" for 5 years. 11 pellets picked up from around nest and analyzed by Denver Laboratory of this Biological Survey were composed as follows: 3 cottontail (Sylvilagus), 3 cottonrat (Signoden hispidns). 2 ground squirrel (Citellus 13-lineatus), 1 house mouse (Mus musculus), 1 horned lark (Otocoris), and 1 mouse (Mus), and bird (Sparrow?).

Photograph of the sprig sodding of Bermuda grass on retired land. Works Progress administration [WPA] labor is utilized in sodding as cooperator covers furrows with a go-devil sled. 4% slope. Dougherty very fine sandy loam soil. Ok-8067.

Photograph of highway erosion control project. Unsafe bridge eliminated and drop inlet constructed (Hwy Comm., WPA and SCS cooperating) to allow deep gully to silt in, thus stabilizing erosion.Stock will be also be watered here as water gathers in basin.
