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 class VII land consisting of rough broken land. The river channel in the background is class VIII land consists of river wash.

Photograph of a follow-up picture of Okla-5969 of the progression of a Masonry arch drop in stabilizing gully erosion. The back of the photograph proclaims, “Masonry Arch Drop, Gully Control Terrace Outlet Channel. Masonry structure was built latter part of 1937 in natural wash, badly gullied, to accelerate silting for erosion stabilization. Outlet channel on right is now well vegetated, providing safe waterway and former active erosion hehand [sic] structure is almost 100% stabilized.” Both men in this picture are UNIDENTIFED.

Photograph of old vegetation at the Red Plains Experiment Station. The old vegetation, after moving mature grass plants, provided a mulch which reduces erosion. This mulch creates a silt deposit and attention is called to the young grss seedlings which are emerging. This is important on badly eroded abandoned areas which are being revegetated. OK-8349.

Photograph of a retired field with severe washing causing a small gully to form. A dirt road is on the left of the photo and several buildings are in the background. The back of the photograph proclaims, "Gully control with small earthen dams. Small gullied area retired from cultivation because of severe washing. Small dams have Bermuda roots mixed in to promote vegetative cover. Vernon F. S. L."

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.

Terraces and grassed channels have been constructed and contour cultivation is now practiced. A volunteer ceop of wheat serves as winter cover and supplemental pasture for livestock.

Photograph of erosion control project. Lateral roads were formerly unassessable due to huge gully across roadbed. Area has been resectioned and sloped, a drop inlet and two culverts constructed by WPA. Safer roadways and safer waterways result.

Photograph of roadside erosion control project. Fill has been made in road and drop inlet and old bridge and severe gully formerly filled the center area of this intersection. Lateral roadways were impassable before erosion control work was started.

Photograph of masonary arch drop, gully control terrace outlet channel. Masonry structure was built latter part of 1937 in natural wash, badly gullied to accelerate silting for erosion stabilization. Outlet channel on right is now well vegetated, providing safe watersay and former active erosion behind structure is almost 100%.

Photograph of "Class II land. Level ridge-type terraces constructed on gently sloping heavy textured soils to conserve moisture and soil." A barn or house is in the distant background.
