Photograph of a Finn mulching machine demonstration. A Finn Klodbuster consisting of a series of chains with picks, which revolve around on swivels as it is being pulled. A variable weight slope wheel keeps the chain at an approximate right angle to the towing vehicle on slopes 3:1 and steeper. Here it is being used to spike down a one ton application of broom corn stalk mulch. The unit should be long enough to cover the area with one through [sic] to avoid leaving a deep track on the dam made by the wheel at the end of the chain. OK-214-12.

Photograph of a Finn mulching machine demonstration. A Finn mulch spreader applying mulch at the rate of 1-ton per acre, following seedbed preparation. Feed chute is adjustable to load heights for bales materials. Side extensions are furnished for loose material. The mulch is spread by a 24 inch centrifugal fan, powered by a 36-HP motor at 2200 rpm. Discharge head has a 360 degree horizontal swing and a 75 degree vertical swing. The operator is Fred Whittington, range Conservationist, Soil Conservation Service [SCS], Elk City, Oklahoma. OK-215-2.

Photograph of an aerial shot of Cloud Creek Watershed Detention Reservoir #1 and the surrounding area. The back of the photograph proclaims, "Cloud Creek Watershed. Ok-SCD-WA-#5. Detention Reservoir #1. The drainage area is 1300 acres of this 850 acre cultivated & 450 pasture. Medium textured, permeable soil. Drainage area in good condition. 4 drop inlets are above this structure which will hold the silt from above it. Permanent storage – 30 surface acres; 195 ac. ft. & 1.8 ac. Inches. Flood pool 56 surface acres; 380 ac. ft. & 3.5 ac. inches. Peak flow uncontrolled (25 year frequency) approximately 3000 cfs. Release rate from reservoir at present time approximately 400 cfs. Drop inlet is 3 ft. 6 inch concrete box with concrete stilling basin. It is planned to put cap on drop inlet to out discharge to 60 cps. Benefit cost ratio 5.3/11. See Okla-8601-A, B, & C. and Okla-9537."

Photograph of an aerial shot of Drop Inlet #5, Cloud Creek Detention Reservoir #1, and the surrounding area. The back of the photograph proclaims, "Cloud Creek. Ok-SCD-4. Wa. No. 5. Drop inlet. Drainage area 272 acres. Approximately 4-inch storage in permanent pool & approximately 5-inch storage in flood pool. (Note white marker at arrow – point shows the flood pool elevation). The soil unit is shallow, medium textured, permeable soil. 130 acres cultivation & remainder pasture land. Drainage area has most of the mechanical conservation practices applied & is in good condition. This drop inlet is above Detention Reservoir #1. It was installed to control overfall above it cutting back into cropland. One overfall is on right hand side of picture."

Photograph of an aerial shot upstream from a flood seen in Olka-10-013, Okla-10-015, Okla-10-016, Okla-10-018, and Okla-10-021, which was at its highest point when this photo was taken. The back of the photograph proclaims, "The flood shown in Olka-10-013, Okla-10-015, Okla-10-016, Okla-10-018, and Okla-10-021 on the Washita River was developed from rains below this point on the Washita. This photo was taken of the river at the highest stage during the flood lower down at Mountain View, Carneige [sic], Fort Cobb, and Anadarko."

Photograph of a drop inlet on Cloud Creek watershed operating after a 4. 6 inch rain in 4 hours. This drop inlet is above Detention Reservoir No. 1. Very little of the one inch flood storage was used. A 48 inch pipe is through the dam and the 280 acre drainage area had good land treatment on it.

Photograph of detention reservoir # 2, Cloud Creek, one hour after a 4.6 inch rain fell in 4 hours. No water was discharged past the dam. There was approximately 1.2 inches of runoff. The earth embankment is 32,315 cubic yards. The drainage area is 600 acres. The permanent pool is 7.5 acres. 70 acre-feet storage and 1.4 inches [depth of water coverage?]. The flood pool is 18.6 surface acres. 113 acre feet storage 2.3 inches [depth of water coverage?]. Cost is $16,661.00. Benefit / cost ratio is 5.3 / 1. See OK-9541 and OK 9542. OK-10, 011.

Photograph of Bob Deevers, opr. , inspecting a waterway that was constructed and sodded to Bermuda grass in 1960. Terraces were constructed after wheat harvest in 1960 to outlet into this waterway.

Photograph of contour blanklisted furrows that not only protect this field but also collects soil blown from the unprotected field in the background. The angle at which the center figure is leaning into the wind indicates its velocity. OK-5466.

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 an excellent crop of Kafir corn on contour in former 5 acre area of severely gullied natural draw where owner had never made a crop. An erosion control dam was constructed across the deaw in 1937 and in two years the land was producing crops. To date the draw has silted in approximately 5 feet says Mr. Lucas.

Photograph of two acre Bermuda grass pasture strip developed from a badly gullied draw. The draw was sloped and sodded in 1938 and now provides grazing at the rate of 1 unit per acre and serves as an outlet channel for 70 acres of terraced and cultivated land. Mr. Fred Bunch states that this pasture strip furnishes better grazing than any of his 28 acres of native pasture on this 160 acre farm. He also states that his soil conservation practices have increased by $1,000 the value of this farm. Terraces were built with the assistance of the old Sentinel Civilian Conservation Corps [CCC] Camp. OK-8467.

Photograph of terrace outlet channel under construction. Channel will be widened, shaped and sodded. Vegetation will be allowed to become well-established before terrace water is emptied into it. Terraces will be constructed in the field and will empty into channel from both sides. Mr. Ray Murrell, Work Unit Conservationist, and Mr. Paul Hertzler, farm owner, examine a conservation survey map on which the location of the channel and terraces are indicated. OK-8916.
