Photograph of a water diversion completed in Oct. 1959. Farmer is preparing seed bed for rye grass now. He plans to sod with bermuda grass in spring of 1960. This diversion was constructed to take care of a 200 acre drainage.

Photograph of Bermuda sod on the front slope of a dam—sodded and fertilized in 1949—occasional light grazing. Sod shows some evidence of breaking up and probably should be fertilized in the near future. Has provided excellent protection to the structure. OK-3134-4

Photograph of view across dam on detention reservoir, Site No. 2. Woodland Watershed of the Washita River. Drainage area 620 acres; 41/2 feet in permanent pool, 248 acre foot of flood storage; can hold back 4. 8 inches of rainfall.

Photograph of deep gully caused by improper terrace outlets. It is to be shaped and sodded to bermudagrass and terrace water eliminated. Picture looking east toward the head of the gully.

Photograph of oak brush as sprayed in 1957 and 1958 with 2-4-5T herbicide. Grazing was deferred following spraying to allow the grass to make seed and improve the stand. OK-726-4.

Photograph of a close-up shot of native grass in area sprayed for oak brush control. The back of the photograph proclaims, "Native grass in area sprayed for oak brush control, in 1957 and again in 1958. Large plants of little bluestem, Indiangrass, switchgrass, and big bluestem made seed in fall of 1957. Small grass plants are seedlings of above grasses. Deferred grazing has made it possible for rapid range improvement following spray jobs."

Photograph of overflow damage above Site 4, Chigley Sandy Creek Watershed. This bottom land is not protected by floodwater retarding structures. The crop of small grain was up to a good stand and will have to be replanted. Overflow was caused by an unofficial 7.7 inch overnight rain.

Photograph of the front slope of a floodwater retarding structure showing wave action damage. E. L. Castle, WUC, Lindsay. Spillway cut in background shows erosion from hard rains in Oct. & Nov. Bermudagrass planted 2-28-59. Irrigated immediately after planting. Moisture favorable during most of growing season. Subjected to grazing since June. Weeds mowed 8-20-59.

Photograph of harvesting Bermuda grass roots. Harvesting Bermuda grass roots for sodding flood retardation structure on the Chigley-Sandy Creek Watershed. Windrow roots immediately with a side delivery rake or other suitable farm equipment. Roots should be loaded within 30 minutes after freeing from the soil to prevent excessive exposure to the sun and wind. OK-227-10.

Roots should be loaded within 30 minutes after freeing from the soil, to prevent excessive exposure to the sun and wind.

Photograph of Harvesting bermudagrass roots for sodding flood retardation structure on Chigley-Sandy Creek watershed. Area selected for root harvest is free from weeds, escessive top-growth, debris and rocks that would interfere with sodding operations. Tight soil is not too good for harvesting roots, as more work is needed to remove roots from the soil. Work the field in narrow strips. First time over the area, chisels should not be set too deep. Each trip go deeper until roots come to surface freely. Avoid harvesting weak rhizomes from old sod bound or overgrazed areas.

Photograph of an automatic Bermudagrass sprigging machine (one row 3 point hookup) planting Bermudagrass on outside spillway cut. Sodding equipmant must be anchored to the truck or tractor on top cut or dam. One of the problems connected with this operation is getting grass planted at sufficent depth to prevent loss of roots from excessive drying. Anchor cable length is adjusted for each trip. Work being done under contract.

Photograph of water being applied after sodding. Furrows were left to hold water. Water is being supplied by an irrigation pump and a 2-inch fire hose. A half inch of water applied following sodding assures a better stand, especially during periods of high wind. A sprinkler irrigation system can also be used effectively.

Photograph of an aerial shot of Site #7, Wildhorse Creek Detention Reservoir and the surrounding area. This area was formerly known as Site 6, Woodland Watershed. The back of the photograph proclaims, “Detention Reservoir- Site #6, Woodland Watershed. Permanent Pool – 0.78” runoff. Flood pool – 4.75” runoff. Total – 5.53” runoff. Drainage area – 1350 acres. The permanent pool surface area is 13.2 acres. It will cover 37.6 acres when it reaches the emergency spillway at left.”

The back of the photograph proclaims, “Bridge (on river) on reenforced [sic] concrete piles was overtopped by flood water. Several of the piling failed by shifting downstream.”
