Photograph of a panoramic view of six water impounding plots used to study inundation tolerance of selected species of grasses associated with flooded areas above floodwater retarding structures. Plot 6, to the right, has just been drained. This view is from hillside above southeast corner of plots. This study is in response to SCS research needs. Work is under the supervision of Edd D. Rhoades, Agricultural Engineer, ARS-SWC.

Photograph of a panoramic view of six water impounding llots being used to study inundation tolerance for selected species of grasses associated with flooded areas above floodwater retarding structures, as seen from southwest fence corner. Plot 1 is shown in the foreground. This study is in response to SCS research needs. Work is under the supervision of Edd D. Rhoades, Agricultural Engineer, ARS-SWC.

Photograph of a view across upper end of Plot 3 while flooded. This shows plants protruding from water simulating actual condition in detention reservoirs. This plot was previously flooded from 3/22/61 to 4/11/61 and current flooding commenced 5/2/16 and is scheduled to continue until 5/22/61. This study is in response to SCS research needs. Work is under the supervision of Edd D. Rhoades, Agricultural Engineer, ARS-SWC.

Photograph of Perry Howell and son Dwight standing in a field of contour-drilled grain on an Oklahoma School land farm which is under a 5-year cooperative agreement with the Soil Conservation Service. Howell and his son have instituted a complete program of erosion control on the farm where Howell has lived as a tenant for more than 30 years. OK-6470.

Howell and his son have instituted a complete program of erosion control on the farm where Howell has lived as a tenant for more than 30 years. OK-6470.

Photograph of the Austrian winter peas crop on the School Land Farm operated by Perry Howell near Blackwell, Oklahoma. The use of winter cover crops is helping Howell to put into effect a complete program of erosion control on the farm he has leased for more than three decades. OK-6469.

Photograph of uniform grazing. Close-up of an inlet, overflow and storage pond below tank. Velton Stanford, son and partner at the inlet. Neal Stidham, Soil Conservation Service [SCS], present at the overflow with D. L. Stanford, the owner-operator. Usually operations feeding out 600 to 800 steers on 6500 acres of bluestem. Steer gains in normal years average 350 pounds each—full grain feeding on limestone prairie site in Good Condition class. OK-262-1.

Photograph of uniform grazing. In an area of underused range grasses, Mr. D.L. Stanford drills a wall, installs a freeze-proof pump, a pipe to a water tank, with overflow pipe taking surplus water to an earthen tank for emergency resevoir, thus aiding uniform use according to Conservation Plan. OK-261-12.

Photograph of uniform grazing. Windmill and tank in the windmill-four-wire pasture. The overflow goes to the middle four-wire tank thence to the reserve earthen tank. Well drilled and water facilities developed to secure more even use in range grasses. District Conservation Plan also includes additional pond construction. OK-262-4.

Photograph of a tentative range site is Rocky prairie. Excellent condition Dolomite limestone rock with pockets of deep fertile soil between outcrops. Dpminant vegetation is big and little bluestem and Indiangrass.
