Photograph of Ionine Creek, an aerial view of a critical silt source area. This huge gully has been treated vegetative, and a structure is to be built on the lower end. Fields were planted to native grasses and tree plantings made in 1957.

Photograph of watershed site 22, Rush Creek. Follow-up of OK-1240-6; just after completion of structure. Lake is now full. Excellent stand of bermuda grass in spillway area and on dam. Also used for stockwater.

Photograph of dam, fence and spillway and gate looking East. This picture made before being sprigged with bermuda grass and before structure has filled with water. Present water is in borrow pit.

Photograph of follow-up of Ok-1266-10 and Ok 1261-2, 3, 5, & 6. Pipe in place and road completed across spillway. Entire road across dam and spillway was graveled. Excellent cooperation between County Commissioner, Grady County District, and SCS. Looking East. Also School bus route.

Photograph of water impounding Plot 5, one of six being used to study water inumdation tolerance of selected species of grasses associated with flooded areas above floodwater retarding structures. Viewed from top of embankment at lower end of plot. Edd D. Rhoades shown standing at the 5 foot depth location. This plot has been flooded two times; 4/30/61 to 5/10/61 (10 days) and 6/12/61 to 6/22/61 (10 days). Slight damage was noted after the first flooding and considerable damage was noted after the second flooding. This study is in response to SCS research needs. Work is under the supervision of Edd D. Rhoades, Agricultural Engineer, ARS-SCS.

Photograph of a close-up of KSU lowland switchgrass (in front of sign) in impound basin number 4 at a depth of 5.0 feet following two floodings for 10 days during early spring (3/22-4/1/62) and mid-spring (5/3/62). Ther was a slight suppression of growth, however, there was no killing of any part of the grass at this depth. For view of this grass when flooded at the same duratio at a depth of 1.0 foot, see OK-1760-6 dated 6/8/62. This research is under the supervision of Edd D. Rhoades, Agricultural Engineer, ARS-SWC.

Photograph of buffalo grass (in front of sign) in impoundment basin number 6 at a depth of 5.0 feet following two floodings for 20 days during early spring (3/21-4/10/62 and mid-spring (5/2-22/62). Severe suppression of growth with approximately 75 percent of top grwoth killed during mid-spring flooding. All grass at this depth had recovered well at date o photograph. For view of this grass when flooded at same time, except for a depth of 1.0 foot, see Ok-1760-4, dated 6/8/62. This research is under the supervision of Edd D. Rhoades, Agricultural Engineer, ARS-SWC.

Photograph of Mr. E.H. Rhoades, left, Agricultural Engineer, ARS-SCS, discusses with SCS Agronomist M.D. Gamble, the establishment of 24 selected species of grasses and legumes related to watershed treatment. Reddish Prairie, virgin rangeland, Noble loam, slope 7%, erosion 1, Class IV. Work is under the supervison of Mr. Rhoades. Work in response to SCS research needs.

Photograph of a water impound lot, looking north, constructed by ARS-SCS to study inundation tolerance of selected species of plants associated with watershed treatment (floodwater retarding structures). Water will be 5 feet deep at lower end of plot. Six plots are planned for the study. Reddish Prairie, virgin rangeland, Noble loam, slope 7%, erison 1, Class IV. Work is under the supervision of Edd. D. Rhoades, Agricultural Engineer, ARS. Project is in response to SCS research needs.

Photograph of prarrie cordgrass (first grass in front of sign) vine Mesquite (second grass in front of sign) and alkali sacaton (foreground) in impoundment basin number 4 at a depth of 1.0 foot following two floodings of 10 days during early spring (3/22-4/1/62) and mid-spring (5/3-13/62). There was no evidence of damage to any of the grasses, except a very slight suppression of growth. For a view of this grass when flooded at same time, except at a depth of 5.0 feet, see Ok-1760-7, dated 6/8/62. This research is under the supervision of Edd D. Rhoads, Agricultural Engineer, ARS-SWC.

Photograph of prarrie cordgrass (in front of sign) in impoundment basin number 6 at a depth of 5.0 feet following two floodings of 20 days during early spring (3/21-4/10/62) and mid-spring 5/2-22/62). Note the severe suppression of growth. For a view of this grass when flooded at same time, except at a depth of 1.0 foot, see Ok-1760-2, dated 6/6/62. Grass in foregound is vine mesquite, which was only slightly damaged from the foregoing inumdation. This research is under the supervision of Edd D. Rhoads, Agricultural Engineer, ARS-SWC.

Photograph of water impounding plot (one of six) constructed by ARS-SWC to study inundation tolerance fo 24 selected species of plants associated with water shed treatment (floodwater retarding structures). Water will be 5 feet deep at lower end of plot with controlled periods of inundation. Common Switchgrass, lowland switchgrass and Midland Bermudagrass. Work is under supervision of E.D. Rhoades, Agricutural Engineer, ARS-SWC. Project in response to SCS research needs.
