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.

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.

Work is being conducted by Edd D. Rhoades, Agricultural Engineer, ARS, in response to SCS research needs.

Photograph of west side of water impoundment Plot No. 2 previously flooded three times for 10 days each as follows: (1) 3/21/61 to 3/31/61; (2) 5/3/61 to 5/13/61; (3) 6/13/61 to 6/23/61. Considerable damage to grasses resulted from these inundation periods. This study is in response to SCS research needs. Work is under the supervision of Edd D. Rhoades, Agricultural Engineer, ARS-SWC.
