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 Edd "D. Rhoades, Agricultural Engineer, ARS-SWD, checking water temperature in one of six water impounding plots being used to study the inumdtion tholerance of selected species of grasses associated with flooded aeas above floodwater retarding structures. High and low water temperaturews are checked daily. 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 of water impounding Plot 6, one of six being used to study the inundation tolerance of selected species of grasses associated with flooded areas above floodwater retarding structures. This plot previously flooded 4/30/61 to 5/5/61 (5 days). Very little damage to any grasses was noted as a result of this flooding. 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 close-up view of the center of water impounding Plot 3 as seen from lower side. This plot has been flooded two times previously for 20 days from 3/22/61 to 4/11/61 and again from 5/2/61 to 5/22/61. None to slight damages were noted from first flooding; however, severe damages and loss of grass resulted from the second flooding. 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 of water impounding plot 3 as seen from fenceline at upper end. Water depth vaiies from zero to 6.0'. Previous flooding 3/22/61 to 4/11/61 for 20 days. This flooding started 5/2/61, to be drained 5/22/61. Grass in foregound is being used as a check plot. This study is in response to SCS research needs. Work is under the supervision of Edd D. Rhoades, Agricultural Engineer, ARS-SWC.

Photograph of the view of water impounding Plot 3 as seen from top of lower dyke. Water depth varies from 6.0' in the foreground to zero in the background. Grasses shown above the water line in the backgound are being used as a check plot. This study is in response to SCS research needs. Work is under the supervision of Edd D. Rhoades, Agricultural Engineer, ARS-SWC.
