Photograph of a view of water impounding Plot 2 as seen from the top of the lower dyke. This plot was flooded two times previously for 10 days from 3/21/61 to 3/31/61 and again from 5/3-13/61. No damages were noted from the first flooding; however, considerable damages were noted on certain grasses during the second flooding. Numerous grasses did not survive and growth was suppressed on others. Water depth varied from in excess of 6.0' in foreground to zero in the background. 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 1 as seen from the top of the lower dyke. This plot has been flooded two times previously for 5 days from 3/21-26/61 and again on 5/4-9/61. Only slight damages were noted as a result of these floodings. Major effect noted was the suppression of growth with an increase in depth of flooding. Water depth varied from in excess of 6.0" in foregroun, to zero in background. This study is in response to SCS research needs. Work is under the supervision of Edd D. Rhoades, Agricultural Engineer, ARS-SWC.
