Photograph of a gully caused by 19 inches of rainfall occuring within a 7 hour period on June 22, 1948. This gully, 25 feet deep and 40 feet wide, is several blocks long and lies in the middle of what was a travelled street before the rain started. Less than 2 [unclear] of land drain into the gully above its head. OK-9675.

Photograph of a close-up showing how exactly soil blows as William Trarel sifts it through his fingers. This is a lower part of a 65-acre field of cotton, grain sorghum and sudan grass that washed out in 19 inches of rain on June 22, 1948. Silt deposited in the lower part of the field has created a blow problem. OK-9657.

Photograph of a view east across top of detention reservoir No. 1 on Cloud Creek. The 3 trucks at the pool of water are sprinkler equipped. Owned by the Oklahoma Department of Agriculture, the trucks were used to keep down dust on sandy roads during the dedication ceremonies on the upstream flood control structures. OK-9619.

Photograph of Terry Mccarty, who points to the top of an old fence. He built new fence when silt piled up on 1/2 acre of his bottomland. Silt washed down from road and pasture of inferior vegetation that did not adequately protect soil in heavy downpour on June 22, 1948., a natural drain in the middle of the pasture becoming a gully. Silt averaged 3 feet [unclear] or 6,000 tons over 1/2 an acre. OK-9654.
