Photograph of soil from farms in Mississippi watershed spurts from a pipe after being dredged from the harbor. Soil is spewed into stream channel where current is strong enough to carry it further downstream. LA-62, 278.

Photograph of soil from Mississippi watershed farms spewing from the end of a pipe line into a stream channel where the current is strong enough to carry it further downstream. Suction dredge is clearing channel to permit ships to dock. LA-62, 277.

Photograph of a suction dredge in the background that is clearing channel to permit ships to dock. The sand spewing out the end of the pipeline represents soil from the Mississippi watershed farms. At this spot dredging will go on for 12 days from a 100-foot line to deep water. Dredging 500 to 550 cubic yards an hour continuously. 500 cubic yards is equal to a farm of 178.5 acres with topsoil 6 inches deep for the 12-day dredging period. Sediment here is 9 feet deep. The water must be kept at a 35-feet mean for low gulf. This job is being done by a private contractor under the supervision of U.S. Corps of Engineers. LA-62, 279.
