Abstract : Dredged material containment areas (DMCA) differ physically, biologically, and chemically. Structural variability includes size, configuration, foundation conditions, water retention properties, and the presence of interior cells. Levees differ in height, width, continuity, and adaptability to aquaculture. Locations may be remote or have ready access to roads and commercial power sources. Water control structures vary in location, state of repair, and usefulness to the prospective culturist. Infrequently used DMCA may be heavily overgrown, while active DMCA, containing sand, silt, or clay, often have irregular bottom topography and potentially unstable interior soils. Most DMCA are biologically productive during inactive periods, but potential contaminants within or scheduled for disposal in DMCA should be assessed. The length of time an area is active and the frequency of disposal, important impacts in DMCA aquaculture activities, should be incorporated into all planning. Cooperation from the local Corps District is anticipated. (Author)
