From the mid 1960's until 1991, dredging and disposal occurred in the northern Chesapeake Bay without guidelines to maximize the capacity and to minimize the spread of the deposits beyond the disposal sites, particularly toward the navigation channel. Planning for future dredging projects is dependant upon the remaining site capacity and the behavior of the disposed sediment. Recent studies have shown that the fate of the deposited sediments is determined primarily by the water depth and bathymetry in the vicinity of the disposal site, and the method of dredging and disposal utilized. Currently used open-water disposal sites in the northern Chesapeake Bay are reaching their maximum capacity. This makes the application of the information from these studies critical, both for the optimal use of current sites and for the evaluation of new sites. Management scenarios utilizing these studies are applied to a disposal site in the northern Chesapeake Bay.
