Maintenance of the Breton Sound reach of the Mississippi River-Gulf Outlet has proven to be a most difficult task to meet the demands of shipping. The second maintenance dredging contract, extending from mile 23.3 to mile 2.0, was initiated and completed 9 December 1964 and 23 January 1966, respectively. The quantity of material to be dredged was revised by addendum during advertisement from 11,450,000 to 14,124,000 cubic yards, to reflect approximately 2 months of shoaling. The quantity was further revised to 23,338, 000 cubic yards by modification of the contract to reflect additional shoaling. The extension of the southwest dike from mile 20.2 to mile 14.9 and flanking dike at mile 14.9 will alleviate this maintenance dredging problem.
