Abstract:

This statement addresses the Operation and Maintenance of the Crooked River portion of the Inland Route, Michigan, including dredging, dredge material disposal, and the continued operation and maintenance of the Crooker River lock and weir at Alanson, Michigan. Since an upland disposal site would be used, a transfer facility would also be required. Dredged material removed from the Crooked River would be transferred to trucks at the foot of Snider Road at the Crooked River, and hauled to the disposal site, located approximately one 1 mile north on Snider Road. The estimated annual shoaling rate in Crooked River is 1,000 cubic yards, and the river will require about 9,500 cubic yards of backlog dredging. Thus, the total capacity of the site for 10 years is 19,500 cubic yards. Maintenance dredging is necessary to restore the waterways ability to accommodate recreational craft navigation. The proposed Federal action also includes operation and structural maintenance of the lock and weir on the Crooked River at Alanson. Structural maintenance and operations are required to insure continuance of vessel passage along the Inland Route. Water level regulation of the upstream rivers and lakes is a function of the lock facilities. Additionally included in the action is the proposed construction of public use facilities at the lock. The plan provides for the construction of a parking lot, restroom facilities, storage building, observation platform and docking area, and landscaping. Author
