Kaskaskia River Navigation Project Illinois PDF Download

The proposed Kaskaskia River navigation project will provide a 50-mile-long, 9-ft-deep by 200-ft-wide channel from the mouth of the river to Fayetteville, Ill., by means of channel enlargement and realignment; alterations to bridges to obtain proper clearance; and construction of a gated dam surmounted by two 60- by 30-ft tainter gates, and an 84- by 600-ft navigation lock. A 1:120-scale, fixed-bed model, reproducing 2.0 miles of the Kaskaskia River and 1.8 miles of the Mississippi River, was used to: demonstrate and study flow conditions in lock approaches and in critical reaches; determine adequacy of proposed design for the spillway, stilling basin, and exit channel; determine optimum arrangement of the guide or guard walls; determine areas requiring special protection and navigation conditions in lock approaches and in critical reaches; and develop modifications required to produce satisfactory flow and navigation conditions.
