| Description: | Technical Report Abstract: Lock and Dam 1 is the first navigation structure for the development of navigation on the Red River Waterway. The structure is located in a cutoff channel in the left overbank about 43.7 realigned channel miles above the Mississippi River. The structure includes one lock located along the left bank with clear chamber dimensions of 84 by 785 ft and a dam, consisting of a spillway with eleven 50-ft-wide gates, that is designed to to provide a normal pool to el 40 upstream to Lock and Dam 2 (mile 74) and to pass a project flood flow of 225,000 cfs. A model reproducing two reaches of the Red River from 1967 river mile 52.0 to 49.8 and from mile 44.0 to 41.5 and the proposed cutoff connecting these two reaches, including Lock and Dam 1, was built for this study. The model was built with provisions to mold the channel bed either in pea rock to an undistorted scale of 1:120 for navigation tests so velocities and current directions could be taken or in crushed coal to a distorted scale of 1:120 horizontally and 1:80 vertically for channel development tests to study bed configuration changes. The model study was conducted to determine navigation conditions and channel developments to be expected from the original design and to develop modifications that might be required to: (a.) improve flow conditions that would be adverse to navigation, and (b.) minimize the dredging required to maintain a channel of satisfactory dimensions along a desired alignment. Results of the investigation revealed the following: (1.) A navigation channel of adequate width and depth could be developed with Lock and Dam 1 located at the proposed site with the modifications developed in Plan B-34. (2.) Little or no maintenance dredging of bed load should be required except after sustained high water occurs with extremely low tailwater conditions. (3.) The channel should remain satisfactory with the proposed mooring facility constructed downstream of the lock as in Plan B-35. (4.) Downbound tows would need to cross to the left side of the channel just upstream of the longitudinal dike, stay along the left side, and maintain speed until they are out of the main channel. (5.) The difference in water-surface elevation across the dam with open river conditions was between 0.1 ft and 0.3 ft for the flows tested. |
