This investigation was concerned with the development of an adequate navigation channel through the reach of the Arkansas River from the mouth of the Verdigris River downstream to below the new U. S. Highway 62 Bridge, as part of the Arkansas River multipurpose project. A movable-bed model reproducing about 5.7 miles of the Arkansas River in the Webbers Falls Lock and Dam pool, including the lower reaches of the Verdigris and Grand Rivers, to scales of 1:80 vertical and 1:120 horizontal was used for the study. The purpose of the study was to develop a system of training structures that would reduce or eliminate shoaling at the confluence of the Verdigris and Arkansas Rivers, develop a channel through the navigation span of the new U. S. Highway 62 Bridge, and reduce the need for maintenance dredging in the Muskogee Harbor area, without producing currents that would be troublesome for navigation. Results of the investigation indicated that : Satisfactory navigation conditions will be provided with the plan developed, except that some shoaling might occur at the mouth of the Verdigris River during low Arkansas River flows and little or no flow in the Verdigris River. Development of an adequate channel and the degree of shoaling tendencies are affected to a considerable extent by the high elevation of bedrock and gravel bars in the reach. Shoaling in the Muskogee Harbor area can be expected because of its location with respect to the river channel alignment. Shoaling will depend on the amount of sediment moving out of the Arkansas River above the mouth of the Verdigris River during high flows. There is a natural tendency for the channel downstream of the harbor area to cross toward the right bank and shoal along the sailing line approaching the navigable span of the new U. S. Highway 62 Bridge. With dikes placed in the deep channel along the right bank, a channel of adequate depth will be maintained under most conditions.
