Other Gulf-State IVattrteayt Develop:nest.— Red River is 1,275 miles long and from its month in Louisiana to Fulton. Ark., the distance is 482 miles. It is under improvement. From Felton to Shreveport, La., there is a minimum depth of five feet and from Shreveport to its month there is a minimum depth of seven feet from December to June when the water is high and the river within its improved sections may be navigated, but not at other times. At high of water light draft vessels have and may sail ascend as far as Denison, 763 miles above its mouth and 11 miles below the outlet of the Washita. At Denison there is in some months a depth of five feet in the channel. Lanesport, 73 miles above Fulton, formerly was at the bead of navigation, though boats occasionally ascended to the mouth of the Kiantichi. 158 miles above Fulton, Ark. Some clearings of the channel and dredging has been done in the lower 51 miles of the Sulphur River, and dur ing high water in the Red River there is a back water flo• into Sulphur River for 50 miles which render the lower reaches of the latter navigable for light draft steamboats for a dis tance of 17 miles for rather irregular and short periods of time. The channel of the lower part of Cypress Bayou for 66 miles is being dredged and straightened from Red River at Shreveport, La., to Jefferson, Tex. A dam has been con structed without a lock at the foot of Caddo Lake, which is 17 miles across. That dam cre ates a pool extending 43 miles to Jefferson City.
Tex., which insures a navigable waterway four feet deep.
The Vicksburg, Miss., district comprises 16 rivers and harbors, some of which have al ready been described. The Ouachita River, Ar kansas, is being improved by the construction of eight locks and dams and by clearing the channel so as to afford a navigable depth of six and one-half feet of water from the mouth of Black River, Louisiana, to a point 10 miles above Camden, Ark., a distance of 360 miles. The lock chambers are 55 fcct wide and 268 feet long and have lifts of five and one-half to 14g feet. In 1917 the tonnage over that waterway was 178,136 tons. The Tensas, which has its source in Lake Providence and is 235 miles long, joins the_guachita and Little rivers to form the Black River, Louisiana. The Tensas receives, as a tributary, Bayou Mason which is 270 miles long. The channels of both of those streams are being cleared and impressed to make the Tcnsas navi gable from Westwood Place, 81 miles above its mouth, and Bayou Macon from Floyd, 112 miles above its mouth, so as to afford a navigable depth of six feet from January until June. At high stages those channels are 150 feet wide and eight feet deep. The traffic on the two streams in 1917 was 8,344 tons on the sections improved. Bocuf River, Bayou Bartholomew. Saline River, Bayous D'Arbonne and Coney are navigable for light draft vessels in their lower reaches during the months of high water. The Yazoo Riyer, a tributary of the Mississippi, has a channel four feet deep and 500 feet wide its entire length of 178 miles. Loaded boats thereon draw four feet of water. The tonnage of that
river in 1917 was 102,418 tons. The lower 115 miles of the Tallahatchie and the lower 40 miles of the Coldwater rivers have been made navi gable for vessels of three feet draft. Big Sun flower River, a tributary of the Yazoo River, is 216 miles lung and is to have a navigable depth of four and one-half feet and a navigable width of 100 feet for 171 miles above its mouth. In 1917 its tonnage was 61,017 tons. Several other smaller streams in that district have been improved.
The mouth of the Yazoo River is opened up through Lake Centennial to the Mississippi for a distance of nine and three-tenths miles with a bottom width of 98% feet and a depth of six and one-half feet. The canal is navigable all the year. In 1917 its traffic was 61,657 tons.
The lock and dam in the Big Sunflower River at Little Callao Landing. Miss., create a pool of varying depth of one to 22 feet for 61.8 miles up stream and render the river navi gable to Pentecost, Kiss., 124% miles above its mouth. The Little Rock. Ark, district com prises five rivers and the locks and dams on the upper White River. The Arkansas River, 1,460 miles long, a tributary of the Mississippi. is to be improved from its mouth to Neosho (Grand) River, 461 miles. The Grand is gavi gable to Fort Gibson two miles from its mouth. Under ordinary conditions from February to July the Arkansas has a navigable depth of four feet from its mouth to Little Rock, 174 miles, and some years it has a navigable depth of three feet as far as Fort Smith, 369 miles above the mouth. In 1917 steamboats ascended the river to Liftks, 202 miles above its mouth, and gasolene boats ascended to Dardanelle, 261 miles above its mouth. Steamboats with barges of three to four feet draft operated as far as Little Rock for four and one-half months in 1917. The tonnage on that river in 1917 was 38,659 tons. The White River, 690 miles long, a tributary of the Mississippi, is being improved from its mouth to Batesville, a distance of 301 miles, by the construction of works, dredging, etc. A lock and dam has been constructed one mile below Batesville, a second lock and dam seven and eight-tenths miles above Batesville and a third lock and dam nine and seven-tenths miles above Batesville, thereby affording all year slack-water navigation for vessels of three feet draft from the first dam to Guion, a dis tance of 33 miles farther up stream. The locks are 147 feet long, 35 feet wide, and have six feet of water over the mitre sills. At low water in 1917, its controlling channel depth was three and one-half feet from its mouth to Grand Glaize, a distance of 241 miles, and three feet from Grand Glaize to Jacksonport, a distance of 123 miles, and 14 to 16 inches from the latter port to Bates ville. Forsyth, Mo., 505 miles above the mouth of the White River, was at the head of steam boat navigation. For seven and one-half months in 1917 a channel depth of six feet obtained from the mouth to Derail Bluff, a distance of 124 miles. In 1917 the tonnage on the White River was 205,198 tons and that through the three locks was 16,014 tons.
