Damaging quantities of natural <br />mineral salts are contributed by some tributaries of the Arkansas <br />and Red Rivers. .These include the Salt Fork, C1marron, and Canadian <br />which drain to the Arka:nsas Ri-ver. Gypsum and salt deposits in the. <br />western part of the Red River Basin contribute mineral polluti91J. .to <br />that river through the Prairie Dog Tovm Fork, Pease River; . andt1i.a <br />North Fork and the Salt Fork. A major part of the sediment load is <br />contributed to the Arkansas River from above the Arkansas-Oklo.holllll. <br />State line. The South Canadian River Basin contributes ti.major' part <br />of this type of pollution, and heavy sediment loads arealilo oarried <br />by the' Red River above Den~son Dam. 1\lajor tributilriesdf,the Arkansas <br />River carrying a heavy oil field brine pollution load include the' <br />Canadian Md Cimarron Rivers. The water quality in the Red River <br />Basin is also seriously .affeoted by oil field brines, and the principal. <br />tributaries contributing this type of pollution inolude Cypress Creek, <br />Sulphur River,.
