The purpose wa s to de t e r mi ne suitability of wa ter in the Ar m fo r mu nici pa l suppl y . Water quality was de t e rmi ned a t various l ocations a nd depths in Bi g Mineral Arm and was also determined at three verticals in the main body (Red River) of Lake Texoma for comparison with the quality of Big Mineral Arm (Fig­ ure 2). Sampling s i t e s on 16 of the largest tributaries t o Bi g Mineral Ar m were visited on January 18-19, 1966 ( a period of l ow-flow o f the tributaries) , and samples were collected a t 10 s i tes where there was flow. Heav y r ains in the second week o f Fe bruary ca used substantial runoff in the dra i nage a r ea of Big Mi ne r a l Arm. Samples from the 16 inflow sites we r e col lected on February 10-11, 1966, to compare t he chemical qua l i ty of t he wa t er du r i ng high r u noff wi t h that of l ow flow . The quality-of-water survey was do ne und er a co operative agr eement wi t h the city of Sherman and the Texas Water Development Board . Field a nd laboratory work required to sample and a na l yze the inflows into Bi g Mineral Arm during February were done as a part of chemical-quality r econnaissance of the Red River basin, which i s a coo perative pro ject o f the Texas Water Development Board and the U.S. Geological Survey . QUALITY OF WATER OF BIG MINERAL ARM On J anuary 20, 1966, the water i n Big Mine ra l Arm of Lake Texoma was e ssen­ tially the s ame in che mica l qua l i ty from top to bo t tom (Tables 1 a nd 2) . From the analyses it s eems reasonable t o infer that complet e mixing ma y be the nor ­ mal cond i t i o n during the winter . In winter, the a i r t empera ture i s usua l l y lower than the t emperature o f the wa t e r in the lake, and thus t he t op l a yer o f water is cooled, increa sing its de nsi t y. Whe n the density of t he lake wa t e r near the surface becomes grea t er than the dens ity o f the wat er a t the bottom, the t o p l a yer of water moves towa rd t he bo t tom a nd u l tima te ly t he lake becomes completely mixed .
