'l'he Sevier ili ver <br />System rises on the rim ,of the Great Basin in Southern Utah. <br />It flows for a distanco of about two hundred miles north and <br />then s'l'ings to the Southwest and discharges into ~evier Lake. <br />On the ~evier rliver 3ystem there are in the neighborhood of <br />forty independent canals taking water.
