Central Sierra Trout Unlimited's mission is to conserve, protect, and restore the coldwater fisheries and their watersheds in Calaveras, Fresno, Kern, Kings, Madera, Mariposa, Stanislaus, and Tuolumne Counties. Through our efforts in conservation, policy, and education we strive to improve our local watersheds encompassing the Mokelumne, Stanislaus, Tuolumne, Merced, San Joaquin, Kings, and Kern river drainages.
