Game fish
According to the California Department of Fish and Game, "many of the waters in the headwaters of the South Fork Kings River and several tributary streams and lakes were also planted with California golden trout from GTC (Golden Trout Creek) between 1909 and 1914." the California Department of Fish and Game fish data base from their surveys indicate that only rainbow trout, brown trout and Sacramento sucker are found in the South Fork Kings River. The Park Service used to stock rainbow trout in the river, but terminated the practice in the 1980s in favor of letting the fishery return to more natural conditions. However, the South Fork is still considered excellent water for fly fishing in Kings Canyon.
