Rafters, anglers and swimmers beware: the Pit River, which flows from Eastern Shasta County to Lake Shasta, is raging this year. The excessive rains and the continually melting record snowpack have swelled the river and it tributaries, including Fall River and Hat Creek. PG&E, which operates power plants on the Pit River, says flows are around 2,000 to 3,500 cubic feet per second, far above the seasonal norm of 350 to 500 CFS. Flows could get even higher when the snowpack experiences warm rainfall or a multi-day heatwave.
