Hat Creek is the home of California's first Wild Trout designated water. In the early '80s the river boasted trout counts of 6,800 fish per river mile. That was before a major plug of sediment moved in, choking aquatic vegetation, hindering bug populations, and speeding the flow. The good news, according to CalTrout, is the sediment plug has largely passed the Carbon Stretch and there are signs of rebound in the upper reaches.
