I would blame the CA DF&G for developing such a large hatchery run up there of Kings, Silvers and Steelhead. Ha ha...only kidden'
In the 1980s after the big drought of the late '70s there was no one on the Trinity River or Klamath because there were very few fish.
If we had a budget to pump up the lower American River's winter Steelhead run it would be crowded too.
