In its natural state, it was the third-largest salmon- and steelhead-producing river system in California, with over a million fish spawning annually, after the Sacramento and Klamath rivers. The annual chinook salmon run was estimated at 100,000–800,000, coho at 50,000–100,000, and steelhead may have numbered as high as 100,000–150,000. [16]

The act's results vary for different regions and different fish stocks. It did not prevent the overfishing of many species throughout its first 20 years of existence.
