The books say that for stillwater spawning, they need a spring flowing through gravel, or very clean sand. I know a California biologist however who says he's convinced they don't need the spring, just gravel as long as it's in a low sediment environment. claims he's seen year classes that shouldn't be there in granite catch basin lakes which haven't received plantings in years and that are WAY too high up for illegal plantings. He's not convinced enough to put his name on a paper, or try to get a grant, but as a fisherman, he's convinced. Scary.
