This is a very interesting movie about the early days of flyfishing for steelhead and salmon in Northern California. If we think the waters are crowded now, they were really crowded in the fifties on rivers like the Eel and Smith.
This movie is 1hour 26 minutes long, but if you've never seen it, it's worth the effort to see what the "good old days" were like, and what impacted/caused the change in the fisheries. The only thing I found troubling was the lack of enviro-sense the early anglers possessed. I guess if you assume the resource will be there forever you aren't as concerned about the resource. I also found it interesting how when an article went into a magazine or a book was written about the fabulous fishing, the regulars were shocked when the hoards descended upon the rivers written about. Some things never change.
The movie is RIVERS OF THE LOST COAST
