Covering water is the key to steelhead fishing. Sure you can plant yourself in a meathole and eventually get one but you may be competing with quite a few others doing the same thing. Do the math. If you are fishing a spot that holds 10 fish but has 20 guys fishing it, thats 1 to 2. If you move around and cover more water and find a run that has only 1 or 2 but you are the only one fishing it, your odds are much better. That said, don't be afraid to go back to a spot that you fished earlier as the fish do move around a bit and that spot that was previously empty may hold a fish in it. Sometimes all it takes is for the sun to peek through the clouds and wham, the bites on again. A change in lighting will get the fish to move to a different part of the run. When they do that, they are much more apt to "bite" again.
