2. The"eye of the pool," or the big slack-water eddy that's often found to the side(s) of the heavy current, where it drops into the head or beginning of the pool.

3. Shade cast by riverside foliage or hills. Can be particularly important in the heat of the midsummer.

4. In front of, alongside of, and behind boulders in swift midstream runs. Especially important in hot weather and low flows.

5. Trout will move into very shallow edge waters to feed on insects that drift a long time on the currents, including mayfly spinners, some duns, midges, and small terrestrials.

6. Upstream and downstream of any bank obstructions such as logs, rocks, and clumps of eroded turf. Many hungry trout prefer the upstream feeding location, where they see the food coming sooner.

8. In pocket water, where rocks make numerous holding eddies and ripple the surface, which camouflages trout.

9. In converging currents at ends of islands and gravel bars.

10. Free roaming in shallow tailouts and upstream of isolated rocks.

11. In depressions in the steambed, the result of shifting gravel, erosion, and ice-gouging in early spring (when the ice blows out).

12. Along grass banks of any depth. It only takes three to four inches of water to cover a trout's back. Here both terrestrials and aquatic insects are found.
