During springtime, stocked trout in lakes and reservoirs can be found fairly shallow, feeding in the upper 10 to 15 feet of the water column.
Trout move deeper in the water column to seek out cool water as summer sets in and surface waters warm.
Trout, browns, brookies, and rainbows are coldwater species, so they like cold water and remain active under ice cover.
As lakes warm in the spring, largemouth bass move into shallow cover in coves, canals, and harbors. They seek warming water offered by these spots that also provide plentiful baitfish.
Docks and boat houses are important cover for bass, particularly when shoreline development has depleted natural cover. High-percentage spots depend on water depth and cover options.
After the spawn, big bass quickly move to offshore structure, where they hold along humps, ledges, or deep underwater points. They're ready to feed, so whet their appetite with a big deep-diving crankbait.
When water temperatures tumble below the low-40F range, bass often move from mid-depth flats to more vertical structures. Fast-breaking edges allow bass to change depth easily, without traveling long distances.
One of the hottest tactics on the pro bass trail is working deep structure with jigworms, sometimes called shaky-head worming.
Carolina-rigging has been the favored fall tactic of pro anglers for probing reservoir structure. Some call the technique power fishing with finesse because you use stout tackle, but the action of the lure is subtle and tempting to fish.
