Fish listed for Thunder Lake include Rainbow Trout.
Around the narrow end of a quiet pocket, cast a small spoon, inline spinner, light jig, or fly through cool water for rainbow trout.
Along the current seam of a broad flat, do not let the deepest number control the whole day; nearby cover, firm bottom, and food usually matter more than the deepest hole by itself.
Along the outside edge of a shaded bank, early in the year, protected water and the first warm afternoon can be the best clues; as the water heats up, check deeper edges without assuming every fish is on the bottom; cooling fall water often makes points and firm banks useful again.
Near the narrow end of a firm-bottom flat, a light spinning rod, thin line, a few small spoons, inline spinners, and jigs cover the listed trout; carry one slightly heavier setup when other fish or windy water call for more control.
Along the calm side of the first drop, record the wind, water color, depth where the bait worked, and cover after a bite; those four notes are more useful on the next trip than a long list of spots that did not produce.
