How to Read the Water
Along the windward edge of a weed bed, start where two things meet: weeds and open water, rock and mud, a point and a drop, or clear water and dirty water; fish that edge at more than one depth before leaving it.
Season by Season
Near the lower edge of a patch of green weeds, spring runoff can add color and pull fish toward fresh water; green weeds and the first drop become stronger summer targets; in fall, follow bait toward points and shallow flats, while winter rewards a slower search.
A Simple Tackle Plan
Beside the soft edge of a broad 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 sunny side of a shallow saddle, record the wind, water color, depth of the first bite, 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.
