On a bright afternoon near a narrow cove under flat light, the fish mix is not confirmed, so check fresh local information before choosing a target or keeping a catch.
On an overcast morning near the downwind side in clear water, begin with one slow bottom presentation and one moving bait, then let bites show whether fish are holding close to cover or roaming open water.
On a calm morning near a windblown shore where two features meet, use wind as a clue; a light push can carry food toward a bank, but hard wind may muddy it, so look for a clean edge near a point or protected pocket.
While using a quick comparison of two banks near a small drop after a cold night, 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.
On a low-light period near an open-water edge near visible bait, a medium spinning rod, 8-pound line, a small box of jigs, a few crankbaits, and a simple bottom rig cover most situations; change depth or speed before changing every piece of tackle.
On a steady fall day near a narrow cove before changing areas, record the wind, water color, depth of the best pass, 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.
