Start with what fish need
Fish gather where they can find food, cover from predators, and comfortable water conditions. If you can spot one or two of those, you usually have a reason to fish there. Instead of asking “where are the fish?” ask “where would a fish want to be right now?”
Seasonal and temperature starting points
Season gives you a rough place to begin. Bass Resource’s guide to patterning bass suggests, as a general starting assumption, that bass are often deeper in winter and summer and shallower in spring and fall. It is a tendency, not a law, and species differ. Water temperature, sunlight and recent weather all shift fish around.
A practical approach is to divide a lake mentally into deep, mid-depth and shallow zones, then use the season to decide which to try first.
Structure and cover
Fish relate to things that change the bottom or break up open water.
- Drop-offs, points and humps where depth changes quickly.
- Weed edges and vegetation that shelter baitfish.
- Wood, brush and rock such as fallen trees, docks, riprap and rock piles.
- Man-made features such as bridges, pilings and culverts.
- Shade from banks, docks and overhanging trees, especially on bright days.
Edges are often better than the middle of a feature: where weeds meet open water, where rock meets mud, or where a shallow flat meets a channel.
Reading current and rivers
In moving water, fish typically avoid the strongest flow and hold close to it, so they can wait for food to drift by. Look for:
- Seams where fast and slow water meet.
- Eddies and slack water behind boulders and bridge piers.
- Deeper pools below riffles.
- Undercut banks and log jams.
In tidal water, flow changes through the day, so the productive spot changes too. See what tides are best to fish.
Signs of life on the surface
- Baitfish flicking or showering at the surface.
- Birds diving or hovering, which can indicate bait below.
- Swirls, rises and wakes.
- Insects hatching, especially for trout.
If you see these, fish nearby. The absence of signs does not mean no fish, since many feed without showing.
Using maps and electronics
Lake contour maps, satellite imagery, and apps can help you eliminate water before you launch. Fishing apps such as Fishbrain collect angler-logged catches and can hint at where people fish, though reports can be outdated or crowded. A depth finder helps you see structure, bait and sometimes fish, but you still need to figure out which are catchable.
Build a pattern by elimination
A method described by tournament bass anglers is to pick one area, such as a cove with varied features, and fish it as if it were a small pond. Work each type of object using a couple of different lures. If you only catch fish on, say, submerged wood in a certain depth, look for similar wood at similar depth elsewhere. That is an individual pattern. If a whole school sits on a patch of weeds, you may stay and work it, which is a concentration pattern.
Keep notes. Depth, structure, cover, time and lure give you a repeatable template, and bait choice follows from what the fish are eating.
Does this creek have fish?
Look for permanent water, pools deep enough to survive dry periods, shade, cover, and some current variety. Small baitfish, minnows, crayfish or insects suggest a food supply. Check local regulations and access rules, since many streams are managed, and some waters are private. Local fisheries agencies often publish species information, and asking at a tackle shop is useful.
Identifying a fish from a photo
Species identification apps exist, and Fishbrain advertises photo recognition in its logbook. These tools can be wrong, so compare with a regional field guide or your state wildlife agency’s species pages, especially if rules differ by species or size.
What about nights?
Fish often shift locations after dark, usually toward shallower feeding areas. See night fishing in freshwater. The moon can influence timing as well, covered in how the moon affects fishing.
