Finding Fishing Spots: Charts, Reefs and Homework
Part of Core Skills · All fishing tutorials
Every good spot on the water was somebody’s homework first. The captains who always seem to be on fish are not lucky — they read charts at the kitchen table, work the public reef lists, and keep notes on every trip until the map in their head is worth more than the electronics on the console. The good news is that the core sources are free, public, and sitting there for anyone willing to spend an evening with them.
This page covers how to read a nautical chart for fishing features, where Florida publishes its artificial reef coordinates, which free tools put charts on your phone, and how to keep a spot log of your own.

Reading a Chart
A nautical chart is a depth map, and fish live on its shapes. Start with the contour lines: where lines crowd together, the bottom drops fast — a ledge or channel edge — and where they spread out, the bottom is a gentle slope or flat. Fish hold on the breaks: the edge of a shipping channel where it falls from 15 to 40 feet, the rim of a grass flat where it drops into a trough, the contour that wraps around a point. Follow a single contour line along a shore and you are tracing the path traveling fish use.
Then read the bottom labels. Charts mark bottom type in shorthand — S for sand, M for mud, G for gravel, rky for rocky — and rock near a contour break in Florida usually means live limestone bottom, which means reef fish. Wrecks and obstructions are charted with their own symbols and often a surveyed depth; every charted wreck symbol within your boat’s range is a candidate spot. Inshore, the chart’s flats, channels, and mangrove shorelines read the same way: the deep side of a point, a channel bend with an eddy, a hole in the middle of a flat. You are not memorizing the chart — you are learning to see the three or four shapes that hold fish and recognizing them anywhere.
FWC Reef Listings
Florida makes the offshore half of this easy. The state and counties sink artificial reefs — concrete modules, bridge rubble, culverts, reef balls, whole vessels — and FWC publishes the coordinates for them, by county, free, through its artificial reef program pages. Each listing gives the reef name, the lat/long, depth, and what was deployed and when. Load the numbers for your county into your GPS or chart app before the trip, sorted by distance from your inlet, and you have a season of candidate spots. New deployments go in every year, and recently placed reefs often fish well once life colonizes them. Treat the published numbers as the center of a search area, not a pin: circle the site slowly with the fish finder out a hundred yards in each direction, because material spreads and the best pile is not always the listed one. Our walkthrough on reading a fish finder shows what those piles look like when you find them. The reef listings and every species rule you will fish under both live under the same roof — our Florida fishing regulations hub links the state’s resources together.
Free Chart and Phone Tools
You do not need a paid chartplotter subscription to do this homework. NOAA’s charts are free to view online and cover every navigable Florida waterway in full detail. Several free and freemium phone apps put those charts, satellite imagery, and the public reef waypoints in your pocket; satellite view alone is a spot-finding weapon inshore, because it shows grass flats, sand holes, dock lines, and channel edges you would never see from the boat at water level. Spend your chart time zoomed into water you can actually reach, and mark candidates generously — a list of twenty maybes, tested over a season, becomes five proven spots.
Keeping Your Own Log
The last piece is memory, and paper beats yours. Keep a simple log — a notes app is fine — with the date, spot, tide, wind, water temperature if you have it, and what you caught or did not. Patterns you cannot see in a week jump out in a season: this ledge only produces on an outgoing tide, that flat lights up two days after a front. Mark spots honestly — a waypoint where you caught nothing twice in good conditions is information too.
Log ethics matter. Spots you find yourself are yours to share or not, but a number somebody gave you in confidence is theirs; passing it on burns the source and crowds the spot. And fish public reefs with the expectation of company on weekends — arrive early, anchor courteously, and remember the reef was published for everyone. The anglers who guard their homework and respect other people’s end up with the best maps on the dock.

Homework ends at the dock; the tools take over from there. Check the What’s Biting calendar to point your spot list at the species running this month, and let What Should I Target? narrow it by coast and season. When the chart work puts you over a new reef, reading a fish finder confirms what is actually down there before you drop a line — and before anything goes in the cooler, the seasons and limits on the regulations hub keep a good spot from becoming an expensive one.
