Ask the water
Depth charts, fish records, boat ramps and a bite forecast — one assistant that reads our own surveys, not the internet.
Built from FWC, USGS and NOAA public records
/What we know about every water
Not a promise — a live example. This is Lake Okeechobee exactly as our pipeline sees it: surveyed depths, ramps, campgrounds, water chemistry, stocking and a bite forecast. How we measure all of it →
What kind of water
A lake, a river and a swamp ask for different tackle and a different day. Start with the one you want.
What is biting near you right now?
Tap the button — we will find the closest mapped waters, tell you what is biting there and how to drive to the ramp.
Works in mapped states; elsewhere we will say we are still waiting for data.

A 680-Pound Marlin and $1.47 Million: How the Sea Birds Hooked the Ultimate Championship
OCEAN CITY, Md. — It was a week that will go down in sport-fishing history. The New Jersey Sea Birds didn't just win the SFC Atlantic Division Championship—they pulled it off in…
Where the numbers come from
We show depths, stocking and water chemistry. Fair questions to ask before trusting any of it.
Water chemistry is refreshed monthly. Stocking records follow the state schedule. Depth surveys change rarely — some go back decades, and the survey date is on every water page. The bite forecast is recomputed hourly from current weather.
Soundings and survey lines from three sources are assembled into one set of closed depth bands with a single scale. Sources measured from different datums are never mixed — what was left out is recorded on the water itself, so the gap is visible rather than silently filled.
Pressure and its trend, wind, cloud cover, air and water temperature, and moon phase, hour by hour. The score shows which part helped and which hurt — it is a weather-weighted estimate, not a promise.
Because nobody surveyed them. Florida has 5,466 named waters and far fewer surveys. We publish what exists and leave the rest blank rather than guessing — an invented depth is worse than none.
No. They are assembled from public surveys with known gaps and are meant for finding fish, not for taking a boat through. Use official nautical charts for navigation.
