Public registries only, and nothing else. Waters and shorelines: the USGS National Hydrography Dataset, refined with OpenStreetMap where it draws the shore better. Depths: NOAA charts, soundings and bathymetric grids, US Army Corps channel surveys, and state surveys — Florida's FWC and St Johns water district, the USF Water Institute, Georgia DNR, the Geological Survey of Alabama. Water chemistry: the Water Quality Portal, run jointly by USGS and the EPA. Boat ramps and camps: FWC and RIDB. Photos: Wikimedia Commons, with the author and licence shown. Every water page names the exact source of its own numbers.

FAQ
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 are assembled into one set of closed depth bands on a single scale. Sources measured from different reference levels are never mixed — a depth counted from the sea and a depth counted from the lake surface are different numbers, and averaging them would invent a lake that does not exist. What we left out, and why, is printed on the water's own page rather than quietly dropped.
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. We hold 78,208 waters and 12,931 of them have a depth chart. Surveys are done by agencies, not by us: where one exists we publish it, and where none exists we leave the field blank rather than guessing. An invented depth is worse than no depth — it is the one number a person might actually act on.
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.
