Where the numbers come from
Every condition on this site comes from a free, public, authoritative source. Nothing is scraped from paywalled sites or bought from proprietary feeds.
Who we rely on
- NOAA
Tide predictions, water temperature and conditions from coastal and bay buoys.
- National Weather Service
Forecasts, wind, rain, and the weather and marine warnings shown on every spot.
- U.S. Geological Survey
River flow and water temperature on inland rivers, lakes and tailwaters.
- State fish and wildlife agencies
Size and creel limits, seasons, closures, trout stocking and the weekly fishing reports we quote. Each agency is the final word on its own rules, and every spot page links straight to it.
- State environmental agencies
Water-quality and swim advisories where a state publishes them.
Sunrise, sunset, moon phase and solunar periods are calculated from published astronomical formulas.
What we don’t do
- We don’t aggregate user-submitted catch reports.
- We don’t buy or license proprietary fishing-data feeds.
- We don’t rerank editorial content based on advertising relationships (see methodology).
