What this tracks
This dataset records river mile markers and county boundaries along Tennessee’s navigable waterways.
Why it matters to you
If you operate a boat, kayak, or fishing business on Tennessee rivers, this data helps you pinpoint your exact location in case of emergencies or when reporting hazards. It also clarifies which county’s regulations apply to your stretch of river—critical for permits or waste disposal rules. For waterfront property owners, the mile markers help verify flood zone maps or docking rights.
How to read this data
mile_no — The distance in miles from a river’s confluence or origin (e.g., “50” means 50 miles upstream).

POINT_X / POINT_Y — GPS coordinates (e.g., “-88.0695329334, 36.6665185761”) to plot the marker on a map.
