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 or barge business, this data tells you exactly where you are on Tennessee’s rivers using standardized mile markers, helping you plan routes and meet delivery schedules. Anglers can use it to pinpoint fishing spots or navigate safely between access points. Emergency responders reference these markers during water rescues to locate incidents quickly.
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).
river_name — The waterway the marker belongs to (e.g., “Tennessee River”).
POINT_X / POINT_Y — GPS coordinates of the marker (e.g., longitude -88.069, latitude 36.666).
