About these readings

Readings come from USGS real-time monitoring stations — 31 sensors are currently reporting a water temperature in Louisiana. Each figure is a point measurement at one sensor, usually on a river or stream — it doesn’t describe a whole lake or shoreline, and coverage varies across the state. Data is provisional and can be revised by the USGS.
