🔬 Data Methodology & Sources

Water temperature readings on this site are collected from USGS (United States Geological Survey) monitoring stations installed at lakes, rivers, and reservoirs across the country. Sensors measure water surface temperature in Celsius, which is converted to Fahrenheit for display. Data is retrieved and stored daily. Temperatures shown reflect the most recent available sensor reading for each water body, typically from the past 1–30 days depending on station reporting frequency.

⚠️ Water temperatures can vary significantly across a water body due to depth, currents, and time of day. Sensor readings represent conditions at the monitoring station location. Always exercise caution when swimming and consult local authorities for official safety advisories.
