About Tennessee Lake Levels

Our Mission

Tennessee Lake Levels provides real-time and historical water level data for major TVA-managed lakes in Tennessee. Our goal is to help recreational users, boaters, and anglers make informed decisions about their water activities.

Data Sources

Water level data is sourced directly from the Tennessee Valley Authority (TVA) public API. The TVA manages water levels across its reservoir system for multiple purposes including flood control, power generation, navigation, and recreation.

Water temperature data is provided by the United States Geological Survey (USGS) Water Services API. Temperature readings are collected from USGS monitoring stations on rivers feeding into each lake, providing real-time water temperature measurements to help plan your water activities.

Lakes Covered

• Douglas Lake - 30,400 acres, 555 miles of shoreline
• Cherokee Lake - 28,780 acres, 463 miles of shoreline
• Norris Lake - 34,200 acres, 809 miles of shoreline

Data Updates

Water level and temperature data is updated every 15 minutes from TVA and USGS sources. Historical data is aggregated daily, providing multi-year trends for pattern analysis. The system automatically collects and validates data to ensure accuracy.

Technology

This website is built with Astro and React, using modern web technologies for fast, static site generation. Interactive charts are powered by Recharts, providing detailed visualization of water level trends.
