Lanier Level: Lake & Dam Data

Lanier Level is the essential tool for boaters, anglers, and lakefront residents on Lake Sidney Lanier. Built with direct feeds from the U.S. Army Corps of Engineers and USGS, the app delivers the most accurate, up-to-the-minute data on lake elevation, dam operations, and weather conditions—all in a premium, easy-to-read dashboard.

Whether you're planning a weekend on the water, checking if your favorite boat ramp is open, or timing the bite below Buford Dam, Lanier Level gives you the insights you need to navigate the lake safely and confidently.

KEY FEATURES

Real-Time Lake Level
Instantly see the current surface elevation and exactly how many feet the lake is below or above the 1,071 ft full pool mark. Data updates hourly from official USGS gauges.

Buford Dam Operations
Monitor outflow, inflow, and the 24-hour release schedule. Perfect for anglers timing the tailwater bite and residents tracking water movement.

Lake Level Forecast
Look ahead with our proprietary 3-day forecast, combining recent elevation trends, weather predictions, and dam balance to estimate where the lake will be tomorrow and beyond.

Historical Trends
Analyze lake elevation over the past 7 days, 30 days, 6 months, or a full year. Compare current levels to historical averages to understand seasonal patterns.

Boat Ramp Status
Never drive to a closed ramp again. Check the real-time status of public boat ramps around the lake, including how many feet of margin remain before shallow water forces a closure.

Weather & Water Temp
Get local lake-side weather, wind speed, and Buford Dam tailrace water temperatures to plan your day perfectly.

Lanier Level uses official public data sources, including the U.S. Army Corps of Engineers CWMS and USGS gauge 02334430. Nothing is estimated or scraped from third parties—just reliable, actionable data for the Lake Lanier community.
