About US Water Levels
The nation's premier digital directory for real-time hydrological data.
Our Mission
US Water Levels makes critical water data accessible, understandable, and actionable for everyone — from casual boaters checking lake conditions to environmental researchers monitoring drought patterns. We aggregate real-time sensor data from the United States Geological Survey (USGS) federal monitoring network and present it in a clean, user-friendly format.
Our Data & Expertise (E-E-A-T)
Data accuracy is our top priority. We do not guess or estimate. Our systems programmatically sync with the USGS Water Services API daily, pulling water surface elevation, discharge (flow rate), and temperature readings from active monitoring stations across the country.
Editorial & Review Process
Our programmatic models translate complex hydrological metrics (like discharge in cubic feet per second) into plain-English safety and activity advice. Each water body page provides contextual information about water temperature safety, flow conditions, and location data to help users make informed decisions about water-based activities.
What We Track
-
📊
Water Elevation — Surface level measured in feet above sea level, with full pool capacity percentages where available.
-
🌡️
Water Temperature — Surface temperature in °F with safety ratings for swimming, fishing, and water sports.
-
🌊
Discharge Rate — Water flow in cubic feet per second (cfs) for rivers and streams, with safety guidance for paddling activities.
-
📍
Location Data — GPS coordinates, county, nearest city, and interactive Google Maps with driving directions.
