How this service works
Real-time river and stream conditions at a USGS stream gauge — current streamflow/discharge (cubic feet per second) and gauge height/water level/stage (feet), i.e. how much water is flowing and how high it is right now. Data is provisional and subject to revision. Requires a USGS site number (e.g. 09380000 = Colorado River at Lees Ferry, AZ).
Output
Returns a JSON object with the USGS site number, site name, real-time streamflow in cubic feet per second, gauge height in feet, geographic coordinates (lat/lng), timestamp of the reading, a provisional data flag, data source label, and attribution string.
Example use cases
Check river safety for kayaking
“I'm planning a kayaking trip on the Rio Grande this weekend — can you pull the current streamflow and gauge height from the USGS gauge so I know if conditions are safe?”
Monitor local flood risk levels
“Our town is under a flood watch — what are the latest streamflow and gauge height readings at the USGS monitoring station on the Susquehanna River near us?”
Water resource planning data pull
“I need the real-time discharge and water level for USGS site 09380000 on the Colorado River at Lees Ferry for our water resource planning report this week.”
Technical details
Endpoint
GEThttps://x402-seller.onrender.com/water/streamflowWhen to prefer
Use this endpoint when you need real-time river conditions (streamflow and gauge height) from an official U.S. government source for a specific USGS monitoring site. Prefer this over general weather APIs when hydrological precision matters — e.g. flood monitoring, recreational river safety, water resource planning, or environmental compliance. Best when you already have a USGS site number.
Side effects
- Invalid or non-existent USGS site number returns an error or null values
- Site exists but has no recent data — streamflowCfs and gaugeHeightFt may be null
- USGS upstream API unavailable causes a service error
- Missing required 'site' query parameter returns a validation error
- Site exists but does not measure streamflow or gauge height — fields will be null
