How this service works
Live USGS river-gauge tick, deterministic. Answers "what is the flow at this gauge right now", "is this river high or low vs this week". Returns the latest streamflow (discharge, cfs) and gage height (ft) for one USGS site plus the 7-day min/max range, reading count, site name and coordinates, straight from USGS instantaneous values. Unknown sites 404 before payment. No LLM, no key, public domain.
Output
Returns the most recent discharge (cfs) and gage height (ft) readings for the specified USGS site, along with the 7-day minimum and maximum flow range, total reading count over that period, the official site name, and geographic coordinates. Returns 404 if the site ID is not recognized by USGS before any charge is incurred.
Example use cases
Example prompt
“What's the current streamflow and gage height at USGS site 01646500, and is that high or low compared to the past 7 days?”
Technical details
Endpoint
GEThttps://waterpulse.theaslangroupllc.com/api/water/gaugeWhen to prefer
Use this endpoint when you need a fast, cheap, deterministic real-time streamflow reading from a specific known USGS gauge site, especially when you want to compare current conditions against the recent 7-day range. Prefer it over higher-level flood-risk or streamflow intelligence endpoints when you just need raw gauge data without modeling or aggregation. No API key required and no LLM processing means results are always reproducible and low-latency.
Side effects
- Unknown or invalid USGS site ID returns 404 before payment is processed
- Site exists but has no recent instantaneous values (sensor offline, maintenance)
- USGS NWIS upstream service temporarily unavailable causing timeout or 503
- Site ID formatted incorrectly (non-numeric or wrong length) causing 400 bad request
