USGS Streamflow Scraper

US river & stream conditions from USGS Water Services — streamflow, gage height, water temperature and more, current or historical. Free keyless API. For anglers, hydrology & apps.

Monitor public USGS streamflow observations for selected stations and recent windows with bounded requests, retries, and deduplicated source records.

USGS NWIS Streamflow & Gage Height Monitor API by Site/State

malonestar/usgs-nwis-streamflow-monitor

USGS NWIS streamflow API: pull real-time river discharge (cfs) and gage height (ft) by site number or state. Flattens nested USGS WaterML-JSON into clean rows with change deltas and flood-stage threshold alerts. Keyless USGS Water Services data for irrigation, utilities, flood risk & hydrology.

Query USGS NWIS Instantaneous Values for bounded streamflow, discharge, gage-height, and water-monitoring observations by site or geography. Returns one source-linked row per site/parameter series with qualifiers, units, methods, and optional bounded history.

Extract real-time and historical water data from USGS Water Services including streamflow, gage height, groundwater levels, precipitation, and water temperature.

USGS NWIS River Streamflow & Fishing Conditions Scraper

jungle_synthesizer/usgs-nwis-river-streamflow-fishing-conditions-scraper

Pulls real-time discharge, gage height, and water temperature from every active USGS stream gage in any US state. Filters by state and parameter. Returns one record per gage with site metadata, the latest measurement, and derived flow condition (low/normal/high).

Get real-time river/stream gauge height and streamflow readings from official USGS monitoring stations, by state or specific site numbers. Sorted highest-first for fast high-water spotting.

USGS Water Services Scraper

parseforge/usgs-water-services-scraper

Scrapes USGS water data including instantaneous values, daily summaries, and groundwater levels by site code and parameter. Returns each observation as a flat row ready for analysis.
