USGS Water Scraper

Pulls live streamflow and gage height readings from USGS water monitoring sites through the public Water Services API. No login, no proxy, no browser.

Input

Field	Type	Notes
`sites`	array	Required. USGS site numbers, e.g. `["01646500"]`.
`parameters`	string	Comma-separated parameter codes. Default `00060,00065` (discharge and gage height).

Output

One row per site and measurement: siteCode, siteName, latitude, longitude, variableCode, variableName, unit, value, qualifiers, observedAt.

Notes

A site measuring two parameters produces two rows, so the row count is sites × reporting parameters, not sites.
USGS reports "no data" as -999999, not as null. Left alone that sentinel would poison any average or chart, so it is compared against the series' own noDataValue and mapped to null.
variableName arrives with HTML entities (ft³/s); they are decoded so the unit reads as ft³/s.
qualifiers of P means provisional — USGS data is unreviewed when fresh and can be revised later. Treat recent readings accordingly.

USGS Water Levels & Gauges — New API, Daily Values

extensive_necklace_zmp/usgs-water-levels-gauges

River and lake water levels, gauge heights, and streamflow for any US state or gauge list — daily values with recent history, freshness status, and validation — from the NEW official USGS Water Data API (the legacy API every other water actor uses shuts down in early 2027).
