Getting started
Most of GageLog works without an account: every gage's detail page is public, with history capped at the last 7 days. An account removes that cap and adds tracking; paid plans add monitors, deep-history restores, and reporting workbooks.
What you can do without an account
- Search and browse all 9,100+ gages on Explore.
- Open any gage's detail page: today's readings, the last 7 days, anomaly detection, and the station map.
- Download a gage's readings straight from the operating agency — every detail page links to its source. The data is public; GageLog's value is normalization, analytics, and alerting on top of it.
Creating an account
Two ways in, both from the sign-up page:
- Google — one click, no separate password. If a GageLog account already exists under your Gmail address, signing in with Google links to it rather than creating a duplicate.
- Email and password — you'll receive an activation link
that must be clicked before the first sign-in. If it doesn't arrive,
check spam; the message comes from an
@gagelog.comaddress.
Both paths ask you to accept the Terms of Service once. API access via JWT is available to verified accounts — see Exports & the API.
A sensible first ten minutes
- Find a gage you know on Explore — search by river name, station ID, or state.
- On its detail page, open the Today tab and click "What is this?" under any chart. Every chart on the site explains exactly how it's computed.
- Track the gage (button in the page header). Tracked gages get a shared dashboard, side-by-side comparison, and are where monitors and archive restores attach.
- If your plan includes monitors, set one: the wizard suggests a threshold from the gage's recent range and backtests it against the last 30 days before you commit.
Units, timezone, and default anomaly thresholds are per-account settings —
change them in Settings. Charts and
exports follow your choices everywhere.
