Plans
Browsing is free without an account. Plans differ in how many gages you can track, whether you can run monitors, and how much reporting and history you get. Current tiers and prices are on the plans page.
How the limits work
- Tracked-gage cap. Each plan sets how many gages you can track at once. Untracking frees a slot immediately.
- Monitors. Paid plans include monitors; tier sets how many can be armed at once. Monitors attach to tracked gages, so the tracked cap is the outer bound.
- Archive restore. Plans with archive access can pull a tracked gage's full period of record out of long-term storage for deep-history analysis.
- Reporting workbooks. The multi-gage data, visualization, and statistics workbooks and the flow-conditions PDF are available from the middle tier up.
- API sources. API access follows the same source limits as the site.
What never changes with tier
- Exploring all gages and their public detail pages.
- The underlying data — readings are public at their sources, and every gage page links to its agency record.
- The analytics themselves: charts and statistics are computed the same way for everyone.
