Unified, real-time flow data for the people who actually use it. Skip the patchwork of agency websites — every gauge, normalized, on one schedule.
Streamgage readings drive real decisions — diversion timing, fish passage, municipal supply, recreation safety, research models. Yet the data lives in silos. USGS NWIS, state ecology portals, private SCADA, water-district dashboards: each one a different URL, a different format, a different refresh cadence.
Aggregating across even a handful of sources usually means a folder of bookmarks, half-written scrapers, and a spreadsheet that goes stale by lunch. The data is public. The friction is the problem.
GageLog pulls every supported gauge on a fixed schedule, normalizes the readings to a single format, and exposes them through one consistent API and dashboard. Subscribe to the gauges you care about and stop chasing downloads.
If you check a gauge more than once a week, GageLog is for you. Water utilities tracking source flows. Hydrologists and researchers building models. Anglers and outfitters reading conditions before a trip. Irrigators timing diversions. Conservation teams documenting minimum flows.
The interface stays the same whether you're following one gauge or a hundred. Pick what matters, get readings at 15-minute resolution, export when you need to.
Connect to USGS NWIS, state agency portals, SCADA systems, and private sensors. Every supported gauge ingested on the same schedule, normalized to the same format, ready to query.
Pick any date range, any interval. Rolling averages, daily summaries, year-over-year comparison, anomaly flagging — all built in. Look at one gauge in detail or chart several side-by-side.
CSV export on every dataset and a documented REST API for everything else. Drop readings straight into a spreadsheet, notebook, or your own pipeline.
Sign up, pick your gauges, and start reading flow data without leaving the page.
