Hey Product Hunt! 👋

We’re the team behind ClearGauge (https://www.cleargaugerivers.com).

As river enthusiasts, we built ClearGauge out of a shared frustration: trying to decipher raw USGS NWIS streamflow tables on mobile phones at remote put-ins with 1 bar of service. Official tables provide raw numbers, but they lack immediate, practical context on whether a river is blown out, too low, or in the optimal range.

We created ClearGauge to make river telemetry clean, instant, and accessible:

• Real-time Streamflow: Instant CFS, gauge height (stage in feet), and 7-day flow trends formatted specifically for mobile.

• Flow Condition Verdicts: Automated status (Optimal, High Flow, Low Water, Flood Risk) calculated against historical percentiles.

• Live River Webcams: Curated directory of official USGS river webcams to inspect water clarity and bank levels before driving.

• Free Embed Widgets: Live flow badges that any outfitter, paddling club, or local blog can drop into their website in 30 seconds.

Built with Next.js, Tailwind CSS, MapLibre, and Postgres. It’s 100% free with no paywall, no ads, and no account required.

We'd love to hear from the Product Hunt community:

1. What local rivers, runs, or gauges do you paddle or fish that you'd like us to add?

2. Any thoughts or suggestions on the mobile flow metrics?
