What's New in Big Buoy

1.5

September 1, 2026

RIVERS ARE HERE Every operational USGS river gauge is now in Big Buoy, free, for every user. Live stage, flow and water temperature for rivers across the country. • Nearby Rivers: a new tab on Spots & Buoys showing the closest gauges and what they're reading right now • Save any gauge to your spots, alongside your saltwater spots • Tap a gauge for stage, flow, water temp, recent trend and a 7-day chart • NWS flood categories, where the National Weather Service publishes them • Turbidity and dissolved oxygen on the gauges that report them • Gauges are searchable, same as buoys Rivers are worth watching even if you only fish salt. A big rain event pushes dirty freshwater downstream, and this is the easiest way to see what's coming. SHARPER WIND The wind map now runs at 0.25° and hourly, four times finer than the 1° field it replaces. Same map, a lot more detail close to shore. FIXES • Tidal river gauges no longer read as negative numbers. Flow reverses on an incoming tide, and it now shows as "399 cfs upstream" instead of "-399 cfs" • The Confirmation Email and Cancel buttons weren't responding • A saved coordinate link wouldn't open from a cold start • River gauge names now read the way you'd say them, not in USGS shorthand • Map data sources moved to an info button beside the map controls

User reviews

Sweet new tool!

All the tools at my fingertips in one app! Made for anglers, by anglers.

I NEEDED THIS

It’s everything I needed in one spot! beats having to keep a bugillion tabs open on my phone

Must Have

Awesome for figuring out where to go fish. Even better to pull up when they are biting to see what they are biting.

Best on the water forcasting app

Why check 2-3 different weather apps, when you can just check Big Buoy.. It’s unheard of to have water temps, waves, wind, solunar, chlorophyll overlay, sea surface overlay, and more; all easily accessible inside of just one app.

Makes life easier

Takes everything that was a pain to check and puts its all in one space
