Know the flow before you go. Flowy maps live streamflow from 15,000+ USGS river gauges across the United States — plus anonymous condition reports from people standing at the water, verified riverside. THE RIVER, LIVE - Every USGS streamgage on one beautiful map, colored by flow and labeled with current CFS - Tap any gauge: current flow, gage height, last-updated time, and a 14-day chart with 15-minute resolution - Animated river lines show you the water, not just the dots - Nearby flowing gauges surface automatically, with distance RIVERSIDE-VERIFIED REPORTS - Condition reports can only be posted within about 100 feet of a river or gauge — every report comes from someone who is actually there - Clear or muddy, glassy or choppy, rising or dropping, debris, crowds, wadeable — tap the words, done in 10 seconds - Each report is stamped with the weather at that moment - Anonymous by design: reports show a general area, never an exact spot WEEK IN REVIEW - Play back the past seven days of gauge conditions and watch rises move through whole basins FOR ANGLERS, PADDLERS, AND RIVER PEOPLE Fly fishing at dawn?
