About Maryland river runs
What does whitewater class mean?
The international whitewater scale (Class I–VI) rates a river's difficulty. I is moving water with riffles. II is straightforward rapids with clear channels. III requires complex maneuvers in fast water. IV is intense, powerful but predictable rapids requiring decisive boat handling. V is extremely long, obstructed, or violent rapids with significant hazard. VI is considered impossible to run.
Where does the Maryland streamflow data come from?
USGS streamgauges. Each Maryland paddle run is keyed to a specific gauge that paddlers and outfitters have agreed represents flow on that section. Gauges report every 15 minutes; we re-pull throughout the day.
What's a runnable level?
Run-specific. A creek that's classic at 200 cfs might be too low at 100 and dangerously flooded at 1,000. Always cross-reference with a guidebook or a Maryland paddling club for the run's accepted gauge ranges before launching.
Can I get an alert when a run hits prime flow?
Yes. Save any paddle run as a favorite in the Snoflo iOS app, set a flow window (e.g. "alert me between 800 and 1,500 cfs"), and you'll get a push the moment it crosses into range. Free with a Snoflo account.
Is this a substitute for local guidebooks and trip leaders?
No. Snoflo is informational. Always carry appropriate skills, gear, and a sober assessment of the day's flow. For high-consequence runs (Class IV+), paddle with people who know the run and never solo. American Whitewater is the authoritative source for U.S. river information.
