Map of USGS gauge 01595000 and the river around it
Where NORTH BRANCH POTOMAC RIVER AT STEYER, MD sits, with 3 other gauges on the same river and our water's map point.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Maryland DNR uses are 65°F and 68°F.
Normal for Nov 5: 34–117 ft³/s (middle half of 70 years of record). Now: 80.4 ft³/s, normal.
Normal for this date. 80.4 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 70 years of record (1957–2026): 10th 22, 25th 34, median 70, 75th 117, 90th 183 ft³/s.
Daily means on record for Nov 5: lowest 13 ft³/s, highest 4,410 ft³/s.
Classes as USGS labels them (hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) ); percentiles from the USGS daily statistics (U.S. Geological Survey) (approved daily means; the reading is provisional and instantaneous).
Rising over 24 hours: discharge up 34.4%, from 59.8 to 80.4 ft³/s. Rising or falling means a change of more than 10% in discharge (or 0.2 ft of gauge height) over 24 hours; our rule of thumb, not a USGS class.
This gauge is on our page for North Branch Potomac River, but no agency page we read lists its species.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
Flood categories: action stage, minor, moderate and major flooding (National Weather Service)Rising water. Rising over the last 24 hours (discharge up 34.4%). Keep your way back to the bank in sight and watch the level while you fish. “Rising” is our rule of thumb: more than 10% in discharge or 0.2 ft of gauge height in 24 hours, not a USGS or NWS class.
Turn Around Don't Drown. “A mere 6 inches of fast-moving flood water can knock over an adult.” No flow number makes a crossing safe; if in doubt, stay out.
