Map of USGS gauge 01644375 and the river around it
Where LITTLE SENECA CREEK TRIBUTARY NEAR GERMANTOWN, MD sits, with 2 other gauges on the same river.
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.
Species list not on file for this gauge. Check the Maryland Department of Natural Resources: Maryland trout stocking.
Normal for Nov 5: 0.79–1.8 ft³/s (middle half of 22 years of record). Now: 0.44 ft³/s, lowest for this date on record.
Lowest for this date on record for this date. 0.44 ft³/s is below the lowest daily mean recorded on this date of daily mean flow for Nov 5 at this gauge over 22 years of record (2005–2026): 10th 0.49, 25th 0.79, median 1.1, 75th 1.8, 90th 3.1 ft³/s.
Daily means on record for Nov 5: lowest 0.46 ft³/s, highest 10.7 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 18.9%, from 0.37 to 0.44 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.
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 18.9%). 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.

Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 0.47 ft stage, 1 ft³/s at Nov 5, 9:55 PM EST (NWS gauge GMNM2; its stage datum can differ from the USGS gauge height).
