Map of USGS gauge 01589197 and the river around it
Where GWYNNS FALLS NEAR DELIGHT, 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: 1.8–3.6 ft³/s (middle half of 27 years of record). Now: 1.45 ft³/s, much below normal.
Much below normal for this date. 1.45 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 27 years of record (1999–2025): 10th 1.6, 25th 1.8, median 2.8, 75th 3.6, 90th 6.3 ft³/s.
Daily means on record for Nov 5: lowest 1.29 ft³/s, highest 32.8 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).
Steady over 24 hours (+0% discharge). 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)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.
