Map of USGS gauge 01589035 and the river around it
Where PATAPSCO RIVER NEAR ELKRIDGE, 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: 63–207 ft³/s (middle half of 16 years of record). Now: 62.9 ft³/s, below normal.
Below normal for this date. 62.9 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 16 years of record (2011–2026): 10th 50, 25th 63, median 94, 75th 207, 90th 520 ft³/s.
Daily means on record for Nov 5: lowest 40 ft³/s, highest 1,170 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 13.5%, from 55.4 to 62.9 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 13.5%). 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.
