Map of USGS gauge 01649500 and the river around it
Where NORTHEAST BRANCH ANACOSTIA RIVER AT RIVERDALE, MD sits.
Good trout temperatures. Water 63°F now; the highest in the last 24 hours was 63.3°F. That is under the 65°F Maryland DNR gives as preferred for trout (“Preferred temperatures, fishing is generally good”; “best chance for survival after release”). Water warms through the afternoon, so check again later in the day.
Trout Fishing Temperature Information (Maryland Department of Natural Resources)Normal for Nov 5: 24–64 ft³/s (middle half of 87 years of record). Now: 12.3 ft³/s, much below normal.
Much below normal for this date. 12.3 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 87 years of record (1939–2025): 10th 16, 25th 24, median 35, 75th 64, 90th 134 ft³/s.
Daily means on record for Nov 5: lowest 12 ft³/s, highest 766 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 10.8%, from 11.1 to 12.3 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.
Species list not on file for this gauge. Check the Maryland Department of Natural Resources: Maryland trout stocking · Maryland fishing regulations.
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 10.8%). 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.
Turn Around Don't Drown (National Weather Service)Dissolved oxygen 7.9 mg/L at Nov 5, 10:35 PM EST; 7-day range 7.9–13.4 mg/L
Enough oxygen for coldwater fish: 7.9 mg/L meets the 6.5 mg/L EPA sets for coldwater fish (other life stages; eggs and fry need a 8 mg/L minimum).
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)pH 7.5 at Nov 5, 10:35 PM EST; 7-day range 7.5–9
Within EPA's freshwater range: pH 7.5 is within the 6.5–9 range EPA gives for freshwater aquatic life.
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)Turbidity 1.6 FNU at Nov 5, 10:35 PM EST; 7-day range 1.4–17 FNU
Water clarity: Turbidity measures the relative clarity of water: higher means murkier. No agency publishes a fishing threshold for it; compare with this gauge's own recent readings.
Turbidity and Water (U.S. Geological Survey)Specific conductance 439 µS/cm at Nov 5, 10:35 PM EST; 7-day range 406–463 µS/cm
Dissolved ions: Specific conductance rises with the ions dissolved in the water. No fishing threshold is published for it; compare with this gauge's own recent readings.
Conductivity (Electrical Conductance) and Water (U.S. Geological Survey)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
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 0.41 ft stage, 10 ft³/s at Nov 5, 10:05 PM EST (NWS gauge RVDM2; its stage datum can differ from the USGS gauge height).
Forecasts are not available. Only observed stages are available for this point.
