Map of USGS gauge 01646305 and the river around it
Where DEAD RUN AT WHANN AVENUE NEAR MCLEAN, VA sits.
Within Virginia DWR's comfort range. Water 61.7°F now; the highest in the last 24 hours was 61.7°F. Virginia DWR: trout “are most comfortable in highly oxygenated water that doesn’t exceed 68 degrees in temperature.” It also warns that “Trout become stressed in water temperatures in the mid- to upper-60s”: on warm days, “consider fishing early in the morning for a few hours and then quitting.”
Safe Practices for Summer Trout Fishing (7 June 2022) (Virginia Department of Wildlife Resources)Normal for Nov 5: 0.44–1.2 ft³/s (middle half of 18 years of record). Now: 0.52 ft³/s, normal.
Normal for this date. 0.52 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 18 years of record (2009–2026): 10th 0.27, 25th 0.44, median 0.76, 75th 1.2, 90th 4.3 ft³/s.
Daily means on record for Nov 5: lowest 0.27 ft³/s, highest 24.6 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 20.9%, from 0.43 to 0.52 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 Virginia Department of Wildlife Resources: Virginia daily trout stocking schedule · Virginia freshwater 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 20.9%). 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.
Turn Around Don't Drown (National Weather Service)Dissolved oxygen 6.6 mg/L at Nov 5, 8:15 PM EST; 7-day range 6.6–10.2 mg/L
Enough oxygen for coldwater fish: 6.6 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 at Nov 5, 8:15 PM EST; 7-day range 7–7.2
Within EPA's freshwater range: pH 7 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 0.4 FNU at Nov 5, 8:15 PM EST; 7-day range 0.4–0.8 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 428 µS/cm at Nov 5, 8:15 PM EST; 7-day range 413–659 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 1.28 ft stage, 1 ft³/s at Nov 5, 8:25 PM EST (NWS gauge MDRV2; its stage datum can differ from the USGS gauge height).
Forecasts are not available. Only observed stages are available for this point.
