Map of USGS gauge 01656903 and the river around it
Where FLATLICK BRANCH ABOVE FROG BRANCH AT CHANTILLY, VA sits.
Within Virginia DWR's comfort range. Water 65.1°F now; the highest in the last 24 hours was 65.1°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: 0.87–3.5 ft³/s (middle half of 19 years of record). Now: 1.85 ft³/s, normal.
Normal for this date. 1.85 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 19 years of record (2008–2026): 10th 0.62, 25th 0.87, median 2.5, 75th 3.5, 90th 9.6 ft³/s.
Daily means on record for Nov 5: lowest 0.38 ft³/s, highest 55.4 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.
Turn Around Don't Drown (National Weather Service)Dissolved oxygen 8 mg/L at Nov 5, 8:00 PM EST; 7-day range 6.4–14.3 mg/L
Enough oxygen for coldwater fish: 8 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 7.9 at Nov 5, 8:00 PM EST; 7-day range 7.7–8.7
Within EPA's freshwater range: pH 7.9 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 10.8 FNU at Nov 5, 8:00 PM EST; 7-day range 0.4–10.8 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 488 µS/cm at Nov 5, 8:00 PM EST; 7-day range 474–494 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 1.13 ft stage, 20 ft³/s at Nov 5, 8:00 PM EST (NWS gauge CTYV2; its stage datum can differ from the USGS gauge height).
