Map of USGS gauge 01648010 and the river around it
Where Rock Creek at Joyce Rd Washington, DC sits.
Federal guidance. We found no the District of Columbia agency water-temperature line for trout anglers. The lines below are the National Park Service's, federal guidance, not a the District of Columbia rule:
Under the federal 68°F line. Water 60.3°F now; the highest in the last 24 hours was 60.3°F. That is under the 68°F at which the National Park Service, at Grand Teton National Park, recommends anglers stop fishing in the afternoon (“cease fishing at 2 p.m. when water temperatures are likely to exceed 68°F”). Water warms through the afternoon, so check again later in the day: “Carry a pocket thermometer to monitor water temperature.”
High water temperatures prompt fishing advisory in Grand Teton National Park (29 July 2022)Normal for Nov 5: 13–73 ft³/s (middle half of 14 years of record). Now: 14.8 ft³/s, normal.
Normal for this date. 14.8 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 14 years of record (2013–2026): 10th 11, 25th 13, median 25, 75th 73, 90th 299 ft³/s.
Daily means on record for Nov 5: lowest 9.96 ft³/s, highest 465 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 (+3.5% 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.
Species list not on file for this gauge. Check the District of Columbia fish and wildlife agency for what lives here.
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 9.1 mg/L at Nov 5, 10:35 PM EST; 7-day range 8.9–12.2 mg/L
Enough oxygen for coldwater fish: 9.1 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 7.7 at Nov 5, 10:35 PM EST; 7-day range 7.6–8.2
Within EPA's freshwater range: pH 7.7 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 1.3 FNU at Nov 5, 10:35 PM EST; 7-day range 0.9–3.3 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 646 µS/cm at Nov 5, 10:35 PM EST; 7-day range 596–648 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 1.23 ft stage, 15 ft³/s at Nov 5, 10:05 PM EST (NWS gauge RCJD2; its stage datum can differ from the USGS gauge height).
Forecasts are not available. Only observed stages are available for this point.

Checked Nov 5, 11:08 PM EST; readings refresh at most every 15 minutes and statistics daily. Provisional USGS data can be revised. Conditions change: re-check before you go. This is general guidance, not a fishing forecast, a safety guarantee or a statement about access.
