Reading Nov 5, 7:40 PM EST · provisional USGS data
No flow at this gauge. USGS does not publish discharge here, so there are no flow statistics either; it reports what is shown. Flow on the same river: ROANOKE RIVER AT GLENVAR, VA (USGS 02054530, 2 miles away).
Water temperature, last 7 days: 185 readings from Oct 29, 8:40 PM EDT to Nov 5, 7:40 PM EST; ranging 53.4 to 60.6 °F; latest 60.1 °F.
USGS provisional data may be revised. Source: USGS instantaneous values.

Map of USGS gauge 02054550 and the river around it
Where ROANOKE RIVER AT RTS 639/760 AT SALEM, VA sits, with 5 other gauges on the same river and our water's map point.
Within Virginia DWR's comfort range. Water 60.1°F now; the highest in the last 24 hours was 60.6°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)This gauge is on the same river as our page for Roanoke River, but no agency page we read lists its species.
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 8.9 mg/L at Nov 5, 7:40 PM EST; 7-day range 8.5–12.1 mg/L
Enough oxygen for coldwater fish: 8.9 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 8.3 at Nov 5, 7:40 PM EST; 7-day range 8.2–8.7
Within EPA's freshwater range: pH 8.3 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 0.7 FNU at Nov 5, 7:40 PM EST; 7-day range 0.4–2.7 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 405 µS/cm at Nov 5, 7:40 PM EST; 7-day range 383–413 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.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 8:00 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.
