Reading Nov 5, 7:00 PM MST · 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. We found no other gauge on the same river that publishes flow.
Water temperature, last 7 days: 169 readings from Oct 29, 8:00 PM MDT to Nov 5, 7:00 PM MST; ranging 47.1 to 51.6 °F; latest 49.3 °F.
USGS provisional data may be revised. Source: USGS instantaneous values.

Map of USGS gauge 06729470 and the river around it
Where SOUTH BOULDER CR AT FOREBAY NR ELDORADO SPRINGS CO sits.
Under CPW's 71°F line. Water 49.3°F now; the highest in the last 24 hours was 50.5°F. That is under the 71°F CPW uses for its closure criteria. “CPW recommends fishing early in the day to avoid peak afternoon temperatures.” “Anglers should use a handheld thermometer to test water conditions and move to cooler, higher-elevation waters once temperatures approach 71 degrees.”
CPW implements additional voluntary fishing closures on four Western Slope rivers (16 July 2026) (Colorado Parks and Wildlife)Species list not on file for this gauge. Check the Colorado Parks and Wildlife: Colorado fish stocking report · Colorado fishing rules and regulations.
Cold water. Water 49.3°F. NWS: “Cold shock can be just as severe and dangerous from water temperatures of 50-60°F (10-15°C) as it is from water at 35°F (2°C).” “Always wear a life jacket in and around the water.”
Cold Water Hazards and Safety (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 9.3 mg/L at Nov 5, 7:00 PM MST; 7-day range 8.8–10 mg/L
Enough oxygen for coldwater fish: 9.3 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, 7:00 PM MST; 7-day range 7.6–8.1
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 1.2 FNU at Nov 5, 7:00 PM MST; 7-day range 0.8–11.8 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 60 µS/cm at Nov 5, 7:00 PM MST; 7-day range 57–60 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, 7:59 PM MST; 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.
