Map of USGS gauge 09014050 and the river around it
Where GRAND LAKE OUTLET BLW CHIPMUNK LN AT GRAND LK, CO sits and our water's map point.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Colorado Parks and Wildlife uses are 71°F.
This gauge is on our page for Grand Lake, but no agency page we read lists its species.
USGS publishes no daily statistics for this gauge, so the reading is not compared with the record.
Steady over 24 hours (−0.2% 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.
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)pH 8.8 at Nov 1, 1:00 AM MDT; 7-day range 8.1–9.2; more than a day old
Within EPA's freshwater range: pH 8.8 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 1, 1:00 AM MDT; 7-day range 1–1.6 FNU; more than a day old
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 70 µS/cm at Nov 1, 1:00 AM MDT; 7-day range 66–74 µS/cm; more than a day old
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, 7:54 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.
