Map of USGS gauge 10336780 and the river around it
Where TROUT CK NR TAHOE VALLEY, CA sits.
Under CDFW's 67°F line. Water 43.2°F now; the highest in the last 24 hours was 43.3°F. That is not over the 67°F CDFW uses for its voluntary “Hoot Owl” watchlist: “Sustained afternoon water temperatures exceeding 67 degrees Fahrenheit for trout fisheries could trigger additions to the list.” Water warms in the afternoon; check again later in the day.
CDFW Recommends “Hoot Owl” Practices for Fishing Inland Waters During Drought (15 July 2022) (California Department of Fish and Wildlife)Normal for Nov 5: 12–22 ft³/s (middle half of 66 years of record). Now: 14.2 ft³/s, normal.
Normal for this date. 14.2 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 66 years of record (1961–2026): 10th 9.8, 25th 12, median 17, 75th 22, 90th 25 ft³/s.
Daily means on record for Nov 5: lowest 5.8 ft³/s, highest 40 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 (+3.6% 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)Cold water. Water 43.2°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, 6:45 PM PST; 7-day range 9–10.8 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)Turbidity 2.6 FNU at Nov 5, 6:45 PM PST; 7-day range 1.7–12.1 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)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 5.44 ft stage, 14 ft³/s at Nov 5, 6:00 PM PST (NWS gauge TTVC1; its stage datum can differ from the USGS gauge height).
Forecasts are not available. Only observed stages are available for this point.
