Map of USGS gauge 12101100 and the river around it
Where LAKE TAPPS DIVERSION AT DIERINGER, WA sits.
Federal guidance. Washington Department of Fish and Wildlife publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Washington rule:
Under the federal 68°F line. Water 55.4°F now; the highest in the last 24 hours was 55.4°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: 175–947 ft³/s (middle half of 68 years of record). Now: 274 ft³/s, normal.
Normal for this date. 274 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 68 years of record (1959–2026): 10th 36, 25th 175, median 597, 75th 947, 90th 1,380 ft³/s.
Daily means on record for Nov 5: lowest 0.69 ft³/s, highest 1,830 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 (+0% 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 Washington Department of Fish and Wildlife: Washington trout stocking reports · Washington fishing regulations.
Cold water. Water 55.4°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 11.4 mg/L at Nov 5, 5:45 PM PST; 7-day range 9.6–13.2 mg/L
Enough oxygen for coldwater fish: 11.4 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 7.3 at Nov 5, 5:45 PM PST; 7-day range 7.1–9
Within EPA's freshwater range: pH 7.3 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 2.4 FNU at Nov 5, 5:45 PM PST; 7-day range 0.2–38.1 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)Specific conductance 60 µS/cm at Nov 5, 5:45 PM PST; 7-day range 60–64 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, 6:15 PM PST; 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.
