Map of USGS gauge 15219000 and the river around it
Where WF OLSEN BAY C NR CORDOVA AK sits.
Federal guidance. Alaska Department of Fish and Game publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Alaska rule:
Under the federal 68°F line. Water 40.1°F now; the highest in the last 24 hours was 45°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: 8.6–34 ft³/s (middle half of 23 years of record). Now: 37.3 ft³/s, above normal.
Above normal for this date. 37.3 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 23 years of record (1965–2026): 10th 6.4, 25th 8.6, median 17, 75th 34, 90th 73 ft³/s.
Daily means on record for Nov 5: lowest 3.5 ft³/s, highest 85 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).
Falling over 24 hours: discharge down 47.3%, from 70.8 to 37.3 ft³/s. 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 Alaska Department of Fish and Game: Alaska fish stocking search · Alaska fishing regulations.
Cold water. Water 40.1°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)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.
NWS observed 10.5 ft stage, 46 ft³/s at Nov 5, 6:15 PM AKST (NWS gauge OSNA2; its stage datum can differ from the USGS gauge height).
NWS has not set flood categories for this gauge.
Graphical forecasts are not available during times of high water, forecast crest information can be found in the local WFO web page.

Checked Nov 5, 7:37 PM AKST; 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.
