USGS 15300300 · Alaska · reports discharge (live), gauge height, water temperature

Caution: High water: fish the edges; wading risky

Flow 1,320 ft³/s: much above normal (over the 90th percentile) for Nov 5, over 29 years of USGS record. U.S. Geological Survey
The agency list on file names no trout here; for coldwater fish: 39.6°F now, 39.6°F at most in 24 hours: under the National Park Service's 68°F line (federal guidance; no Alaska line found). National Park Service
Below NWS action stage (official NWS category). That is not a statement that wading is safe. National Weather Service
Cold water, 39.6°F. NWS: cold shock is dangerous at 50-60°F and colder; “Always wear a life jacket in and around the water.” National Weather Service

What the agencies suggest

Fish the softer water along the banks. During periods of high water, fish move towards the banks to find calmer water and lower velocities Pennsylvania Fish and Boat Commission
Don't wade where you can't see the bottom. Wading and boating should be avoided if waters are running high and muddy and the streambed is not visible Pennsylvania Fish and Boat Commission
Or fish a lake instead. If stream conditions are not favorable, consider fishing at a lake Pennsylvania Fish and Boat Commission

General guidance from the readings and the published lines named above, not a fishing forecast. Local rules and closures come first.

Conditions for fishing general guidance

Water temperature for trout, salmon and steelhead

The agency list on file names no trout, salmon or steelhead here; these are the lines for coldwater fish if you are after them.

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 39.6°F now; the highest in the last 24 hours was 39.6°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.”
