CEDAR RIVER AT CEDAR FALLS, WA

Water temperature for trout, salmon and steelhead

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 48.9°F now; the highest in the last 24 hours was 48.9°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.”

Species

This gauge is on our page for Cedar River, but no agency page we read lists its species.

Safety

• Cold water. Water 48.9°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.
