Map of USGS gauge 11446220 and the river around it
Where AMERICAN R BL FOLSOM DAM NR FOLSOM CA sits, with 3 other gauges on the same river and our water's map point.
Under CDFW's 67°F line. Water 58.6°F now; the highest in the last 24 hours was 59.2°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.

Cold water. Water 58.6°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.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 7:15 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.
