Questions people ask about American Falls Reservoir

Answered from the same readings as the rest of this page. Where we have no basis for an answer, there is no entry — spot-by-spot local knowledge is not something we can claim for American Falls Reservoir.

Is it worth fishing American Falls Reservoir today?
6 out of 10 — biting. Worth a cast. The strongest stretch is 10:49 AM–12:49 PM. That number is worked out fresh each morning from the solunar windows, the pressure trend, the water level.
What time should you fish American Falls Reservoir?
Today's major windows run 10:49 AM–12:49 PM, with minor windows at 4:57 AM–5:57 AM and 5:29 PM–6:29 PM. Sunrise is 7:36 AM and sunset 7:00 PM. A major landing on first or last light is the stretch worth setting an alarm for.
What is the water temperature at American Falls Reservoir?
No gauge on American Falls Reservoir measures it, so this is an estimate: roughly 62.3°F, worked out from the 7-day mean of air temperature at NOAA weather station KPIH (Pocatello, Pocatello Regional Airport). Checked against the lakes that do have a thermometer, that method lands within about 4.5°F of the real reading and was off by 8.3°F at worst. Treat it as a ballpark, not a measurement — and note the bite index above ignores it entirely, because an error that size would move the verdict as often as it would fix it.
What is the water level at American Falls Reservoir right now?
4309.56 ft, the reading for September 30 from the American Falls Reservoir and Dam (AMF) gauge run by the USBR, which publishes one value a day. Over 24 hours it is up 0.06 ft.
Are water levels rising or falling at American Falls Reservoir?
Rising. The lake is up 0.06 ft in 24 hours and up 0.34 ft over the week. Over the last 2 days it has held between 4309.22 and 4309.56 ft. Every figure here is a difference between two gauge readings, not a forecast — what the level does next depends on rain and on what the dam releases.
Can you eat the fish you catch in American Falls Reservoir?
That is a health question and it belongs with the state, not with us. ID publishes fish consumption advisories through its health or environmental agency, and those are the ones that count. We give no eating advice.

Where these numbers come from

Read at the dam on the Snake River by the Bureau of Reclamation once a day. No temperature sensor.
