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 9:56 AM–11:56 AM. 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 9:56 AM–11:56 AM and 10:20 PM–12:20 AM, with minor windows at 2:23 AM–3:23 AM and 6:19 PM–7:19 PM. Sunrise is 6:47 AM and sunset 8:19 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 water temperature. US reservoir gauges report height, not temperature — so rather than estimate it, this page leaves it out and leans on the windows and the pressure trend instead.
What is the water level at American Falls Reservoir right now?
4314.03 ft, the reading for August 23 from the American Falls Reservoir and Dam (AMF) gauge run by the USBR, which publishes one value a day. Over 24 hours it is down 0.57 ft.
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.

No one types these in by hand. If a source goes quiet, the page says so instead of showing you yesterday.
