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 Jackson Lake.

Is it worth fishing Jackson Lake today?

5 out of 10 — picky. Work for it. The strongest stretch is 10:40 AM–12:40 PM. That number is worked out fresh each morning from the solunar windows, the pressure trend, the water level.

What time should you fish Jackson Lake?

Today's major windows run 10:40 AM–12:40 PM, with minor windows at 4:47 AM–5:47 AM and 5:19 PM–6:19 PM. Sunrise is 7:28 AM and sunset 6:50 PM. A major landing on first or last light is the stretch worth setting an alarm for.

What is the water temperature at Jackson Lake?

No gauge on Jackson Lake measures it, so this is an estimate: roughly 51.5°F, worked out from the 7-day mean of air temperature at NOAA weather station KJAC (Jackson, Jackson Hole 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 Jackson Lake right now?

6733.9 ft, the reading for September 30 from the Jackson Lake and Jackson Lake Dam (JCK) gauge run by the USBR, which publishes one value a day. Over 24 hours it is down 0.14 ft.

Are water levels rising or falling at Jackson Lake?

Falling. The lake is down 0.14 ft in 24 hours and down 0.14 ft over the week. Over the last 2 days it has held between 6733.9 and 6734.04 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 Jackson Lake?

That is a health question and it belongs with the state, not with us. WY publishes fish consumption advisories through its health or environmental agency, and those are the ones that count. We give no eating advice.

Do you need a licence to fish Jackson Lake?

Yes. A Wyoming fishing license covers this water, required from age 14. WGFD sets the rules and is the one that counts.
