What this means

Walleye, Largemouth bass
This gauge reports level but no water temperature, so depth calls stay open. Read the windows and the pressure trend instead.

That sits 39% of the way up the band it has held over the last 8 days, between 1.7 and 2.73 ft. Over the week it is down0.17ft.

Before you go

A WI fishing license covers this water. The state agency sets the rules and is the one that counts.

Questions people ask about Green Bay

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 Green Bay.

Is it worth fishing Green Bay today?
6 out of 10 — biting. Worth a cast. The strongest stretch is 12:24 AM–2:24 AM. That number is worked out fresh each morning from the solunar windows, the pressure trend, the water level.
What time should you fish Green Bay?
Today's major windows run 12:24 AM–2:24 AM and 12:49 PM–2:49 PM, with minor windows at 6:22 AM–7:22 AM and 8:01 PM–9:01 PM. Sunrise is 5:52 AM and sunset 8:00 PM. A major landing on first or last light is the stretch worth setting an alarm for.
What is the water temperature at Green Bay?
No gauge on Green Bay 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 Green Bay right now?
2.103 ft above LWD, read at 3:30 AM from NOAA CO-OPS station 9087077. Over 24 hours it is up 0.02 ft.
Can you eat the fish you catch in Green Bay?
That is a health question, and it is answered officially rather than by us. Wisconsin Department of Natural Resources, with the Department of Health Services publishes the fish consumption advisory covering these waters, where the Choose Wisely guidance covers every Wisconsin water, even untested ones, with tighter limits on specific lakes. Read it before you keep a meal — we give no eating advice.

Wisconsin DNR fish consumption advisory

What size fish can you keep in WI?
It depends on the species, and several have slot limits rather than a simple minimum. Open to harvest today: walleye, sauger and hybrids, largemouth and smallmouth bass (a combined total), northern pike. Seasons here change mid-year by agency order, so the status is re-checked every morning.

Where these numbers come from

The bay level comes from the Green Bay East CO-OPS station; the Fox River gauge at the river mouth adds water temperature and how much fresh water is pushing in.

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