When rivers freeze, bald eagles can gather where fish remain accessible. Find public viewing locations, check the latest weather, and read actual observations when available.

Why this spot?
Winter water and feeding habitat.
Where to look
Stay at the public overlook and scan distant trees.
Cold air can create an opportunity for concentrations near flowing water. It never proves river ice, a dam tailwater opening or an eagle sighting.
02 / Evidence, not a forecast
What are observers actually counting?
Select a supported lock-and-dam location for the latest machine-readable Corps count. Counts are snapshots from the observation date—never a promise about today.
National Eagle Center staff and volunteers count winter eagles weekly at 13 Upper Mississippi locations. Reports can be affected by visibility and survey timing.
When still water freezes, eagles may hunt near open river reaches, dams and confluences. A cold forecast alone cannot identify those openings.
02 · Time your visit
Morning and late day
Wisconsin DNR recommends early morning, roughly 8–11 a.m., and the period before dusk. Conditions and feeding activity vary.
03 · Keep your distance
Let wild birds stay wild
Watch from designated public overlooks or your parked vehicle. Never bait eagles, approach roosts or walk onto river ice; leave if birds react to you.
04 / Field questions
Before you set out
When is the best season for winter eagle gatherings?
Many Midwest sites have a winter gathering window from mid-December through early March. River ice, flow and weather can shift the timing. Resident eagles can be visible all year.
Can this page tell me if eagles are there right now?
No. It shows public viewing options, live NWS weather and historical dated surveys at supported locations. An unreported day or missing count cannot be interpreted as zero or as a sighting.
Is open river water guaranteed below every dam?
No. Tailwaters often offer feeding habitat in winter, but hydraulic conditions, ice and access are site-dependent. Check the facility operator before travel.
Why does a bald eagle look brown rather than white-headed?
Young bald eagles can be mottled brown with irregular white patches. The familiar white head and tail develop with maturity. Do not mistake an immature bald eagle for another species based on head color alone.
