A federal refuge running free eagle tours by bus every Saturday for six weeks, and a state agency that names a dozen reservoirs.
Every place below is one an agency itself describes for eagle viewing, with that agency named and linked. Where a federal agency wrote something worth reading, its words are reproduced exactly, because a US government work is in the public domain. Where a state agency or a company is the source, the fact is in our own words with the source named.
The Robert S. Kerr Reservoir on the Arkansas River
The refuge runs free eagle watch tours on a refuge bus from its headquarters, every Saturday across six weeks of late winter, with binoculars and spotting scopes provided and no booking needed. That is the most accessible offer of its kind in this inventory.
Run by US Fish and Wildlife Service
Great Salt Plains Lake
The refuge general information leaflet names January and February for both bald and golden eagles, at the Jet Recreation Trail, Cottonwood Point and the Harold F. Miller auto tour. The state agency separately describes this refuge as holding the largest winter gathering in Oklahoma, usually seventy birds or more.

Keystone Lake, a Corps of Engineers reservoir
One of a dozen places the state wildlife agency lists for eagle viewing. The Corps page for the lake says nothing about eagles at all, so this is the state agency describing a federal reservoir, which is the usual arrangement for winter eagle sites.
“Golden and Bald Eagles: January through February at Jet Recreation Trail, Cottonwood Point, and the Harold F. Miller Auto Tour”US Fish and Wildlife Service, Great Salt Plains National Wildlife Refuge general information leaflet. A US government work, in the public domain, quoted exactly.
Viewing sites in Oklahoma, with the Corps of Engineers locks and dams in the state drawn underneath. The coloured grid is where people have uploaded a verified bald eagle record to iNaturalist in December, January and February, brighter where more have been logged. It is a map of reports, not of birds: it thickens around car parks, boardwalks and towns because that is where observers stand, and it thins over roadless country whether or not eagles are there. It shows past reports rather than birds present today. Pins are public viewing sites an agency itself describes; grey dots are US Army Corps of Engineers locks and dams, drawn because open tailwater below a dam is the reason most of these sites exist.
The window for Oklahoma is numbers building from November and peaking in January and February, according to Oklahoma Department of Wildlife Conservation. That is a pattern across past winters rather than a forecast: how well a given year matches it depends on whether the water upstream actually freezes. A mild winter keeps the river open everywhere, the birds stay spread out, and the concentration this page is about never forms.
Time of day is the more reliable lever in any case, and it is the one thing every agency agrees on. The federal management guidance describes when eagles feed, and it is not the middle of the day.
“Avoid recreational and commercial boating and fishing near critical eagle foraging areas during peak feeding times (usually early to mid-morning and late afternoon), except where eagles have demonstrated tolerance to such activity.”US Fish and Wildlife Service, National Bald Eagle Management Guidelines, May 2007. A US government work, in the public domain, quoted exactly.
Read that as a viewing instruction rather than a boating one. The birds come off the roost hungry, fish hard in the first hours of light, and then spend the middle of the day sitting in a tree digesting, which looks exactly like an empty river to somebody who arrived at eleven. Late afternoon gives you a second, shorter window as they feed again before going back to roost.
Oklahoma is not a state people associate with eagles, and its wildlife agency has quietly built one of the better public offers in the country. Its own guidance says numbers begin rising in November and peak in January and February, and it lists a dozen lakes and refuges across the state, from the panhandle to the eastern reservoirs. The federal refuges do the rest. Sequoyah runs a free bus tour with optics provided, which removes almost every barrier to a first eagle trip, and Great Salt Plains is one of the few places in this inventory where a federal document names golden eagles alongside bald ones as something to expect, because the western half of the state is genuinely golden eagle country in a way the Mississippi valley is not.
Below is a reading of a public platform rather than a survey. It counts the research grade bald eagle observations members of the public have uploaded to iNaturalist for this state, by calendar month, across every year the platform holds. It is a count of reports. It measures how many people were out with a camera as much as it measures birds, so the shape is worth reading and the absolute numbers are not.

A staffed event is the easiest possible introduction to this: somebody has already found the birds, set up a scope on them and can tell you what you are looking at. Most agencies publish the dates only weeks ahead, so what follows names the organiser and the recurrence, and the organiser’s page carries the current date.
Every Saturday for six weeks in late winter, starting 9 a.m. at the refuge headquarters
Free, no pre registration, riding the refuge tour bus, with binoculars and spotting scopes available and a finish between noon and one.
The refuge page gives a day and month range without a year, so confirm the season with the refuge: US Fish and Wildlife Service
