January 2026 Update: Eagle Nest Buffer Zone Established
New activity in an established bald eagle nest, located in an area below the Pensacola Dam main spillway, has prompted the Grand River Dam Authority to close access to the area, as it has done in previous years. A portion of the spillway area, popular as an off-roading destination, will also be closed to visitors to help protect the nest.
"We're seeing the same sort of activity on this nest that we have seen in previous years," said GRDA Corporate Spokesperson Justin Alberty, "so we appreciate the public's cooperation in giving the nest area a wide berth and obeying the signage."
Guidelines established by the United States Fish & Wildlife Service recommend closing access around nests to allow for a buffer zone of 330 to 660 feet between the nest and public access. The restricted area below Pensacola Dam is centered approximately three-quarters of a mile south of the main spillway. "Nesting area/no trespassing" signage designates the closure along with yellow perimeter tape and orange fencing.

Viewing Directions: To access Eagle Pass, follow Broadway Avenue south out of Langley to N4475 Road (the road below Pensacola Dam). Go east on N4475 until you cross a bridge, then turn right (south) onto the dirt road and follow it to the eagle viewing areas.
Bald eagles will hunt small fish, often taking them off the surface of the water or even stealing them from other birds. The best time to watch the birds feed is early in the morning.
Why Grand Lake
Every winter, American Bald Eagles migrate to Grand Lake to feed on fish in the tailwaters below Pensacola Dam. The reliable food source and open water make this one of Oklahoma's premier eagle viewing locations.
At peak season, dozens of eagles can be spotted in a single visit, perching in trees, soaring overhead, and diving for fish in the churning waters below the dam.
When to Visit
- Season: December through February (peak: January)
- Best Time of Day: Early morning and late afternoon
- Best Conditions: When floodgates are releasing water (more fish activity)
- Weather: Cold, clear days often bring more eagles

About Bald Eagles
The American Bald Eagle was removed from the endangered species list in 2007 after a remarkable recovery. Once decimated by DDT and habitat loss, eagles have made a strong comeback across North America.
Adult bald eagles are unmistakable with their white heads and tails contrasting with dark brown bodies. They have a wingspan of 6-7 feet and can weigh up to 14 pounds. Juveniles are brown all over and don't develop the iconic white head until age 4-5.
