Sandy Island Bald Eagle Sanctuary
Sandy Island provides critical habitat for wintering bald eagles that visit this region of the Mississippi River. The Mary Chambers Wiese platform located adjacent to the preserve, provides close-range viewing (complete with mounted scope) of the eagles and other birds.
Minutes from the St. Louis metropolitan area, just south of Winfield Lock and Dam, three miles east of Winfield, Missouri on Highway N.
Daylight
28 acres (includes a quarter mile of frontage along the Mississippi River just below the dam)
The preserve itself is closed to all visitation from November 1 to March 1, when the eagles are present.
Check the local weather forecast and dress accordingly. No special gear or clothing is recommended.
During the winter months, up to several hundred bald eagles use the preserve's cottonwood and silver maples trees for roosting. January and February are prime viewing times.
From the tall trees, the eagles scan the open water below the dam, where they dive to catch fish.
The Mary Wiese Observation Platform is located on Corps of Engineers property at the south end of Lock and Dam #25.
