Every fall, usually by October, a flock of white pelicans migrates south, possibly from as far north as Canada, to White Rock Lake to spend the winter months. Most often they can be seen at Dixon's Bay (a.k.a. Sunset Bay), on the east side of the lake, either sitting on the mudflats or sometimes on shore. Occasionally, they can also be seen floating on the water by the spillway, on the opposite end of the lake.
