Clear Lake Bird Refuge is located south of Delta, off of Hwy 257. It consists of a series of small lakes and ponds that are used heavily by migratory waterfowl and other birds and animals.
Snow Geese in particular favor the refuge and congregate there in great numbers. Every February thousands of these beautiful white birds use the fields and waters around the Clear Lake area as a rest stop on their northern migration. No other site in Utah offers the chance to see so many snow geese in one place. The sight and sound of thousands of white geese in the air and on the water in such a concentrated condition has got to be one of the most incredible wildlife experiences available.
