Guernsey Dam

Guernsey Dam is two miles upstream from Guernsey, WY. From Interstate 25, take U.S. 26 east toward Guernsey. Turn north onto WY 317 (Lake Shore Dr.), which goes to the dam and continues over it. Lake Guernsey State Park may be accessed from WY 317 on the south, or WY 270 from the north. The park grounds are open 24 hours a day, year round, weather permitting; the museum is open May 1-September 30. The park offers a variety of recreational activities, including camping and fishing; there is a daily use fee ($4 for Wyoming residents; $6 for non-residents).
