Pattison State Park
Interfalls Lake is a flowage and water depths often change after rain. Interfalls Lake is 27 acres in size, with a maximum depth of 13 feet and mean depth of seven feet. Pattison's 300-foot sand beach on Interfalls Lake offers an excellent sunning area, beautiful bathhouse and adjacent picnic area. The beach is unguarded. Don't swim alone and watch children closely near the water. Swim only at the designated beach; swimming outside the lifeline, in the river or at the waterfalls is dangerous.
