Lewis and Clark State Park is a public recreation area occupying 490 acres (200 ha) on the north shore of the far western, upper reaches of Lake Sakakawea in Williams County, North Dakota. The state park, which is 19 miles east of Williston, is used for fishing, boating, camping, and picnicking. 
The park is named for Meriwether Lewis and William Clark, the leaders of the Corps of Discovery, which camped near here on April 17, 1805.  The North Dakota state parks department added three park units on Lake Sakakawea after the state legislature authorized the leasing of land from the U.S. Army Corps of Engineers in 1971. Lake Sakakawea and Lewis and Clark state parks were established in 1973; Fort Stevenson State Park near Garrison was established in 1974. 
The park has a marina with slips for rental, a swimming beach, and more than eight miles of multi-use, non-motorized trails. Overnight accommodations are available at a 73-site campground and two camping cabins.
