At nearly 1.6 million acres, Wood-Tikchik State Park is the largest state park in the nation. This one park encompasses nearly half of the State Park land in Alaska and 15 percent of all state park land in the United States. The park's acreage is quite diverse and includes 12 lakes, over 1,000 acres, rivers up to 60 miles in length, mountains exceeding 5,000 feet in elevation, and extensive lowlands.

The Lakes of Wood-Tikchik
Wood-Tikchik State Park is named for its two systems of large interconnected clear-water lakes located in southwest Alaska, just north of Dillingham. The southern lakes, the Wood River system, drains into Bristol Bay via the Wood River. The northern Tikchik Lake system drain into Bristol Bay by the Nuyakuk and Nushagak Rivers.

Wood-Tikchik State Park was created in 1978 for the purposes of protecting the area's fish and wildlife breeding and support systems and to preserve the continued use of the area for subsistence and recreational activities. The land and water in this region are traditional grounds for subsistence fishing, hunting, and gathering. These activities are an integral part of the culture in this region and provide not only food but a cultural tie to the land.
