I am "Borrowing this from Washington county's site....
Owned by the U.S. Bureau of Reclamation, maintained and operated by Washington County, the Park features numerous picnic areas, two boat launching facilities, a fully stocked lake for fishing, more than 15 miles of hiking trails, and observation decks for wildlife and bird watching. Since the creation of Henry Hagg Lake in the mid-1970s, Washington County, the Bureau of Reclamation, and the Washington County Elks Lodges have shared a commitment to make the Park user-friendly to every visitor. Located just 25 miles southwest of Portland, resting at the base of Oregon's beautiful coastal range, Hagg Lake offers visitors the best of outdoor recreational activities.
