Tseriadun (pronounced serry-AH-dun) is popular with visitors stretching their legs on the miles-long beach, agate collectors (there's a reason the community calls it Agate Beach) and photographers intent on capturing the perfect shots of offshore rocks and headlands. Long ago, Native Americans lived at the site in cedar plank houses and hunted and fished in the mountains and rivers. Now, you can fish for rainbow trout and native cutthroat trout in Garrison Lake. Check the Oregon Department of Fish and Wildlife web site for fishing regulations and reports.
The Oregon Parks and Recreation Department purchased the property in 2003. In 2007, the department added a concrete box culvert that acts as an outlet for Garrison Lake to the ocean. The outlet stopped signicant erosion of cultural sites and limited flooding issues for adjacent property owners who live on the lake's shore.
