Lookingglass Creek

Lookingglass Creek is an 18 mi long stream in the U.S. state of Oregon, located in Union County. Starting in the Umatilla National Forest near Tollgate, it flows generally east then turns south to join the Grande Ronde River about 10 mi north of Elgin. The Lookingglass Fish Hatchery is located on the creek.

It is a local myth that several children went missing around Lookingglass Creek.

On March 29, 2024, a tanker truck carrying Chinook salmon smolt crashed after leaving the hatchery. The majority of the fish escaped into the river and survived.
