What part of the Assabet River National Wildlife Refuge was formerly used as a dumping ground by the Natick Laboratories until the 1980s?
Fort Devens-Sudbury Training Annex The Fort Devens-Sudbury Training Annex was a former annex of Fort Devens that was operational from 1942 to the 1990s. It originally opened as an ammunition dump for the base, and old railroad lines and bunkers can still be seen in the area. It then functioned as a dumping ground for the Natick Laboratories until the 1980s. In the 1990s, the site was cleaned up and turned into the Assabet River National Wildlife Refuge.
Dworshak National Fish Hatchery Dworshak National Fish Hatchery is a mitigation hatchery located on the Clearwater River within the Nez Perce Reservation near Orofino, in north-central Idaho. It was constructed in 1969 by the Army Corps of Engineers, and is co-managed by the U.S. Fish and Wildlife Service and the Nez Perce Tribe. The hatchery is one of the largest combination producers of anadromous (migratory) fish in the world. These fish make a 1000 mile round trip to the ocean and back to spawn in the Clearwater River. The Dworshak Dam blocks access to the historical spawning areas on the North Fork-Clearwater River for the steelhead, and it is too high for a fish ladder.
