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.
Crawfish Lake (Washington) Crawfish Lake ( ) is a small lake located 15 mi northeast of Omak, Washington. The lake has a surface area of 80 acre and is located at 4475 ft above sea level. The northeast portion of the lake borders the Okanogan National Forest, and the south half is on the Colville Indian Reservation. Most of the property along the shoreline of the lake is privately owned, with a US Forest Service campground occupying the northeast side of the lake. Motors have been prohibited on the lake since 1996. The lake is used mainly for fishing, rowing, canoeing, kayaking and swimming. The lake once contained many crawfish but the state has recently poisoned it to contain the native water reed and thus kill the crawfish.
