What part of the Assabet River National Wildlife Refuge was formerly used as a dumping ground by the Natick Laboratories until the 1980s?
Assabet River National Wildlife Refuge Assabet River National Wildlife Refuge, (formerly referred to as the U.S. Army's Fort Devens-Sudbury Training Annex), is a 2230 acre protected National Wildlife Refuge located approximately 25 mi west of Boston, and 4 mi west of the Eastern Massachusetts National Wildlife Refuge Complex Headquarters, along the Assabet River. It is located in portions of the Towns of Hudson, Maynard, Stow and Sudbury. The Assabet River National Wildlife Refuge consists of two separate pieces of land. The larger northern section is just north of Hudson Road, extending north to the Assabet River. The southern section is located to the south of Hudson Road. There is a visitor center located in the northern section, on Winterberry Way.
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.
