Dewar Lakes DEW Line Station

Military conversion and technological obsolescence. The station was closed as part of the transition from the Distant Early Warning (DEW) Line to the new, more automated North Warning System (NWS). The end of the Cold War and advancements in satellite and radar technology made the extensive network of manned DEW Line stations redundant and economically unsupportable. Dewar Lakes was not selected for conversion into a new NWS Long Range Radar site.

The site is decommissioned, remediated, and abandoned. After its closure, the station, like many other DEW Line sites, was a source of environmental contamination, including PCBs, lead, and petroleum hydrocarbons. The Canadian Department of National Defence (DND) undertook a massive environmental remediation project called the 'DEW Line Clean-Up Project'. At Dewar Lakes, this involved the demolition of all buildings, removal of hazardous materials, and restoration of the landscape. The project for this site was completed in the early 2000s. The airstrip is no longer maintained, is considered closed, and is unusable for any regular aviation operations. The site is now an unpopulated, remote area with no remaining infrastructure.

Dewar Lakes was a critical component of North American continental defence during the Cold War. Designated as FOX-3, it was an Auxiliary Station in the FOX Main sector of the DEW Line, which stretched across the Arctic from Alaska to Greenland. Its primary mission was to detect incoming Soviet bombers and provide early warning to NORAD. The station operated powerful surveillance radars and communication systems. The gravel airstrip, approximately 4,150 feet (1,265 meters) in length, was essential for the station's existence. It facilitated the initial construction and was the primary means for logistical support, receiving supplies, equipment, and personnel via regular flights, often operated by military transport aircraft like the C-130 Hercules and chartered civilian planes.

None. There are no known plans or prospects for reopening the airstrip. Its remote location, the absence of any local population or economic activity, and the extreme cost of maintaining infrastructure in the High Arctic make its reactivation unfeasible. The military and civilian aviation needs of the region are met by other established airports and the automated systems of the North Warning System.
