Low-Flying Helicopters Mapping Underground Water In Southern Alberta
Southern Alberta: You may notice some unusual helicopter flights over southern Alberta until the end of March. The flights, to map groundwater supplies, began on Saturday, and will cover 18-thousand square kilometres of terrain.
The helicopters will be flying low -- just 75-metres from the ground -- and towing a ring shaped radio receiver. The airborne geophysics, uses electromagnetic waves to help locate underground water supplies by measuring the electrical properties of the earth, rock and water below ground level. The waves are harmless to people and animals and will not interfere with cell phones or other electronic devices.
Mapping will cover an area from Calgary and Drumheller to Fort Macleod and Vauxhall. The flights will be conducted around the outskirts of communities and will avoid flying directly over homes and barns.
The survey is part of a multi-year provincial groundwater mapping and inventory program commissioned by the province and the Alberta Geological Survey and is one of the key actions outlined in Alberta's Water for Life Action Plan. Mapping should be complete by March 31st and results will help the province protect and manage water resources.
