ABSTRACT

Linking U.S. and Canadian Border Waters: Seamless Digital Maps of Surface Waters Completed Along the Canada and United States International Boundary   [open pdf - 89KB]

"Clearer views of waters along the U.S. and Canadian border are now possible with new seamless digital maps. These maps make it easier to solve complex water issues that require a thorough understanding of drainage systems on both sides of the International Boundary. 'In the past, cross-border maps were not always accurate, but now these new digital maps are fully linked across the entire U.S. and Canadian border,' said Peter Steeves, physical scientist with the USGS [U.S. Geological Survey]. 'This cooperative project allows scientists on either side to look at the water just as nature does, irrespective of the artificial line separating the two nations.'Developed cooperatively by both countries […] , the digital maps make tackling difficult issues more effective. For example, levels of phosphorous flowing from Lake Champlain in Vermont into Quebec can now be better understood; flooding in the Red River Valley (which flows north from Minnesota and the Dakotas into Manitoba) can be traced; salmon fisheries in the Columbia River Basin in the Pacific Northwest can be efficiently restored; and understanding localized water use and water availability all along the border is now improved."
