Summary(Plain Language Summary, not published)
Within the framework of the groundwater mapping program of the Geological Survey of Canada (GSC), aquifers of the Richelieu/Lake Champlain transboundary watershed as well as the adjacent Yamaska watershed in Quebec are being characterized. The study area extends from the St. Lawrence River southward to Vermont and New York. The bedrock is the main aquifer. To help the understanding of groundwater flow dynamics, to assess hydraulic properties, and to develop transboundary groundwater flow numerical models, a 250,000 scale bedrock map has been compiled as a useful tool for the regional-scale hydrogeological project. The transboundary bedrock geologic map has been mainly created using existing digital compilation maps which have been standardized.
