Description
This data resource provides hydrologic and water management information for the Grand River watershed. The watershed extends from the headwaters of the Grand River near Luther Marsh Reservoir to the mouth of the Grand River at Port Maitland on Lake Erie. This information is provided to the Library by the Grand River Conservation Authority (GRCA), however many of these layers are also available for download from the Grand River Information Network. The resource includes the following vector and raster grid data sets.
