Last data update: July 19, 2016 Watercourses are defined as an identifiable depression in the ground in which a flow of water regularly or continuously occurs. Both natural and artificial channels comprise this network in the Lake Simcoe Protection Plan watershed. This layer was originally created from 2002 break lines, 2002 orthophotography and OBM watercourse mapping. Updates have been made based on 2007, 2008 and 2009 orthophotography as well as site and field visits. Timing restriction information was acquired from MNR. Stream order was determined by the Strahler method using MNR's WRIP toolbar.
