Additional edits were made by the Region of Durham DMG Department for watercourses within the Urban River Valley areas (from Greenbelt 2017). These edits were to ensure the cartographic watercourse would remain within the limits of the Urban River Valley areas (as the process of smoothing the watercourse adjust the location of the linework in some places).</SPAN></P></DIV></DIV></DIV>

Wetlands are lands that are seasonally or permanently flooded by shallow water as well as lands where the water table is close to the surface; in either case the presence of abundant water causes the formation of hydric (moist) soils and has favoured the dominance of either hydrophytic (water loving) or water tolerant plants.</SPAN></P></DIV>
