Description:
The Contemporary Mapping of Watercourses dataset is a surface water inventory created in partnership and jointly owned by the Niagara Peninsula Conservation Authority and the Niagara Region. The dataset currently corresponds to the extent of the Regional Municipality of Niagara until such a time that NPCA can complete interpretation and development of the inventory throughout its watershed jurisdiction (large scale source geometry exists). The objective of this dataset is to provide a large scale (1:2000) inventory of hydrographic mapping of sufficient detail to support hydrology characterization work at a level that accounts for the influences of significant watercourse features, such as tile drains, municipal drains, roads and culverts, which exert a controlling influence on overland and near sub-surface flows. The Contemporary Mapping of Watercourses feature class is developed from hydrologically coded break lines (select point density) from a photogrammetric digital terrain model (2010 and 2013) that collectively provide a detailed representation of the drainage of the landscape. Each surface water segment is imbedded with information characterizing the physical and technical attributes associated with that hydrographic feature aiming to inform water resources management activities. Further, the Contemporary Mapping of Watercourses dataset provides a spatial framework with which to organize, manage and maintain Niagara’s hydrologic data.
