This data set contains the polygons delimiting the wetlands of the Montreal agglomeration. These were updated as part of the development of the [Regional Plan for Humid and Hydric Environments (PRMHH)] (https://montreal.ca/articles/un-plan-pour-proteger-les-milieux-humides-et-hydriques-67104) for the agglomeration of Montreal. They illustrate the wetlands, the type of environment and the conservation choices that have been assigned to them to meet the objectives of the Regional Plan. A visualization of the data is possible on the [interactive map] (https://experience.arcgis.com/experience/87e6da34dc3348a1a5e3f1014c266242) associated with the PRMHH.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Five riparian classes of wetlands (W1 to W5) based on whether the wetland is a simple wetland or wetland complex, wetland size, and biogeoclimatic unit in which the wetland occurs. Wetland classification is based on the 1995 Forest Practices Code Riparian Management Area Guidebook: http://www.llbc.leg.bc.ca/public/PubDocs/bcdocs/237312/Rip-toc.htm

This data set contains the routes of watercourses (stream, river) and main ditches in the agglomeration of Montreal.

Mapping and classifying wetlands and adjacent upland habitat in the Indian River valley, Yukon

The USGS National Hydrography Dataset (NHD) service from The National Map (TNM) is a comprehensive set of digital spatial data that encodes information about naturally occurring and constructed bodies of surface water (lakes, ponds, and reservoirs), paths through which water flows (canals, ditches, streams, and rivers), and related entities such as point features (springs, wells, stream gages, and dams). The information encoded about these features includes classification and other characteristics, delineation, geographic name, position and related measures, a "reach code" through which other information can be related to the NHD, and the direction of water flow. The network of reach codes delineating water and transported material flow allows users to trace movement in upstream and downstream directions. In addition to this geographic information, the dataset contains metadata that supports the exchange of future updates and improvements to the data. The NHD is available nationwide in two seamless datasets, one based on 1:24,000-scale maps and referred to as high resolution NHD, and the other based on 1:100,000-scale maps and referred to as medium resolution NHD. Additional selected areas in the United States are available based on larger scales, such as 1:5,000-scale or greater, and referred to as local resolution NHD. The NHD from The National Map supports many applications, such as making maps, geocoding observations, flow modeling, data maintenance, and stewardship. For additional information on the NHD, go to http://nhd.usgs.gov/index.html. The Watershed Boundary Dataset (WBD) is a companion dataset to the NHD. It defines the perimeter of drainage areas formed by the terrain and other landscape characteristics. The drainage areas are nested within each other so that a large drainage area, such as the Upper Mississippi River, will be composed of multiple smaller drainage areas, such as the Wisconsin River. Each of these smaller areas can further be subdivided into smaller and smaller drainage areas. The WBD uses six different levels in this hierarchy, with the smallest averaging about 30,000 acres. The WBD is made up of polygons nested into six levels of data respectively defined by Regions, Subregions, Basins, Subbasins, Watersheds, and Subwatersheds. For additional information on the WBD, go to http://nhd.usgs.gov/wbd.html. The National Map hydrography data is commonly combined with other data themes, such as boundaries, elevation, structures, and transportation, to produce general reference base maps. The National Map viewer allows free downloads of public domain NHD and WBD data in either Esri File or Personal Geodatabase, or Shapefile formats.
