The hydrographic features of the CanVec series include watercourses, water linear flow segments, hydrographic obstacles (falls, rapids, etc.), waterbodies (lakes, watercourses, etc.), permanent snow and ice features, water wells and springs. The Hydrographic features theme provides quality vector geospatial data (current, accurate, and consistent) of Canadian hydrographic phenomena. It aims to offer a geometric description and a set of basic attributes on hydrographic features that comply with international geomatics standards, seamlessly across Canada. The CanVec multiscale series is available as prepackaged downloadable files and by user-defined extent via a Geospatial data extraction tool.

Water files are provided for the mapping of inland and coastal waters, Great Lakes and the St. Lawrence River. These files were created to be used in conjunction with the boundary files.

Atlas of Canada National Frameworks data are standardized national coverages of commonly used geospatial datasets at the 1:1 000 000 scale. The Drainage Network Skeleton dataset is comprised of linear features: single line rivers, flow lines within waterbodies and ocean coastlines. Flow lines within waterbodies are virtual linear features representing the hydrological flow through area features (e.g. lakes, rivers and intermittent waterbodies). These flow lines complete the linear network where rivers would run through lakes, permitting hydrologic network analysis and cartographic generalization. This dataset is required for analytical applications. The coastline component of the Drainage Network Skeleton also delineates oceanic islands. The National Scale Frameworks Hydrology data consists of area, linear and point geospatial and attribute data for Canada's hydrology at a national scale. It provides a representation of Canada's surface water features, and data completeness reflects the content of the source, the original Vector Map level 0 (VMAP0) revision 4 hydrographic layers, except where revision editing has been performed. Key value-added characteristics include river flow direction, connectivity and the tagging of geographical name keys to selected rivers, lakes and islands included in the Concise Gazetteer of Canada. The Atlas Frameworks are a set of integrated base map layers which form part of a larger National Scale Frameworks data collection. These data have been compiled at a scale of 1:1 000 000 with the primary goal being to indicate correct relative positioning with other framework layers rather than absolute positional accuracy.

Hydrology files from DMTI Spatial Inc. CanMap Content Suite for 2018 (water bodies, water lines) were downloaded via the University of Victoria library, and loaded into a PostGRES database. Specifically for distance to oceans, we used the 2011 Hydrographic Layers - coast GIS file from Statistics Canada. Distances in metres to the nearest water feature within 5 kilometres by class (defined below) was calculated using PostGRES, for all DMTI Spatial Inc. single-link postal code for all years. This assumes that water features have remained constant over time. Note: many waterbodies in Alberta were coded as unknown in the water_defn column. Any features that were otherwise coded as permanent and had a river name or lake name were re-coded as watercourse and lake respectively and added to the appropriate class prior to calculation. NOTE: Features from the DMTI waterbody file are large enough to be representing as polygons or rivers/channels with right and left banks delineated. Features from the DMTI waterline file are narrow enough that they are only represented as a single line feature, rather than having a right and left bank.

The Waterbodies dataset is comprised of area features: lakes, intermittent waterbodies, islands, and rivers wide enough to be represented as an area feature (e.g. St. Lawrence River, Mackenzie River). In a few exceptional cases, islands had to be represented by "holes" in the polygons in the Waterbodies dataset. Some area features have been subdivided and several types of virtual linear features serve to separate them. Features in this dataset are linked (by an attribute) to their corresponding flow line in the Drainage Network Skeleton. Therefore the Waterbodies dataset may be used in conjunction with the Drainage Network Skeleton for analytical applications. The Islands dataset is comprised of area and linear features: islands within inland waters and the waterbodies and single line rivers within these islands. Oceanic islands are not included as they are part of the coastline component of the Drainage Network Skeleton dataset. The Islands dataset exists to complete the cartographic representation of Canadian hydrology. The Islands dataset is not logically connected with the Drainage Network Skeleton, and can not be used for analytical applications. It should be noted that flow lines of the Drainage Network Skeleton do not take into account of the existence of islands and therefore do not necessarily flow around them. In a few exceptional cases, islands had to be represented by "holes" in the polygons in the Waterbodies dataset. Some islands themselves contain waterbodies and rivers, not significant for network analysis. However, in order to support a complete cartographic representation such waterbodies and rivers have been added to the Islands dataset.

The Canadian Hydrospatial Network (CHN) is an analysis-ready geospatial network of features that help enable the modelling of surface water flow in Canada. The six main layers and feature types are: flowlines, waterbodies, catchments, catchment aggregates, work units, and hydro nodes. Where possible the CHN is derived from high resolution source data such as Light Detection and Ranging (LiDAR) derived Digital Elevation Models (DEMs) and aerial imagery, to name a few. If existing provincial or territorial hydrographic networks meet the standards, they are incorporated into the CHN, otherwise automatic extraction methods are used on the high-resolution source data. To provide full network connectivity, if neither of these methods is possible in a region, the NHN is converted into the CHN until higher-resolution source data is available. Additional value-added attributes are included in the CHN to aid modelling, such as stream order and reach slope. The CHN physical model and features are also closely aligned and harmonized with the USGS 3DHP hydrographic network, which aids trans-border modelling. Where possible geonames (i.e. toponyms) are also added. The CHN is produced and disseminated by hydrologically connected geographic areas called work units. Work units can contain just one watershed, several small adjacent watersheds outletting into a large body of water, or be one of many parts of a larger watershed. In all cases, the features of a work unit are hydrologically connected. This is a more natural approach to data delivery, in comparison to data that is split into tiles. A generalized work unit index file is provided in the downloads to help users decide which files to download. For more information on the CHN please visit the project webpage: https://natural-resources.canada.ca/canadian-hydrospatial-network

This year-round limnology dataset is from four dimictic Canadian water bodies: three mesotrophic reservoirs in southern Saskatchewan (SK; Blackstrap, Broderick, Diefenbaker) and one oligo-mesotrophic large lake in southern Ontario (Lake Simcoe). Physical, chemical, and biological parameters were measured during the open-water and ice-covered seasons in 2010–2011 (Lake Simcoe) and the SK reservoirs in 2013–2014. Two stations were sampled on Blackstrap reservoir, one on Broderick reservoir, three on Diefenbaker reservoir, and seventeen on Lake Simcoe. Sampling was conducted from a boat during the open-water season and during winter, we accessed the same stations by snowmobile and sampled through holes in the ice. Epilimnetic or surface water was collected for parameters listed below, and δ18O-O2 (oxygen) stable isotope samples were collected from one to 4 depths per station, depending on water column depth and lake thermal structure that day. Parameters reported included photosynthetically active radiation, vertical attenuation coefficient, mean daily mixed layer irradiance, total phosphorus, total dissolved phosphorus, dissolved reactive phosphorus, total dissolved nitrogen, particulate nitrogen, ammonium, nitrate, chlorophyll a, particulate organic carbon, and phytoplankton biovolumes. Photosynthesis irradiance (P-E) parameters were measured including the light saturation parameter, maximum relative electron transport rate through PSII, and the light limited slope of the P-E curve. We also measured areal net productivity, areal gross productivity, and areal respiration via three different methods including fluorometry via a Water-PAM fluorometer, O2 concentrations and δ18O-O2 values, and light-dark bottle experiments measuring changes in O2 concentrations.

The stocking dashboard provides interactive access to Manitoba waterbody information. Filters can be combined to narrow down the waterbodies by: fishing division, waterbody name, fish species, and year stocked. The stocking dashboard is an interface that allows for interactively accessing fish stocking information. It allows filtering and searching for information about stocked lakes. Filters are based on the year of stocking, the fish species stocked, and the fishing division in which the stocking took place. All of these filtering abilities can be compounded to allow users to more effectively find and display information that they are interested in. The dashboard uses the stocking map as its primary tool for users which provides a visual of the filtering options applied. Widgets allow for resetting data to home state view, legend for onscreen features, layers to toggle on and off and ability to change base map options. Additionally there are statistics displayed for total fish stocked, fish stocked in past five years, and fish stocked in the years selected. The latter two statistics are dynamic and update depending on the filters used. This dashboard, along with related information, can be found in the Manitoba Lake Information for Anglers application, an interactive tool for anglers to access waterbody information. The project was initiated by Manitoba Wildlife and Fisheries Branch with funding from the Fish and Wildlife Enhancement Fund. Data is provided by Manitoba Wildlife and Fisheries Branch, Swan Valley Sport Fishing and Manitoba Watershed Districts. For additional information visit Manitoba Fisheries.

This layer is the current fire year burn severity classification for large fires (greater than 100 ha). Burn severity mapping is conducted using best available pre- and post-fire satellite multispectral imagery acquired by the MultiSpectral Instrument (MSI) aboard the Sentinel-2 satellite or the Operational Land Imager (OLI) sensor aboard the Landsat-8 and 9 satellites. Every attempt is made to use cloud, smoke, shadow and snow-free imagery that was acquired prior to September 30th. However, in late fire seasons imagery acquired after September 30th may be used. This layer is considered an interim product for the 1-year-later burn severity dataset (WHSE_FOREST_VEGETATION.VEG_BURN_SEVERITY_SP). Mapping conducted during the following growing season benefits from greater post-fire image availability and is expected to be more representative of tree mortality. #### Methodology: • Select suitable pre- and post-fire imagery or create a cloud/snow/smoke-free composite from multiple images scenes • Calculate normalized burn severity ratio (NBR) for pre- and post-fire images • Calculate difference NBR (dNBR) where dNBR = pre NBR – post NBR • Apply a scaling equation (dNBR_scaled = dNBR*1000 + 275)/5) • Apply BARC thresholds (76, 110, 187) to create a 4-class image (unburned, low severity, medium severity, and high severity) • Mask out water bodies using a satellite-derived water layer • Apply region-based filters to reduce noise • Confirm burn severity analysis results through visual quality control • Produce a vector dataset and apply Euclidian distance smoothing

The Provincial Obstacles to Fish Passage theme presents records of all known obstacles to fish passage from several fisheries datasets. Records from the following datasets have been included: The Fisheries Information Summary System (FISS); the Fish Habitat Inventory and Information Program (FHIIP); the Field Data Information System (FDIS) and the Resource Analysis Branch (RAB) inventory studies. The main intent of this layer is to have a single layer of all known obstacles to fish passage. It is important to note that not all waterbodies have been studied and, not all lengths of many waterbodies have been studied so there are a very high number of obstacles in the real world that are not recorded in this dataset. This layer simply reports the obstacles to fish that are known. It is also very important to note that we are acknowledging these features as obstacles to fish passage versus barriers to fish passage. This is because an obstacle may be a barrier at one time of year but not at other times depending on the volume of water present and also, what is a barrier to one species of fish is not necessarily a barrier to another species.
