Point features showing the locations of groundwater wells with pumping test information and/or aquifer parameter data. Some wells may have more than one pumping test record. Further context regarding the pumping tests and analysis are provided with the well records in GWELLS (https://apps.nrs.gov.bc.ca/gwells/).

Point features showing the locations of groundwater wells which have lithology recorded. Each record in the dataset represents a lithology interval. Because each water well often has multiple lithology layers recorded, there will often be multiple points overlapped at each well location. For the locations of all water wells in BC (without lithology), please see: https://catalogue.data.gov.bc.ca/dataset/e4731a85-ffca-4112-8caf-cb0a96905778 > NOTE: When choosing to download this GIS dataset below, there can be errors when trying to download the entire province. The large file size is a problem for the default file format (shapefile). > If you need to download the entire province, please choose a different file format (e.g. ESRI File Geodatabase). > If you need to download in shapefile format, please use an area of interest (AOI).

Point features showing the location of intakes and/or wellheads for drinking water systems. A drinking water system is any domestic system servicing anything other than a single-family dwelling, as defined in the Drinking Water Protection Act. These locations are updated as more information is received and is therefore continually being updated and may or may not match the corresponding Point of Diversion locations available through the Water Rights dataset and application. This is one of three Drinking Water Sources datasets (along with the DWS - Source Areas polygons dataset, and DWS - Protection Zones polygons dataset). Note: the polygons all have unique polygon IDs used to relate them to these points.

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 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.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

This theme presents the index of water health along the banks of the St. Lawrence River. It makes it possible to determine if the sites present risks to human health and if they are suitable for swimming.These data are the result of an exploratory monitoring program that aims to raise awareness among the population and local actors about the possible reopening of bathing sites that have good potential. This program also makes it possible to highlight any improvement in bacteriological quality resulting from the reduction of wastewater overflows during rainy weather or resulting from the installation of disinfection equipment.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The Drainage Areas dataset is largely based on the Water Survey of Canada (WSC) drainage area boundaries at the sub-sub-basin level. The data model supports the derivation, from the Fundamental Drainage Areas dataset (sub-sub-basin level), of the WSC and Atlas of Canada drainage area hierarchies and the data is available in all three schemes. Drainage area definitions for both WSC and Atlas of Canada boundaries were reviewed resulting in some modifications. Larger scale reference data sources were used for further manual boundary adjustments. This dataset has been integrated with other National Scale Frameworks hydrology datasets and is considered a component of the Hydrology Theme (see Supplemental Information for more details about the Atlas of Canada National Frameworks data at the 1:1,000,000 scale).The Atlas Frameworks are a set of integrated base map layers which form part of a larger National-Scale Frameworks data collection.

Assessment Watersheds are mesoscale aquatic units designed to replace the 3rd order 1:50K watersheds. Assessment Watersheds are based on groupings of fundamental watersheds using FWA watershed code and local code, with a target size of between 2,000ha and 10,000ha.

Well capture zones are intended to identify potential areas of risk to aquifers where the release of contaminants could affect the water quality of community wells. The information was compiled as a discreet project under the 'Yukon Water Strategy' and represents a 'snapshot in time' of the Drinking Water Systems. Well capture zones were identified using a combination of buffers, analytical methods, and groundwater flow modelling using the Waterloo Hydrogeologic Inc. Visual MODFLOW.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Groundwater samples have been collected in the hydrogeological unit, for various types of analysis. The dataset is not used to represent a particular phenomenon or observation but rather as a utility dataset to add context and reference to groundwater analysis. It represents a general description of the sample site and sample. Sampling methods vary according to the types of analysis.

This theme includes the drainage areas of various watercourse monitoring stations (physicochemical and bacteriological, benthic organisms, diatoms, pesticides, etc.) carried out by the Ministry of the Environment, the Fight against Climate Change, Wildlife and Parks (MELCCFP) as well as lake catchments (MELCCFP) as well as lake catchments including the majority of lakes in the Voluntary Lake Monitoring Network (RSVL).The drainage area and the watershed represent the territory whose water flows to the sampling station or to the outlet of the lake. Boundaries are generated using a geographic information system (GIS) from topographic maps, numerical elevation models and flow models, and watershed boundaries produced by the Main Directorate of Water Expertise (DPEH).The drainage area and watershed are used to calculate the area drained upstream of the sampling station or lake, to characterize the drained territory (for example, to determine land use), and to meet specific mapping needs. The linked tables also provide compilations of land use according to three classifications to contextualize the various monitoring carried out at the stations. Note that the use of land outside Quebec, drainage areas and transboundary watersheds is not calculated and that the percentages in each category correspond to the Quebec area only.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
