Situated in the Gwich’in settlement Area (GSA), the Rat River is inhabited by anadromous Dolly Varden (Salvelinus malma malma) that are harvested by both Gwich’in and Inuvialuit beneficiaries. The harvest of Dolly Varden from the Rat River occurs during the summer at feeding areas along the coast (by the Inuvialuit) and during upstream migration in the Mackenzie Delta (by both Gwich’in and Inuvialuit). Dolly Varden stocks are co-managed under an Integrated Fisheries Management Plan (IFMP) whose signatories include Fisheries and Oceans Canada (DFO), Gwich'in Renewable Resources Board, Fisheries Joint Management Committee, and Parks Canada Agency. The Rat River Working Group, the co-management body that makes recommendations for harvest levels for Dolly Varden stocks in the GSA, has supported research activities that facilitate implementation of the IFMP, including studies to monitor harvest levels and assess population status. Population studies (e.g., abundance estimates, biological and genetic sampling) and coastal harvest monitoring activities allow for a comprehensive assessment of this stock. The data are used to inform co-management partners on the status of Dolly Varden from the Rat River.

The Inuit Regions, also known as the Inuit Nunangat, dataset contains the geographical boundaries of the 4 Inuit Regions in Canada: Inuvialuit, Nunavut, Nunavik and Nunatsiavut. The boundaries, land only, have been drawn as per information defined in each land claim agreement. The Inuit Regions (Inuit Nunangat) geographical boundaries are approximate and should be used for illustration purposes only.This dataset is Crown-Indigenous Relations and Northern Affairs Canada (CIRNAC) and Indigenous Services Canada (ISC) official source for Inuit regions on maps.

For the purpose of this dataset, an Indigenous government or group refers to both elected Indigenous governments, and entities that are formally designated to represent individual Indigenous rights-holders but does not include Indigenous advocacy organizations such as the Assembly of First Nations, the Council of Yukon First Nations or boards, committees or councils established to represent community interests.For the purpose of this data set, Indigenous governments can include but is not limited to a Yukon First Nation or a transboundary Indigenous government. A “Yukon First Nation” refers to a First Nation that is included in the definition of “Yukon First Nation” in the Umbrella Final Agreement, and includes: Carcross/Tagish First Nation, Champagne and Aishihik First Nations, Kluane First Nation, Kwanlin Dün First Nation, Liard First Nation (Kaska Nation), Little Salmon/Carmacks First Nation, First Nation of Nacho Nyak Dun, Ross River Dena Council (Kaska Nation), Selkirk First Nation, Ta’an Kwach’an Council, Teslin Tlingit Council, Tr’ondëk Hwëch’in (identified in the Umbrella Final Agreement as “Dawson First Nation”), Vuntut Gwitchin First Nation, and White River First Nation.A transboundary Indigenous government refers to an Indigenous government that is based outside of the Yukon, and includes: Acho Dene Koe First Nation, Dease River First Nation (Kaska Nation), Kwadacha Nation (Kaska Nation), Gwich’in Tribal Council, Tetlit Gwich’in Council, Inuvialuit Regional Corporation, Inuvialuit Game Council, Tahltan Central Government, Taku River Tlingit First Nation, and Pehdzeh Ki First Nation.For this dataset, a boundary is a depiction of a division between different geographic regions associated with an Indigenous government (e.g., a full or partial periphery of a “traditional territory”). A boundary can include, but is not limited to, a “traditional territory” or “Traditional Territory”. For this dataset, a traditional territory or Traditional Territory is a geographic area where a group of Indigenous Peoples holds or asserts Indigenous rights, and which may be established by a treaty or confirmed in a court ruling.The term “Traditional Territory” (capitalized) is defined in the Umbrella Final Agreement and specifically refers to the territories identified in the maps submitted by each Yukon First Nation during the negotiation of that agreement and each Yukon First Nation final agreement. Some Indigenous governments and groups or the text of their treaty agreements do not use the term “traditional territory”. For example, the Gwich’in Tribal Council’s boundary in Yukon is more accurately described as Tetlit Gwich'in Yukon Lands and the Inuvialuit Regional Corporation’s boundary in Yukon is more accurately described as the Inuvialuit Settlement Region. Historical use and occupancy information can be used to understand assertions of rights within a traditional territory that has not been formally established.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.

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.

A hydrogeological unit is defined as any soil or rock unit or zone that by virtue of its hydraulic properties has a distinct influence on the storage or movement of groundwater. It is considered the main dataset from the GGP point of view. Hydrogeological units are ranked into five levels (from largest to smallest): 1) hydrogeological region, 2) hydrogeological context, 3) aquifer system, 4) hydrostratigraphic unit, and 5) aquifer. Here are formal definitions for these different types of hydrogeologic units. - Hydrogeological region Hydrogeological regions are areas in which the properties of sub-surface water, or groundwater, are broadly similar in geology, climate and topography. There are 9 such regions identified in Canada (ref?). - Hydrogeological context Hydrogeological contexts are units of reporting, conceptually narrower than regions, and are additionally delineated by physiographic and hydrogeological aspects. - Aquifer system ""A heterogeneous body of intercalated permeable and poorly permeable material that functions regionally as a water-yielding hydraulic unit; it comprises two or more permeable beds [aquifers] separated at least locally by aquitards [confining units] that impede groundwater movement but do not greatly affect the regional hydraulic continuity of the system"" (Poland et al., 1972). - Hydrostratigraphic unit (HSU) ""Body of sediment and/or rock characterized by ground water flow that can be demonstrated to be distinct under both unstressed (natural) and stressed (pumping) conditions, and is distinguishable from flow in other HSUs"" (Noyes et al.) - Aquifer ""A formation, group of formations, or part of a formation that contains sufficient saturated permeable material to yield significant quantities of water to wells and springs"" (Lohman et al, 1972, p. 21). The rank attribute is used to specify the scope of the described unit. The general principle behind this specification is to allow the same data structure to apply to various types of hydrogeological units, from the local aquifer to the almost continental hydrogeological region. The dataset includes properties such as identification, physiography, geology, aquifer description and properties, water balance, groundwater use and risk. It features numerical values or a general description when no values are available. The description can also be used to add context to the numerical values. For each property, metadata identifying the source of the original data, links to similar data in GIN, and description of the processes, algorithms or methodology used to obtain these datasets will be available to complement the data. This dataset is designed to capture and represent a set of synthesized information pertaining to hydrogeological units through maps and succinct table reports. Some attributes (or properties) of the dataset are irrelevant depending of the rank of the unit. In general, this dataset is organised to include multiple properties associated with aquifers and larger hydrogeologic units. These properties are grouped into categories, which include identification, physiography, geology, aquifer description, water balance, groundwater use and risk. The numerical values associated with each of the properties can be used to create thematic maps; hence, the importance of using standardized units of measurement and definitions for these properties. When numerical values are not available, a general description may be supplied instead. The description can also be used to add context to the numerical values. Because this dataset is the cornerstone of the national view on groundwater, supplemental contextual information (metadata) must be part of the data. Thus, for each property, metadata identifying the source of the original data, links to similar data in GIN, and a description of the processes, algorithms or methodology used to obtain these datasets will be available to complement the data.
