The dataset contains data for placer watersheds locations. The dataset covers 18 watersheds within the Yukon Territory. The following watersheds form the principle boundaries of the dataset: Big Creek, Big Salmon River, Forty Mile River Indian River, Klondike River, Mayo River McQuesten River, Nisutlin River, Nordenskiold River Pelly River, Sixty Mile River, Southern Lakes (Yukon) Stewart River, White River*, Yukon River North Yukon River South, Alsek River, Liard River *Note - A small portion of the headwaters of the Tanana River (Yukon) watershed is associated within the boundaries of the White River watershed .

A placer claim is a parcel of land located or granted for placer mining. A claim also includes any ditches or water rights used for mining the claim and all other things belonging to or used in the working of the claim for mining purposes. A placer claim is a rectangular plot of ground. All angles of a claim must be right angles, except in the cases where a boundary line of a previously located claim is adopted as common to both locations. The length of a regular placer claim from post one to post two is 500 feet along a baseline. Co-discovery claims must not exceed 1250 feet each and single discovery claims must not exceed 1500 feet. The Placer Mining Act is available at http://www.gov.yk.ca/legislation/acts/plmi.pdf Visit http://www.emr.gov.yk.ca/mining/placermining.html for detail on how to stake, record and maintain a Placer Claim.

The dataset contains data for watercourses (locations), watercourse gradient (based on elevation), water quality (total suspended solids), currently known Chinook and chum salmon spawning areas, areas of special consideration (fisheries or fish utilization by man) and previous placer mining development. The dataset covers 18 watersheds within the Yukon Territory and employs a single-line hydraulic network to connect all identified NTDB watercourse reaches. Spatial data for watercourses, gradient (based on elevation), water quality (total suspended solids), currently known Chinook and chum salmon spawning areas and previous placer mining development have been corrected to produce an integrated, topologically connected dataset. The dataset contains approximately 1,153,179 reach segments and over 80,000 water bodies. The dataset is used by a predictive analysis model in order to identify a /score/ for individual stream reaches and watersheds that ultimately identifies fish habitat suitability based on the key environmental indicators. The dataset extent is limited within 18 watershed boundaries in the Yukon Territory. Minor overlap exists outside of Yukon geopolitical boundaries in order to maintain hydraulic networks for watersheds that flow from or through Alaska and British Columbia. The following watersheds form the principle boundaries of the dataset: Big Creek, Big Salmon River, Forty Mile River Indian River, Klondike River, Mayo River McQuesten River, Nisutlin River, Nordenskiold River Pelly River, Sixty Mile River, Southern Lakes (Yukon) Stewart River, White River*, Yukon River North Yukon River South, Alsek River, Liard River *Note - A small portion of the headwaters of the Tanana River (Yukon) watershed is associated within the boundaries of the White River watershed.

The Adaptive Management Framework for Yukon placer mining is complemented by traditional knowledge and monitoring of water quality objectives, aquatic health, and economic health.The aquatic Health monitoring program is governed by the Aquatic Health Monitoring Protocol.The Protocol describes the locations, timing, frequency and methods employed duringsampling, as well as the methods used to analyze sampling data. The Reference ConditionApproach (RCA) is the method chosen for assessing the health of freshwater ecosystems inthe Yukon. One RCA model was developed for bioassessment based upon benthicmacroinvertebrates, and a second model was developed to assess the diversity of fishspecies.The RCA model for invertebrates relies upon 224 reference sites collected over the period 2004 to 2010 by the University of Western Ontario, Fisheries and Oceans Canada, and theYukon government, using the same standard protocol. The invertebrate data set was analyzedat the family level.There are two fundamental steps in the process of developing the predictive model. The first isto classify the reference sites based on their biological characteristics. This requires defining anumber of community types based on the taxonomic composition. The second step is todetermine a subset of habitat attributes that are associated with those community types.Following this step the number and type of organisms expected to occur at any given site canbe determined from habitat attributes.For more information, contact the Yukon Placer Secretariat

The Yukon government amended the Quartz Mining Act and the Placer Mining Actin December 2013, to establish the authority to designate areas where government notification of Class 1 exploration activities is required.Before these amendments to the mining acts and regulation came into effect, prospectors undertaking Class 1 activities were not required to inform government of their work. Class 1 exploration activities generally have low potential to cause adverse environmental effects.A Notification is required if an exploration program is categorized as class 1 (OIC 2003/59 and OIC 2003/64) and located either on settlement land (category A or B) or within a class 1 notification area (OIC 2013/221). This layer show current class 1 exploration program that are allowed to proceed.

A placer claim is a parcel of land located or granted for placer mining. A claim also includes any ditches or water rights used for mining the claim and all other things belonging to or used in the working of the claim for mining purposes. A placer claim is a rectangular plot of ground.

The grid system used in Mineral Titles Online (MTO). This grid is used to determine the location of mineral and placer cell titles in B.C. The grid is designed based on the Mineral Title Online Grid Regulation. The mineral-placer grid does not show current cell availability status. The dataset is very large and cannot be downloaded for the entire province. Try selecting specific mapsheet grids or selecting by an area of interest to download in sections.
