Flood extent polygons from the current calendar year in selected Canadian regions that have been designated for observation, monitored by Natural Resources Canada using satellite imagery for emergency response. Coverage is not comprehensive nationwide. In response to large flood events, Natural Resources Canada (NRCan), for the provision of emergency geomatics services, may be activated by Canada’s emergency management protocols. As new satellite imagery becomes available, NRCan will extract flood extent polygons and update the dataset in near real time (4 hours). This item contains the flood products generated in the past year. For any data relating to previous years, please refer to the [Floods in Canada – Archive]( https://open.canada.ca/data/en/dataset/74144824-206e-4cea-9fb9-72925a128189) entry. Please note that the web mapping service may not display data if flood polygons have not been published by the EGS for the current year. The flood products generated are validated on a best effort basis. Various factors may affect the quality of the flood polygons. These factors include, but are not limited to, sensor type, image resolution, cloud cover or limitations of the flood polygon extraction method. In this layer, where possible, a symbology is applied to the flood polygons based on the underlying land use classification, or is simply unclassified and shows the raw flood extent. When using Web mapping services, to display a specific product, filter by date (UTC Date) and area of interest (AOI). Also, a link to download each product is available in the Resources section. This prepackaged and compressed product contains a Shape file, a PDF file and a KMZ file. Disclaimer : Emergency response authorities are the primary users of these satellite-derived open water flood extent map products. These products are generated to provide analysis and emergency response situational awareness and to facilitate decision-making during major flood events. The open water flood extent products are generated rapidly and limited time is available for editing and validation. The flood products reflect the open water flood conditions at the date/time of acquisition. While efforts are made to produce high quality products, near-real time products may contain errors due to the limited time available for vector editing and validation.

Representation of the causes of flooding events in the form of multiple points. The point groupings correspond to the set of locations that were affected by the same event. The inventory of past flooding events was compiled from various public sources and standardized into a common data model. Sources used are included in the data. Event locations have been extensively revised to have one location per location reported as affected by the flood. Flood events for which no location was included in the sources used are positioned on the place name of the location affected by the flood. The event positions do not indicate where the flooding occurred. Flood events that affected more than one locality are represented by a multipoint.For each event after January 1, 1980 caused by a heavy rainfall or a coastal storm , a precipitation analysis document, a precipitation animation and the precipitation data are available. These documents are the result of a collaboration with Environment and Climate Change Canada.Disclaimer:It should be noted that no consultation was conducted with the various providers and stakeholders of the historic flood data. Disparities in content among the various sources result in an incomlete product. No warranty is given as to the accuracy or completeness of the information provided. The absence of information does not mean that no flooding has occurred.

This database aggregates basic information on orphaned and abandoned mine sites from participating Canadian jurisdictions, including their name, location, jurisdiciton, and the commodity that was mined. It was originally created in 2012 through the National Orphaned/Abandoned Mines Initiative and has undergone several updates since that time. Data on sites in each jurisdiction is owned and maintained by that jurisdiction. The database includes links to the corresponding records in that jursidiction. While the database includes common informaiton about all sites, there may be discrepancies in the types of data provided about sites in different jurisdictions and data from some jurisdictions may be updated more frequently than others.

The [Southern Lakes flood hazard mapping study](https://flood-atlas.service.yukon.ca/pages/final-flood-maps) was completed between November 2022 and April 2024. Learn more by visiting the [Yukon Flood Atlas](https://flood-atlas.service.yukon.ca/pages/final-flood-maps).In the Resources section below, you can find the project summary, technical report, "What We Heard" report, GIS data files, and flood maps for specific areas."AEP" in the flood map filenames below refers to "Annual Exceedance Probability", the annual likelihood of a flood occurring, expressed as a percentage.The flood scenarios used for mapping in the Yukon are the following:- 0.5% event (1-in-200 chance of occurring in any year),- 1% event (1-in-100 chance of occurring in any year), and- 5% event (1-in-20 chance of occurring in any year).For more information see [What is flood mapping?](https://flood-atlas.service.yukon.ca/pages/flood-mapping) or email [FloodMapping@yukon.ca](mailto:floodmapping@yukon.ca).### See also- [Carmacks flood hazard maps](https://open.yukon.ca/data/datasets/carmacks-flood-hazard-maps)- [Teslin flood hazard maps](https://open.yukon.ca/data/datasets/teslin-flood-hazard-maps)

This national map of flood susceptibility or flood prone areas is based on patterns of historic flood events as predicted by an ensemble machine learning model.The recommended use is national, provincial or regional scale and can be used as a guide for identifying areas for further investigation. The Flood Susceptibility Index (FSI) Dataset, while processed and available at 30m cell size, is not recommended for use at the pixel or street level, given the uncertainty in the modelling process and the variability of results as discussed in https://www.mdpi.com/2673-4931/25/1/18 .For additional details on the methods, tests, models and datasets used to generate this data layer, please see https://geoscan.nrcan.gc.ca/starweb/geoscan/servlet.starweb?path=geoscan/fulle.web&search1=R=329493

The Ministry of Public Security (MSP) supports the development of knowledge of flood risks. In collaboration with Laval University and the Reunification of Quebec Basin Organizations, the MSP has developed a methodical and rigorous process for documenting floods that have an impact on the safety of people and essential goods.Thus, since 2017, the Ministry of Public Security (MSP) has been acquiring in certain cases data related to the water level reached when floods with proven consequences occur in southern Quebec. Maximum water levels are indicated by flood overflows.__What is a flood wasteland? __A flood (flood) is characterized by a rise in water on land that is usually dry, the reaching of a peak, then a descent of water (decline). Waste forms at the beginning of the flood when the water, when withdrawing, deposits materials that were in suspension or floating. These materials (mud, seeds, twigs and other debris) constitute flood wastes or flood plains.__Marking and surveying flood plains and water levels__The marking of floodplains and water levels takes place on the ground shortly after the peak of the flood. The physical indices of the maximum water level reached (abandoned by the flood) or of the current water levels are identified and marked using permanent markers (markers). Afterwards, a land surveyor will precisely record the location and the altitude of the markers. __Point dataset “Water levels during a flood"__The “Water levels during a flood” data set contains, for each marker, the date, altitude and location (measured by a land surveyor). There are two main types of observations made in the field: the natural flood defect (line of mud, seeds or trace of water) which indicates the maximum water level reached during the flood (called MAX) and the water level observed during the field visit (called CURRENT). The list of all attributes is provided in the dataset description sheet (Additional Information section).Despite the quality of the work carried out, the Ministry of Public Security cannot guarantee the absence of errors in the data.__Related datasets__ The “Flood markers” dataset produced by the Ministry of Public Security also contains maximum water levels reached during a flood. The link to this dataset is provided in the _Documentation_ section.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
