Drainage basins of Manitoba.Hydrologic drainage basins found within Manitoba. The Assiniboine River basin is divided to indicate the Shellmouth Reservoir subbasin, to better illustrate local impacts and conditions. Basin names are in English and French. 

Province-wide SDE spatial layer displaying the approximate extent and providing the elevation of designated permitted power-storage reservoir areas over crown lands, along with water licence attributes. This layer is an instantiation of the spatial view WLS_RESERVOIR_PMT_LICENSEE_SVW

Radiocarbon dates are derived from organic samples collected through marine and coastal expeditions of the Geological Survey of Canada Atlantic and Pacific. These efforts were conducted primarily to better understand the spatial and temporal coverage of sediments and seabed-fast marine ice during the last deglaciation. The quality of these data varies - ranging from imprecise bulk samples and more accurate AMS estimates derived from single shell fragments. These data are ordered in the menu in 1000 year divisions. By default, only conventional radiocarbon ages are displayed, and reservoir-corrected and measured ages are hidden.

This line and polygon dataset was created to provide a record of the designated Provincial Waterways in Manitoba.This database contains lines and polygons showing the locations of provincial waterways, such as drains, dikes, diversions, detention basins, floodways, dams and reservoirs. This dataset was created by digitizing high-resolution imagery of the water features and by digitizing the titled Water Control Work plans associated with the features for drains which have been designated as provincial waterways by Order-in-Council. This dataset was created to provide a record of the designated Provincial Waterways in Manitoba and was intended for use in administering Provincial Waterways Authorizations. Provincial Waterways are designated by Order-in-Council and are under the administration and control of Manitoba Infrastructure (MI) through the Water Resource Administration Act.

The Standardized Precipitation Index (SPI) has been recognized as the most accessible index for quantifying and reporting meteorological drought. On short timescales, the SPI is closely related to soil moisture, while at longer timescales, the SPI can be related to groundwater and reservoir storage. The model uses observed historical precipitation amounts to compute probability distributions which are then normalized using an incomplete gamma function over a range of timescales. The values can be interpreted as the number of standard deviations by which the observed anomaly deviates from the long-term mean. where positive values (greater than zero) result from above average conditions.

This polygon layer displays sub-basin-level average precipitation derived from the ECMWF (European Centre for Medium-Range Weather Forecasts) model. This layer helps hydrologists, forecasters, and planners see how much rainfall/snowfall is predicted or has occurred in each sub-basin, supporting medium-range water resource and flood management. We are intersested in the forecast period of 7 days.This layer aggregates ECMWF forecast precipitation over polygonal sub-basins. Each feature includes attributes for average accumulated precipitation, forecast run/valid times, and sub-basin identifiers. ECMWF is a leading global model offering medium-range (up to 10 days) forecasts at a high skill level. By focusing on sub-basins, this layer aids in local-scale decision-making—enabling more precise flood risk assessments, reservoir inflow estimates, and water resource planning across the region of interest.

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.

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.
