100 year peak flow isolines in cubic metres per second (m3/s) for 100 square kilometre watersheds and 100 year return period

10 year peak flow isolines in cubic metres per second (m3/s) for 100 square kilometre watersheds and 10 year return period

Groundwater flow is the movement of water in an aquifer or hydrogeological unit. The dataset shows groundwater flow rate and direction in the hydrogeological unit. Groundwater flow is establish from piezometric surface map. The method used to create the dataset is described in the metadata associated with the dataset. The dataset represents a description of the flow, including rate in m/d, direction, date and source. Typically, the data provided will not be in the form of a shapefile with linked properties but in the form of an image that sketches the groundwater flow. The image could also represent a cross section of the hydrogeologic units showing the regional trends of the groundwater flow.

Points with rotations that indicate downstream flow direction. Can be displayed with arrow symbols to show flow direction. There is one point at the upstream end for each stream network feature

Flow network arcs (observed, inferred and constructed). Contains no banks, coast or watershed bourdary arcs. Directionalized and connected. Contains heirarchial key and route identifier

The lightweight web app shows the locations of several river and lake stations where water levels and/or flow data are collected in Manitoba.The web map shows the locations of several river and lake stations where water levels and/or flow data are collected. When you click on a location on this map, a pop-up box will appear.  The pop-up box contains various water level and/or flow data, as well as forecast information. Please note these conditions regarding the information contained in the pop-up boxes:The information on this map is updated daily at 1:00 pm during the spring runoff period, based on water levels and flows collected earlier in the morning.  The water levels and flows should be considered preliminary data as they could be affected by ice, wind, or monitoring equipment malfunctions. While the department undertakes due diligence in utilizing this data, final quality control checked data is published by Water Survey of Canada, our main data provider, after the spring runoff.  Forecasted peak information is the most recent data available. Forecasts are evaluated daily and any updates are included in the Daily Flood Sheets and the Flood Report; both of these are available on the Manitoba Flood Forecast website. If the updated forecasts will not be available until later in the afternoon, the forecasted peak information in the pop-up boxes will be from yesterday’s Daily Flood Sheets.Pop-up boxes include the following information: Station Name: station name where the water level and/or flow data are collected Station ID: unique identifier for the station Flood Alert: indicates if the current water level is over the flood stage, over the river bank but below the flood stage, or below the river bank.  Last Update: date that water level and/or flow data was collected  Flow: measured or calculated flow in cubic feet per second  Level: measured water level in feet  Forecasted Flow: the forecasted peak flow in cubic feet per second Forecasted Level: the water level at the forecasted peak in feet Peak Date: date when the peak is forecasted to occur Flood Stage (dike level) (ft): the water level (ft) at which flow overtops community flood protection dike-structures Bankfull Capacity - flow (cfs): the approximate flow (in cubic feet per second) when the water level is at the top of the bank  Bankfull Capacity - level (ft): the water level (in feet)  when the water is at the top of the bank Reference Years:  years when the peak water levels were similar to the forecasted peak water level this year“Flood Alert” definitions:  Flood Warning: A flood warning is issued when water levels are above or expected to be above channel capacity within the next 24 hours, resulting in minor to major flooding. Water is beyond the channel capacity and expected to flood adjacent areas, agricultural fields and/or infrastructure in the area.  High Water Advisory / Flood Watch: A high water advisory is issued when water levels are above seasonal levels. A High Water Advisory can be an early indicator for conditions that may develop into a Flood Watch. A flood watch is issued when water levels are nearing channel capacity, but not expected to reach channel capacity within the next 24 hours. Minor to no flooding is expected at these levels, but water may begin to overflow into nearby low-lying marshland, parkland or floodplain areas with little to no impact. A Flood Watch can be an early indicator for conditions that may develop into a Flood Warning.   Above Community Flood Protection Level: Water levels are above or projected to be above the community dike levels within 24 hours, causing major flooding.

The North America Surface Water Values point dataset contains the current water level and stream flow values as recorded by Canadian and USA hydrometric gauging station locations. Daily values are recorded as well as comparisons with historical measurements, including difference in values from the previous day, the mean level for that calendar date, the annual mean water level, and maximum and minumum recorded levels. Percentile values based on historical average for both water level and stream flow are also included.Real-time gauging station data for Canada is available here: https://wateroffice.ec.gc.ca/search/statistics_e.htmlReal-time gauging station data for the United States is available here: https://waterservices.usgs.gov/rest/Statistics-Service.html

The daily mean is the average of all unit values for a given day.

Hydro Features is composed of the network of Canadian surface waters. Hydro Features entities are: Watercourse, Water Linear Flow, Hydro Obstacle (falls, rapids\...), Waterbody (lake, watercourse\...), Permanent Snow and Ice, Water Well, and Spring. CanVec is a digital cartographic reference product of Natural Resources Canada (NRCan). It originates from the best available data sources covering Canadian territory, offers quality topographical information in vector format, and complies with international geomatics standards. CanVec is a multi-source product coming mainly from the National Topographic Data Base (NTDB), the Mapping the North process conducted by the Canada Center for Mapping and Earth Observation (CCMEO), the Atlas of Canada data, the GeoBase initiative, and the data update using satellite imagery coverage (e.g. Landsat 7, Spot, Radarsat, etc.).Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .
