An extent of land covered by, intermittent and permanent, water bodies and watercourses. This includes both parcel bounding and non-parcel bounding occurrences. Includes the natural watercourses as follows: Bow River Elbow River Nose Creek West Nose Creek Fish Creek. This is a generalized version of the data set and is intended for cartographic purposes and faster drawing time.

These inundation maps show whether a property is at risk for various sized river floods. The size of flood shown on this map has a 1/5 or a 20% chance of occurring in any year.

The three distinct types of inundation shown on the maps are:
o Inundation - Area flooded overland due to riverbank overtopping.
o Isolated - Low lying areas that will not be wet from riverbank overtopping, but may experience groundwater seepage or stormwater backup.
o Potential failure of flood protection barrier - Low lying areas that could be flooded if an existing permanent flood protection barrier were to fail.

The flood areas shown were mapped in 2015 jointly by Alberta Environment and Parks and the City of Calgary, using the best available hydrologic and hydraulic data and models. As such, the flooding shown reflects 2015 conditions, hydrology and topography. The effects of mitigation measures (changes to reservoirs/dams or barriers) built since 2015 are not included. There is uncertainty inherent in predicting the effects of flood events, and this uncertainty increases for floods with less than a 1% chance of occurrence in any year. Any use of this data must recognizing the uncertainty with regards to the exact location and extent of flooding.

The flood extents line was manually delineated from an aerial photo taken on June 22, 2013, and does not represent the peak or maximum flood extents during the June 2013 flood event. This aerial photo was taken somewhat after the flood peak had passed. Actual peak flood extents may have been greater than shown. There may be some error in the extents shown due to the method used for creating the line from the aerial photo (interference of trees, shadows, etc. when interpreting the location of flood water in the photo).
Export as Shapefile or GeoJSON.

The approximate flows at the time the aerial photo was taken:
-Bow River upstream of where the Elbow River joins it: 1575 m3/s at time of aerial photo (1840 m3/s at 2013 flood peak flow)
-Elbow River downstream of Glenmore Dam: 550m3/s at time of aerial photo (700 m3/s at 2013 flood peak flow)
