Alberta Environment and Parks retained NHC in April 2019 to complete a flood hazard study for the City of Camrose and adjacent areas in Camrose County. The study area includes 19 km of Camrose Creek, extending from near the airport to downstream of NW-9-46-20-W4M.

The study is being conducted under the Flood Hazard Identification Program with the intent to enhance public safety and reduce future flood damages within the Province of Alberta. Results from this study are intended to inform local land use planning decisions, flood mitigation projects, and emergency response planning.

The study is comprised of five major project components (Survey and Base Data Collection, Open Water Hydrology Assessment, Open Water Hydraulic Modelling, Open Water Flood Inundation Mapping, and Design Flood Hazard Mapping).

Frequency floods with various return periods were determined through the hydrology assessment. A hydraulic model was created with the survey data and validated to observed floods. The model was used to simulate a total of 13 flood scenarios, and flood inundation maps were subsequently created for the 2-, 5-, 10-, 20-, 35-, 50-, 75-, 100-, 200-, 350-, 500-, 750-, and 1000-year events. Encroachment analysis was performed for the 100-year flood. The results were used to delineate the floodway and flood fringe boundaries and to create floodway criteria/flood hazard maps.
