Lower Mainland Flood Maps

A Lower Fraser River 2D Flood Modelling and Mapping Project was completed in late 2019 as an important component of the Lower Mainland Flood Management Strategy. The flood model estimated the extents and depths of flooding from a range of flood scenarios to support regional planning. 

Fraser River freshet flood maps in PDF are available, along with an overview primer on the project.

A June 2018 workshop explored ideas and case studies relevant to flood management in the Chilliwack area of the Fraser Valley.  The workshop drew over 50 participants, including members of the Joint Program Committee for Integrated Flood Hazard Management, members of the LMFMS advisory committees, First Nations leaders and staff, and federal, provincial and local staff having responsibilities relevant to flood management. The sessions were followed by a field tour to case study sites.

Many thanks to workshop speakers Dr. Mike Church (Professor Emeritus, UBC Geography), Mike Pearson (Pearson Ecological), Neil Peters (Retired Provincial Inspector of Dikes), Brent Baron (Indigenous and Northern Affairs Canada), Lory Oberst (Housing Manager, Skwah First Nation), Chief Robert Gladstone (Shxwha:y Village) and Frank van Nynatten (Assistant Manager of Environmental Services, City of Chilliwack).
