To read the Phase 1 Summary Report of the Lower Mainland Flood Management Strategy and to access full technical reports and maps, see Phase 1 Results.

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.


Flood Strategy Briefing


The Flood Strategy Briefing provides updates on the strategy development to LMFMS partners and others interested in regional flood planning.


Materials from several of the LMFMS workshops have been posted for convenience of participants.

Workshop: Fraser River Flooding, Flood Management and the Environment

June 26, 2018


A workshop and field tour in June 2018 offered the opportunity for flood managers and others in the LMFMS to visit the Browne Creek Wetlands in the Vedder Greenway, on the south side of the Vedder River in Chilliwack. Because dikes were set back from the river, it was possible for wetlands project partners (DFO and the Fraser Valley Watersheds Coalition) to create salmon spawning channels and for the City of Chilliwack and Rotary Club of Chilliwack to create prime recreational trails that connect the people with the water, while also better protecting the flood infrastructure.

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).

About the Fraser Basin Council

The Fraser Basin Council (FBC) is a charitable non-profit organization that brings people together to advance sustainability in the Fraser River Basin and throughout BC.

We work with people in multiple sectors, helping them find collaborative solutions to today’s issues through a commitment to the social, economic and environmental dimensions of sustainability. Our focus is on healthy water and watersheds, action on climate change and air quality and strong, resilient communities and regions.
