Project Background

The flood hazard mapping is intended to fill basic information gaps identified in the Thompson Watershed risk assessment. It is at a base (screening) level, covering 478 square km across 11 floodplain sites in the Thompson-Nicola Regional District and one site in the Cariboo Regional District.

The outcomes include hydrologic analysis results and screening-level flood hazard maps at a level of detail suitable for:

• Identification of sites that may be subject to flood hazards
• Prioritization of sites for detailed study
• Conversations at the community and regional level that centre around flood risk, including mitigation strategies to reduce existing or future flood risk
• Emergency preparedness and response.

The flood hazard mapping project was funded by the Union of BC Municipalities Community Emergency Preparedness Fund program.

Flood Hazard Maps

Flood hazard map layers from this project can be accessed through an online, interactive mapping website.

Also on the site are layers from the 2018-2019 Thompson Watershed risk assessment.

LIDAR Acquisition

Raw topographical data was collected in the Fall of 2019 using light detection and ranging (Lidar) technology, and imagery captured in almost 5000 km² of valley bottom throughout the Thompson River Watershed.

The project data allowed for detailed, up-to-date topographic maps and will support future detailed floodplain mapping. The deliverables of the project are intended to be shared with all orders of government in the watershed.

This data can be accessed by any order of government through the BC Ministry of Forests, Lands, Natural Resource Operations and Rural Development.  to initiate a data sharing agreement and outline your geographic area of interest

This project is funded by the National Disaster Mitigation Program, funded equally by Public Safety Canada and Emergency Management BC.

Advisory Committee

A project Advisory Committee — with representation from elected officials and staff from local government, First Nations and the Province of BC — has provided guidance on this project. Information on the work of the Advisory Committee, and materials related to this work, are available: see Advisory Committee & Resources.
