Flood Projects in the Thompson River Watershed
New flood projects were completed in Thompson River Watershed in 2019-2020, and the final project deliverables are available.
Final Report Available
The final report is now available for a base-level flood hazard mapping project in the Thompson watershed.
GIS files are also available on request for flood projects. Requests can be made to the .

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