Flood Map Study

National Disaster Mitigation Program (NDMP)


In the spring of 2019 the Regional District of Central Kootenay completed a Risk Prioritization Study to identify areas at risk for flood and debris flow geohazards throughout the region. The Risk Prioritization Study was the first step in a series of projects that will enable our communities to be prepared for peak river flows, intense rain storms and other extreme weather events. Our goal is to support land use planning and to help our communities be resilient to flood related emergencies.

Project Description

This summer the Regional District of Central Kootenay is undertaking the next step - region wide assessments to update existing flood mapping. 

Field crews will be performing work on the ground throughout the summer of 2019. Field crews will be walking and recording geological details related to flood processes. Crews may make survey measurements and may take channel sediment samples by hand. Bathymetric surveys will also be completed. The survey work will be done on foot over the river banks and using a boat for the in-channel portion of the survey. The boat will be launched from public launches and the crew will travel to the site. There may be a few laths (survey stake) placed temporarily on the river banks to aid the field crew during their survey. These laths will be removed once the survey is complete. No heavy equipment will enter the foreshore and no soil disturbance will occur during the surveys.

The data collected from bathymetric surveys and/or field work will be used to create detailed flood maps. Field work will be performed on the following water bodies:
