Most of us around the Shuswap have a creek near our water front property that flows into the Lake, but are we aware of the risks from debris flows that can come down a creek? There have been a number of these debris flows over the years that have caused serious damage to property, and unfortunately also resulted in fatalities. Reports on some of these incidents are available on the CSRD web site, for example from Robinson and McIntyre Creeks:

The CSRD has also recently completed a detailed LiDAR study of the Bastion Mountain area in an effort to identify continuing risks in the general area. LiDAR is a surveying method that measures distance to a target by illuminating the target with pulsed laser light and measuring the reflected pulses with a sensor, and in this case producing a very detailed picture of the topography as a way to identify high risk situations. The report can be viewed at:
The Fraser Basin Council has recently released a compilation and assessment of flooding and land movement risks in the entire Thompson River watershed. This report can be viewed at : https://www.fraserbasin.bc.ca/2018-2019_TWRA_Assessment_Results.html.
To actually see specific areal risk assessments requires signing into the BGC Engineering Cambio Communities graphical information site at:
The CSRD may do further studies, including detailed LiDAR surveys, in other areas around the Lake once it has assimilated the recent FBC data.
We certainly don't want to pretend that we have any expertise in this area, but do want to make our members aware that there may be risks. If SWOA members have questions about their area, a good person to talk with is Derek Sutherland. Derek heads up Protective Services at the CSRD and can be contacted at firstname.lastname@example.org , phone 250 833-5945. In the case of debris flows, ignorance is NOT bliss.
