Regional district of kootenay boundary
The Regional District has been busy all year working on our existing Christina Lake Invasive Species programs including exploring new options to help manage further spread of Eurasian watermilfoil. We would like to thank everyone who took the time to attend a meeting, participated in the benthic mat program, visited our Join the Conversation Page, submitted a survey, asked questions or even just waved at the dive crew. Your participation, feedback and input are paramount in guiding the decisions that the RDKB makes.
ProcellaCor FX
After a summer of consulting with the community, we are pleased to share the final report from Keefer Environmental in regard to ProcellaCor FX. As a reminder, this report was not to result in a decision on using the product but rather as a way to gather and share the collective feelings and opinions of the community towards the possibility of exploring the use with the province. This link will take you to our Join the Conversation Page where you will find the final report.
Benthic Mats
With the addition of four new properties for 2025, the RDKB now has 4 fragrant waterlily sites as well as 6 milfoil sites approved for the floating benthic mat pilot project. The RDKB is excited to announce the expansion of the Benthic Mat program as we have received provincial approval to launch our Floating Benthic Mat – Waterfront Property Owner Partnership Program. Please stay tuned for further information on how to see if your property can be part of the program.
Dive Crew
For 2025, the dive crew was able to treat every residential site on the lake once. The estimated number of plants removed in 2025 is 657,249. This is in comparison to the number of plants removed in 2024 (870,895), 2023 (673,371), 2022 (646,398) and 2021 (703,847). The dive crew continued to see extreme levels of milfoil in the south end of the lake, where there can be multiple daily truckloads of weeds removed per site, per day. The number of plants removed was also influenced by the application and expansion of the benthic mat pilot, where mono-culture milfoil areas were controlled passively, and little milfoil was removed from said locations.
Save the Date
RDKB team members will be at the Christina Lake Welcome Centre on November 17th between 9am and noon to meet with community members. A formal presentation will not be provided however, we will be on location to talk about the various invasive species programs, the Keefer report as well as to talk to any landowners who may be interested in joining the Floating Benthic Mat – Waterfront Property Owner Partnership Program.
