Two plans are currently underway to address high nutrient levels in Elk/Beaver Lake. These plans aim to reduce frequency of blue-green algae, improve fish habitat and manage growth of Eurasian milfoil.
The development of a watershed management plan is underway to address external sources of nutrients through a public engagement process. External sources of nutrients come from various land use activities around the lake (urban or agricultural) as well as natural processes that bring nutrients into the lake. CRD staff are currently facilitating a public engagement process to develop the plan to address this source of nutrients. Please sign up to register for a workshop on Sept 26
and Oct 3
(7:30-9pm) at the Saanich Commonwealth Place to have your voice heard and to be a part of the solution. Following these workshops, staff will develop a draft plan that will be made available to the public for review prior to going to the CRD Board for approval.
The development of an in-lake remediation plan is also underway to address internal sources of nutrients in Elk/Beaver Lake. These nutrients have accumulated over decades in the lake and bottom sediments and are continually recycled back into the water column under low-oxygen conditions. The in-lake remediation process is guided by expert consultants and an intergovernmental working group. On September 11, 2019 staff brought forward a Staff Report and Business Case to the CRD Board outlining the environmental, recreational, community and economic values of the lake (over $10 million annually) and a recommendation to remediate the lake. The CRD Board approved the recommendation to move ahead with the in-lake remediation of Elk/Beaver Lake, subject to receiving at least 50% capital grant funds for the project. This recommendation includes the installation of oxygenation systems in Elk/Beaver Lake to improve water quality at a capital cost of $1.4 million and ongoing operational costs of $100,000 -$150,000 annually. For more details on the CRD Board discussion and decision, watch the video
online (go to Section 8.9 19-755 Elk/Beaver Lake Remediation).
Staff are now working to develop a funding plan to support the project and plan to publish a Request for Proposals (RFP) to develop a detailed remediation plan (sizing and siting) this fall/winter.
Public engagement is a key part of developing the CRD's watershed management plan for Elk/Beaver Lake to address external sources of nutrients and, as a result, the CRD welcomes feedback on this work. A public info session
was held on July 31, 2019.
The next engagement opportunity for residents are public workshops in the fall. Register for a workshop on one of these dates:
Following this initial input from residents, a management plan will be drafted and made public.
