- For health and safety reasons the groyne needs to be marked. During the Summer and Fall of 2022 PSPC engaged with First Nations, local governments and the public about the marker installation. Public feedbacks and comments have been received and will be considered for selection of marker option.
The Lake Windermere groyne has deteriorated over the years and presents a risk to boaters and a risk of environmental damage, especially due to accidents. In its current condition, the Lake Windermere groyne poses a potential hazard to navigation and should be marked for safety reasons.
A groyne is an underwater structure that deflects river currents. Navigation markers are required to mark the groyne for health and safety reasons. We propose 3 options for these markers and after the engagement will proceed to chose and install one option to be the continuing navigation markers.
Navigational markers, including navigation signs and floating buoys, are used to alert boaters to underwater hazards. All of the proposed markers are safe for the environment and would not pose a safety concern for anyone using the lake.
Lake Windermere is located near Invermere in southeastern British Columbia, within the Columbia River Valley. At 17.7 kilometres in length, it is one of the largest lakes in the region, and also has one of the warmest water temperatures.
Options to mark the groyne in Lake Windermere
PSPC has identified 3 options to mark the groyne:
Option 1: Tall marker piles
Option 1 is 11 untreated wood piles, driven into the lake bed, with 5 metres of the marker pile showing at low water levels. There would be a navigation sign on the pile at the eastern end of the groyne to tell boaters where the navigation channel is.
Option 2: Short marker piles
Option 2 is 11 untreated wood piles, driven into the lake bed, with 3 metres of the marker pile showing at low water levels. There would be a navigation sign on the pile at the eastern end of the groyne to tell boaters where the navigation channel is.
Option 3: Marker buoys
Option 3 is 11 buoys, including 1 navigation buoy and 10 hazard buoys. Each buoy is anchored in place and is comprised of a strong plastic shell over rigid floatation foam, intended for in-water use. The lines to the anchors are non-floating and will not entangle swimmers or boat propellers even if they come in contact with the buoy.
Our records show that we built the groyne in Lake Windermere in the 1800s for steamships on the Columbia River. It has wood cribbing and rocks placed on top of a brush mattress.
Since we built the groyne, it is an asset under the department’s responsibility. As such, we are obligated to ensure:
- that it meets all regulatory requirements
- the safety of boaters using the immediate area of the groyne
- that changes in its condition do not cause environmental damage
Because the groyne extends from shallow water, near the west shoreline of the lake, to the shallow navigation channel on the east side, markers are required for its full length.
We installed temporary marker buoys in fall 2020, which will remain in place until a continuing solution has been found. Any markers selected will still need to meet the requirements of the federal Navigation Protection Program.
