Zebra Mussel Containment and Treatment – Riding Mountain National Park

5P420-24-0038 Zebra Mussel Containment and Treatment – Riding Mountain National Park

REQUIREMENT

Parks Canada requires urgent support to manage and potentially eradicate zebra mussels in Clear Lake, MB. The initial Phase of the project will entail hydrological isolation of the anticipated areas, with additional treatment Phase(s) to be optioned should viable population(s) of zebra mussels be confirmed in the containment areas.

The treatment Phase, if optioned, will employ the use of Potassium chloride (KCl, also called potash) applications. KCl has been shown to be effective in killing zebra mussels at all life stages.

Phase 1 - Required and Immediate: Containment Curtain

The Contractor must establish three (3) containment areas A, B, and C (see Figure 1 for proposed areas) and install a curtain that is of sufficient depth and length to isolate the predetermined area(s) allocated for a treatment using potash (estimated ~2000 meters in length).
• Option A and B – A perimeter curtain will be installed to connect the shoreline west of boat cove approx. 200 m. The perimeter curtain for these options will a distance of 1200 m and connect to the main pier structure that is evident between options B and C (Figure 1). A second curtain will be required, extending from the perimeter curtain to the shoreline approx. 241 m in length, to create a division between options A and B. A third curtain will be required at the southern extent of the main pier structure (70 m in length) to create a division between option B and C, where there is an open span bridge that allows the passage of water.
• Option C – A perimeter curtain will be required to connect the main pier structure to the shoreline, extending in an east direction approx. 450 m in length. A slight variation in the curtain dimension on the northeast side of the main pier will have to be allowed for the mooring of multiple vessels.

Phase 2 – Optional and Estimated:

If exercised, the Contractor will administer treatment using Potash Molluscicide (Potassium Chloride) to one or more of the delineated areas as outlined by PCA project authority – the area can be assumed to be between 10 and 30 ha in surface area size with depths to 7 meters (Figure 1). Before a treatment is administered a detailed inspection of the containment curtain must be completed to ensure complete hydrological isolation.

PERIOD OF CONTRACT / DELIVERY DATE

The period of the Contract is from date of Contract to November 30, 2024 inclusive.
