In 2015, the CRVWA launched an Adult Invasive Mussel Monitoring (AIMM) project at Wakaw Lake.  13 substrate samplers were placed in the lake at participating lakefront property owners’ locations, either deployed from a dock, boat launch, or other feature directly in the water.  These substrate samplers are made up of lengths of PVC pipe with concrete filling about half of the pipe section.  Bolts are attached to secure a rope to the sampler, and then the rope is attached to the volunteer lakefront property owners’ dock or boat lift.  These samplers provide a firm surface for the zebra and/or quagga mussels to attach to, should there be adult mussels of these species present in the waterbody.  Unlike native mussels, which prefer the soft, sandy lake bottom, zebra and quagga mussels prefer to live on firm surfaces.  The Saskatchewan Ministry of Environment has created a fact sheet with more information about zebra and quagga mussels.

Our AIMM project expanded in 2016 to include substrate sampler locations at Kipabiskau Regional Park and the Resort Village of Tobin Lake, as well as continued monitoring of substrate samplers at Wakaw Lake.  For more information, or to become involved, contact our office at 306-752-1270

As part of the AIMM project, we have partnered with the Saskatchewan Ministry of Environment to promote Clean Drain Dry.  Clean Drain Dry is a practice that can easily be adopted by recreational boaters, and involves visually inspecting boats when they are taken out the water; removing any debris (including plants, mud and animals); wash using high pressure, hot tap water away from storm ditches, drains and waterways; draining all on board water from live wells, bilge, ballast tanks and motors; and thoroughly dry watercraft, equipment and all related gear.  Watch this video for more information about Clean Drain Dry, or contact our office to arrange a Clean Drain Dry demonstration at your lake or event.

It is also important to properly dispose of unwanted or leftover bait; and aquarium pets, plants and water into the trash.  These items can include plants, animals and pathogens that have the ability to become invasive in our native water bodies.  Never release or dispose of them into wetlands, lakes, rivers, or streams.
