Check out this Youtube video for more information on zebra and quagga mussel.


Keep these species out of the Crown of the Continent:

Zebra Mussel Dreissena polymorpha

Black-brown to white-yellow, with zigzagged patterns. Triangular shape with a curved outer margin. Found in lakes, reservoirs and slow moving rivers. Attaches to any hard surface with its byssal threads, native mussels do not attach to surfaces.

Quagga Mussel Dreissena bugensis

Color bands range from black to brown to cream with few to no zigzag patterns. Shell is curved at the outer margin and tapered near the hinge. Found in lakes and reservoirs. Attaches via byssal threads to any hard surface, native mussels do not attach to surfaces. May also partially bury in sediment.


Eurasian Water Milfoil Egeria densa 

The whole plant is generally less
than 4 meters tall. Flower spikes are
5–20 cm long. Its color is light brown, green, or red
stemmed, with green leaves. Leaves are
occasionally dark red at the stem tips and flowers are pink.
The stem supports leaves in whorls
of 4 with 12–28 pairs of thin, pinnately
divided, feathery leaflets. Leaflets are
often square at the tips and there are
typically more than 14 per leaf. Flowers
grow in 3–10 whorls and have 4 petals,
often emerging from the end of stems as

spikes in July and August.



Aquatic Invasive Species (AIS)

Aquatic invasive species are non-native plants or animals that can have negative impacts on our health and threaten commercial, agricultural, aqua-cultural or recreational activities dependent on lakes and rivers in the Crown of the Continent Ecosystem.

Aquatic invasive species can spread quickly and can live out of water for up to 30 days. Once introduced to a waterbody, they are virtually impossible to eradicate. Aquatic invasive species can not only damage your boat and equipment, but can cause millions of dollars in damage by to infrastructure by clogging power plant and water intakes as well as irrigation piping and canals.

What Can You Do?

People play an important role in protecting waterways from aquatic invasives. Everyone that enjoys lakes and rivers needs to be proactive about keeping our aquatic ecosystems safe. If you are using your boat in a number of different waterbodies, or especially if you bring a boat from another province or state, make sure to clean, drain and dry your boat and equipment.

CLEAN: Clean and inspect watercraft, trailer and gear.  Remove all plants, animals and mud at the access area or dock.  At home, soak your gear in a 2% bleach solution for one minute (20 ml of bleach per litre of water).  Rinse, scrub or pressure wash your boat away from storm drains, ditches or waterways.

DRAIN: Drain all water from bait buckets, coolers, livewells, bilges, ballasts, transom motor and internal compartments on land before leaving the waterbody.  Never release live bait into a waterbody or transfer aquatic plants or animals from waterbody to another.  For paddle boats, drain by inverting or tilting the watercraft, opening compartments and removing seats if necessary.

DRY: Dry the watercraft and gear completely between trips and allow the wet areas of your boat to air dry.  Leave compartments open and sponge out standing water.

Crown Managers Partnership Efforts on Aquatic Invasive Species

Invasive species are one of the seven Ecological Health Project indicators, both terrestrial and aquatic invasive species are included in invasive species indicator.

The CMP has chosen aquatic invasive species (AIS) as the first indicator for which we will define a desired trans-boundary outcome for the Crown of the Continent Ecosystem (CCE) and the inter-jurisdictional trans-boundary protocols to achieve that outcome. Work is currently underway on the trans-boundary protocol with amibitions for this to come into effect the fall of 2013.

Regional outcome: The CCE remains free of infestation by the most devastating AIS that are already present in much of North America and are causing severe negative environmental, economic and social impacts.

Objective: Keep the CCE lakes, rivers and streams free of zebra and quagga mussels and eurasian water milfoil.

Indicators: Eurasian Water Milfoil, Zebra and Quagga mussels.

Standard: Zero presence

Approach: An initial pilot AIS prevention strategy is being developed and implemented in the Alberta portion of the CCE as there was no AIS prevention strategy in place. The pilot project began with an AIS risk assessment workshop that was held in Waterton in the fall of 2012 that would lead to the development of a five pronged strategy entailing: communications, education and outreach; inspections; monitoring; legislation, policy and planning; and establishing a 1-800 number. Currently the Alberta AIS program is operating in the SW portion of the province and is staying connected with Montana and British Columbia in their AIS prevention efforts.
2013 workplan:
Implement an initial AIS strategy in the Alberta portion of the CCE.
Draft a trans-boundary protocol for the CCE, based on the Alberta, Montana and B.C. experiences.
