With invasive mussels, there are no eradication possibilities at this time, so we're dealing with annual management costs. In Ontario alone it costs nearly $100 million annually to manage invasive mussels. We really don't know how much it could cost, given the impacts to our region. As Anna Warwick Sears said, the region of Okanagan Shuswap is so important to the water systems that we have, so the cost is astronomical and eradication is not possible.
