Conservation Minnesota has been working with a broad coalition of organizations to stop the spread of Asian Carp through the waterways of our state. We must stop Asian carp now – before they swim further north into Minnesota and cause irreparable harm to our rivers, lakes and streams that support the $11.6 billion a year recreation and tourism industry. Delay would be catastrophic for the people who depend on Minnesota's waters for their jobs and for all of us who love our lakes, rivers and way of life. Together, we are pushing hard for practical measures including the closure of two underutilized locks on the upper Mississippi. It is clear that lock closure is the only 100% effective method of prevention. But it is just one of several steps that must be taken to address this threat. Please take a look at the letter our coalition has sent to legislative leaders this week. Then click here to send your own message to your legislators and ask them to help address this serious problem.
