Death by Disco?

Imagine you had the final say on how to stop Asian carp from invading the northern rivers, streams and lakes of Minnesota which trout, walleye, perch, and northerns call home.

Now, here are your options to do that:

1) Build a bubble, sound and disco lights barrier near Lock and Dam #1 that scientists (and the MN DNR) say wont be effective to stop carp from bypassing it.  The bill for this could be as high as $18 million to build – and $250,000 to operate yearly;


2) Closing Lock and Dam #1 that would permanently block passage of Asian carp or any other invasive species. The bill for this would be much less than $18 million to mitigate the loss of navigation for some industry users of the lock, and perhaps enhance some public access for recreational boaters who would be impacted by the lock closure.

What would you do?
