MINNEAPOLIS - Federal and state leaders are highlighting the Upper St. Anthony Falls Lock and Dam in downtown Minneapolis as a crucial barrier for stopping Asian carp's advance up the Mississippi River.

Sen. Amy Klobuchar and Rep. Erik Paulsen visited the site on Monday to tout legislation they introduced last week to make it easier to close the lock and dam.

Researchers at a nearby laboratory are studying bubble barriers and other potential ways to stop the carp.

Dave Schad, a deputy commissioner of the Minnesota Department of Natural Resources, told reporters no other fish can do as much damage on the state's lakes and streams as Asian carp.
