Congress will soon consider a bill that includes a provision to close a key Mississippi River lock to slow the spread of invasive carp.
Minnesota's congressional delegation pushed for the provision to close the Upper St. Anthony Falls lock in Minneapolis. The measure is in the water infrastructure bill, which now goes to the House and Senate for final votes.
Invasive carp have been found in Minnesota, but experts have not found any evidence that they are yet breeding in state waters. Supporters of the move to close the St. Anthony Falls lock within one year say it would prevent the invasive fish from moving northward and threatening Minnesota's lakes and streams.
The Minnesota Department of Natural Resources and many environmental groups support closing the St. Anthony Falls lock.
