Two West Virginia rivers are now listed among the nation's 10 most endangered.
At number 1 on American Rivers' annual list is the Potomac.
It provides drinking water and recreation for more than 5 million people in Virginia, Maryland, Pennsylvania, West Virginia and Washington, D.C.
Steve Chaconas with National Bass says the river is far less polluted than it was in the 1960's. He says recycling at home, using lawn fertilizer responsibly and not litering can add to the health of the river.
