Lawmakers in Congress on Friday introduced a bill that would pump tens of billions of dollars into fixing and upgrading the country’s dams.

The Twenty-First Century Dams Act, introduced by Democratic U.S. Rep. Annie Kuster of New Hampshire, proposes to spend nearly $26 billion to make the repairs that would enhance safety and increase the power generation capacity of the country’s 90,000 dams. It also calls for removing any dams that have outlived their usefulness.
