In the past century, we've built more than 75,000 dams. Dams for reservoirs, dams for hydroelectric power, dams for flood control, irrigation and recreation. But thousands of these dams no longer make sense. In fact, some old dams are public safety hazards. But the bottom line in dam removal is cash flow - not water flow.
Owners remove a dam when it's cheaper to wreck it than to run it.
There's money in the banks of a health, free flowing river. The EnvironMinute is produced in cooperation with the National Safety Council and made possible by the Teresa and H. John Heinz III Foundation.
