The Bush administration has proposed about 16 million dollars for what it calls its "open rivers" initiative for Dam removal. The object of the game is to remove some of the two million small, obsolete, dams that hamper fish migration.
"Dam removals have increasingly become the preferred way to open rivers for fish. Even the best fish ladders are not as effective as an open river plus, they require ongoing maintenance. Dam removals are cheaper than fish passage. In Pennsylvania, the average cost of dam removal is $30,000. The average cost of a fish passages is $35,000 per vertical foot."
