The U.S. House of Representatives has passed a bill that would free about $50 million in funds for maintaining Hoover Dam. House members approved the bipartisan Help Hoover Dam Act on Thursday as part of a larger appropriations bill. It now moves to the U.S. Senate for approval. Lawmakers say the measure will allow the Bureau of Reclamation, which manages Hoover Dam’s operations, to access about $50 million in stranded funding from an orphaned federal account. The bureau could then use the money on operations, capital improvements and clean-up actions.
