The main purpose of this legislation, known as the Help Hoover Dam Act, is to allow the Secretary of the Interior to use funds from the Colorado River Dam fund for various activities related to the Hoover Dam. This includes operations, maintenance, and improvements necessary for the dam's continued function and safety. Key provisions of the Act include the authorization for the Secretary of the Interior to spend money that has been recovered on a non-reimbursable basis. This means that the funds can be used without the expectation of repayment.
