Bureau of Reclamation Transparency Act - Directs the Secretary of the Interior to submit to Congress, make publicly available, and biennially update an Asset Management Report that describes the Bureau of Reclamation's efforts to: (1) maintain in a reliable manner all reserved works (buildings, structures, facilities, or equipment owned by the Bureau for which operations and maintenance are performed by Bureau employees or through a contract with the Bureau) at Reclamation facilities (infrastructure assets that are owned by the Bureau at each Reclamation project owned by the Bureau); and (2) standardize and streamline data reporting and processes across regions and areas for the purpose of maintaining such works.

Requires such Report to include: (1) a detailed assessment of major repair and rehabilitation needs for all such works; and (2) an itemized list of major repair and rehabilitation needs of individual Reclamation facilities at each Reclamation project, including a budget level cost estimate of appropriations needed to complete each item and an assignment of a categorical rating for each item consistent with existing uniform categorization systems to inform the annual budget process and agency requirements.

Directs the Secretary to: (1) coordinate with the non-federal entities responsible for the operation and maintenance of transferred works (Reclamation facilities at which operations and maintenance are carried out by a non-federal entity under a formal agreement with the Bureau) in developing reporting requirements for Asset Management Reports regarding the condition of, and planned maintenance for, transferred works; and (2) develop and implement a categorical rating system for transferred works.
