Corps of Engineers Reform Act of 2011 - Directs the Secretary of the Army, acting through the Chief of Engineers, to establish a program to make grants to states to carry out harbor maintenance and deepening projects in accordance with the priorities determined by each participating state. Amends the Internal Revenue Code to establish in the Harbor Maintenance Trust Fund a separate State Harbor Maintenance Block Grant Account to fund such grant program. Requires the chief executive officer of a state to designate a state agency to administer the financial assistance received, develop the state plan to be submitted to the Secretary, hold at least one hearing to provide the public an opportunity to comment, and coordinate the implementation of harbor maintenance projects with applicable federal, state, and local agencies.

Provides for a pro rata reduction of allotments in the event of insufficient funds.
Directs the Secretary to publish: (1) annually, a list describing each authorized water resources project of the Corps of Engineers in the Federal Register and on a publicly available website, and (2) a list describing each water resources study or project of the Corps that is no longer authorized.
