A Master Plan (MP) is a recreation, natural resource, and land-use management document. Per Chapter 3 of Engineering Regulation1130-2-550 and Engineering Pamphlet 1130-2-550 Corps policy, it is the "...document that conceptually establishes and guides the orderly development, administration, maintenance, preservation, enhancement, and management of natural, cultural, and recreational resources of a Corps’ water resource project." Despite what the name might suggest, it is not a plan for navigation (locks, dams and associated infrastructure for commercial barge traffic), flood risk management (such as levees in the PL84-99 Program), or water level management which are addressed in other guidance documents.
