The Sustainable Rivers Project (SRP) is a partnership between the United States Army Corps of Engineers and The Nature Conservancy to define and implement environmental flows through adaptive dam management. Formally launched in 2002, the SRP consists of demonstration site work, staff exchanges, and joint training and software development. There are currently demonstration sites in eight river systems containing 36 Corps dams. Site work is helping improve science and engineering and programs and policies to allow for innovative water management practices to be transferred to the hundreds of dams the Corps operates across the nation.
