Lower Colorado River Programmatic Environmental Impact Survey (Draft)

The Lower Colorado River Basin Study was conducted in response to authorization from the Congress of the United States and in cooperation with non-federal sponsors. This Programmatic Environmental Impact Statement (PEIS) focuses on various potential U.S. Army Corps of Engineers flood damage reduction and ecosystem restoration measures including potential projects that are being investigated as part of the Lower Colorado River Basin Study. Reasonably foreseeable projects by other entities are also identified, and the potential direct and cumulative impacts resulting from the implementation of the potential U.S. Army Corps of Engineers and other entities’ projects on the human and natural environment are assessed. The document defines the baseline conditions within the basin, examines past actions of the U.S. Army Corps of Engineers and other entities within the study area, and then examines reasonably foreseeable alternatives of the U.S. Army Corps of Engineers and of others that might affect water and related land resources.
