The GCMRC was created by the Secretary of the Interior and placed under the USBR following completion of the Glen Canyon Dam EIS to fulfill the directive in the Grand Canyon Protection Act for the “Establishment and implementation of a long-term monitoring and research program to ensure that Glen Canyon Dam is operated in a manner that protects the values for which the Grand Canyon National Park and the Glen Canyon National Recreation Area were created.” (Deputy Assistant Secretary for Water and Power, 1995). Glen Canyon Environmental Studies program merged into GCMRC.
