As the science provider to the Glen Canyon Dam Adaptive Management Program (GCDAMP), GCMRC designs and implements scientific studies to meet the objectives put forward by resources managers of the GCDAMP. In addition to its role as the science arm of GCDAMP, GCMRC is also responsible for disseminating both the data collected in support of science objectives as well as the results of the studies conducted. \n\nThis online service provides base GIS layers most commonly used by the U.S. Geological Survey's Grand Canyon Monitoring and Research Center.
