These data represent the centerline and measured increments at hundredths, tenths and whole miles, along the centerline of the Colorado River beginning at Glen Canyon Dam near Page, Arizona and terminating near the inflow s of Lake Mead in the Grand Canyon region of Arizona, USA. The centerline was digitized using Color Infra-Red (CIR) orthophotography collected in March 2000 as source information and a LiDAR-derived river shoreline representing 8,000 cubic feet per second (CFS)as the defined extent of the river. Every effort was made to follow the main flow of the river while keeping the line approximately equidistant from both shorelines. The centerline feature class has been created to more accurately map locations along the Colorado [...]

This data set was developed to provide a geospatial river measurement system to be used by scientists performing research along the Colorado River between Glen Canyon Dam, near Page, Arizona and downstream to Pearce Ferry, near Lake Mead. The data serve as a common reference system used for tracking and identifying site locations, reach extents, and other applicable uses related to geo-locating scientific research and analysis through the Colorado River corridor.
