Chief hydrologist at the USGS in the early 1900s, E.C. LaRue documented and studied all dam sites on the Colorado River. Below are some of images from his reports.
Two subsampled false color landsat images of the lower Colorado river delta that capture a drought in May 24 and 25 1990, and the maximum inundation recorded by Landsat from scenes of June 9th and April 13th 1984 caused by abnormal snowmelt in the upper basin. The extent of the inundation in the lower delta was 2,500 km2 . The reason for two dates to create a snapshots, is that two Landsat scenes from different orbits (dates) are needed to capture the entire lower delta.
