Colorado River Delta - Water For the Environment and Environmental Benefits
First-ever plans to facilitate and promote actions that foster environmental benefits in the Colorado River Delta were set in motion by an historic binational agreement known as Minute 319, which was signed in 2012 by the United States and Mexico. The agreement included a science-based plan for a one-time “pulse flow” release of 105,392 acre-feet (130 million cubic meters) of water from the Morelos Dam near Yuma, Arizona, in March 2014. Remotely sensed images are being used to document the effects of this flow. Pre-pulse baseline vegetation information is being derived from WorldView-2 satellite imagery and lidar data; Landsat and Moderate Resolution Imaging Spectroradiometer (MODIS) data will be used for analyses of the post-pulse biologic and hydrologic effects. Scientific investigations continue in 2016.
