No dam good

The article focuses on the experiment made by the U.S. Bureau of Reclamation to release more water than it usually does from the Glen Canyon Dam in Arizona. It highlights the experiment as part of the plans in rehabilitating river banks, rebuilding beaches and habitat restoration for the endangered humpback chub, a species of fish. According to Dr. Jack Schmidt, a head researcher on the experiment, the release was only short-term and it needed a frequent release of water to successfully rebuild sandbars and healthy ecosystem. However, with the demand of human for the dam's water and electricity, even infrequent releases of water are compromised.
