A federal agency has approved two permits for a hydroelectric dam developer to study the Little Colorado River located on Navajo Nation for their applications to build up to four dams.
However, in early March the same developer, Pumped Hydro Storage, submitted a third groundwater dam application in Big Canyon, which is a dry canyon attached to the Little Colorado River. The Federal Energy Regulation Commission (FERC) has yet to accept the application for Big Canyon, according to Pumped Hydro.
