The Grand Canyon Trust filed a motion to intervene in the preliminary permit proceeding for the proposed Black Mesa hydropower project. The three-part plan for a hydropower development on the Navajo Nation could string reservoirs for nearly 50 miles along both the rim of Black Mesa and the lands below. According to the preliminary-permit applications, the project could take more water than best estimates say the Navajo Nation uses in total each year. It is five times more water than can be held today in all the significant reservoirs and lakes on the Navajo Nation combined, in a nation where lack of access to water remains a persistent problem.
