In the ongoing saga of hydro dam developments proposed within striking distance of Grand Canyon National Park, American Whitewater is asking for help from the paddling community to stop a development that would impact the greater Grand Canyon area and its tributaries. Back in October 2019, we wrote an article outlining the proposal submitted by Phoenix-based hydroelectric company Pumped Hydro LLC to place two dams on the Little Colorado River, a tributary of the Colorado River’s mighty Grand Canyon. This proposal was met with a large amount of pushback for the cultural impact on indigenous tribes, ecological impacts, and water use. To address these concerns, Pumped Hydro decided to file an alternative (yet equally problematic) proposal for a hydro development on Big Canyon, a tributary of the Little Colorado River. The Big Canyon project permit application has been accepted into the Federal Energy Regulation Commission’s (FERC) registrar, initiating a public comment period on the project ending August 1 and we need members of the paddling community to step up and make their voices heard!
