EPA’s Eye in the Sky: Great Salt Lake, Utah, USA

Reading Time: < 1 minute

A railroad causeway cutting across the Great Salt Lake, Utah.

Different levels of salinity cause the different colors, with an algae that flourishes in higher salt content causing the red pigment.

Utah’s Great Sake Lake has lost 50 percent of its volume since the arrival of Mormon pioneers in 1847. Two decades of drought are not the only reason for the lake’s shrinking shoreline, above average temperatures, and water diversion for agriculture and drinking water, are also to blame.
