As the Great Salt Lake shrinks, state agencies usually report its elevation in terms of feet above sea level. On Thursday, at the Saltair Boat Harbor, that number was 4,192.9 feet above sea level.
But that number can make it difficult to understand just how deep — or shallow — the lake actually is.
Watch the video here.
The Great Salt Lake measured about 25 feet deep at its deepest point this summer, reported Dave Shearer, Great Salt Lake State Park manager and harbor master.
The lake hasn’t always been so shallow, but over the last two decades, the Great Salt Lake has experienced a long, steady decline — partly due to drought, but also from new housing developments, farms and industries that divert water from rivers that once fed the lake.
Receding water levels expose large sections of lakebed. Dust from areas previously covered with water contains unhealthy levels of particulate matter that impact the air that millions of people who live on the Wasatch Front breathe.
And, recent research revealed that the Great Salt Lake’s exposed lakebed is a major source of planet-warming emissions. As microorganisms feed on newly exposed organic matter, they release carbon dioxide and methane, two gases known to contribute to global warming.
