A Little Bit of History and Background of the Great Salt Lake
The first non-native to view the Great Salt Lake was most likely Jim Bridger in 1824. The Spanish missionary explorers Dominguez and Escalante learned of the Great Salt Lake from the Native Americans in 1776, but they never actually saw it, getting no closer than Utah Lake forty miles to the south. There was some thought that the lake might be an arm of the Pacific Ocean until James Clyman and three others circumnavigated the lake in 1826 using a "bull boat" which was most likely a type of skin canoe. Interestingly enough, map makers persisted in drawing imaginary rivers draining to the Pacific Ocean for years to come.
How deep is the lake? The level of the lake fluctuates, but at normal levels (4200 ft MSL) the average depth is 15 feet. The maximum depth is about 31 feet. In recent history the lake level has varied from 4191 to 4212 feet MSL. The current lake level is shown on the following link. http://water.usgs.gov/ut/nwis/uv/?site_no=10010000&PARAmeter_cd=00065,00060,00010,72020 How big is the lake? How salty is the lake? Salinity varies inversely as the lake level. As the lake rises
(more fresh water) the salinity drops. Because the south arm receives all
of the fresh water, and since the causeway prevents adequate circulation, the
south arm is less saline (currently about 9%) than the north arm (currently
about 25%).
The saturation point of salinity is around 25%, so the north arm is now saturated, and the south arm is getting fresher. This is not good because it will eventually change the entire GSL ecosystem. This imbalance is visible in the causeway photograph where the water north of the causeway is noticeably red due to the bacteria concentration in the super saturated water. Does the lake really smell that bad?
What are brine flies? They sound dangerous. Do they bite? Brine flies are small flies that usually hatch in late June, and
live until the first frost. They do not bite. Brine flies and the brine shrimp provide food for the myriad of shore birds that live by or visit the lake each year. What precautions need I take to protect my boat from the salty water? Normally all that is required is a thorough washing of the boat and oars with fresh water that is available at the GSLR dock from April-November. The water is cut off at the marina during the winter months. Many members bring a few gallons of water with them during these months to wash the boats and the oars. Does anything live in the lake?
