Before 1941, average salinity was approximately 50 grams per liter (g / l) (compared to a value of 31.5 g / l for the world's oceans). In January 1982, when the lake reached its lowest level of 6,372 feet (1,942 m), the salinity had nearly doubled to 99 g / l . In 2002, it was measured at 78 g / l and is expected to stabilize at an average 69 g / l as the lake replenishes over the next 20 years . </P> <P> An unintended consequence of ending the water diversions was the onset of a period of "meromixis" in Mono Lake . In the time prior to this, Mono Lake was typically "monomictic"; which means that at least once each year the deeper waters and the shallower waters of the lake mixed thoroughly, thus bringing oxygen and other nutrients to the deep waters . In meromictic lakes, the deeper waters do not undergo this mixing; the deeper layers are more saline than the water near the surface, and are typically nearly devoid of oxygen . As a result, becoming meromictic greatly changes a lake's ecology . </P>
