Many folks interested in Mojave Desert history are aware that in 1776, Francisco Tomás Hermenegildo Garcés was the first non-native American to cross the Mojave from the Mojave Indian villages near Needles at the Colorado River to the Mission San Gabriel near Los Angeles, California. Trapper and explorer Jedediah Smith also crossed the Mojave in 1826 and in 1827.
Not so well known is that both men, when they left the mission at San Gabriel made their way north to the San Joaquin Valley and the shore of Tulare Lake. In tracking the paths of both men in relation to our modern geography it is soon discovered that this lake does not seem to exist.
What happened to Tulare Lake?
The answer to this mystery of a disappearing lake is simple, yet inelegant and predictable:
At the onset of American settlement in the area in the late 1840s, the lake was the largest body of fresh water west of the Great Lakes. Its destruction by the late 1800s because of diking and water diversion for irrigation was one of the most dramatic signs of a major theme in the state’s history: the rapid transformation of the wild California landscape into one dominated almost completely by human action.

So, now you know.
