The extent of lake lahontan reached its maximum at the peak of the wisconsin glacial melting, some 12,700 years ago, its former boundaries now marked by tufa limestone formations that were deposited in its shallows; then, as the climate began to warm, the lake began to shrink, eventually separating into a maze of smaller basin lakes.

The area contains many subbasins and interbasin thresh olds, and is fed by several major streams, so the history of lake rises and declines probably was complex. For example, if water stood at 1220 m (4000 ft), four separate lakes would exist. Furthermore, understanding of lake lahontan is hindered by incomplete topographic mapping.
Lake lahontan was 500ʼ deep in the black rock desert, and 900ʼ deep at present-day pyramid lake. Lake lahontan dried up due to increased evaporation as the climate warmed.

A model of lake ice was coupled with a model of lake temperature and evaporation to assess the possible effect of ice cover on the late-pleistocene evaporation rate of lake lahontan.

Lake lahontan’s history begins approximately 12 to 15 ma with the final stages of the great basin’s formation. During this period, the upper plates began a series of faults that were upward steepening and that surfaced as normal faults.
Though this body of water has been around for 23,000 years, lahontan reservoir was originally dammed as part of an irrigation project—the newlands project—to supply water to farmland in the fallon area. In 1905, lahontan became the first to deliver water from works constructed by the bureau of reclamation.
