To feed these mines, the dam at Carson Tahoe Lumber and Fluming Company's Marlette Lake was increased, and Hobart Reservoir was created, and a number of flumes and pipelines were built to transport water down to Virginia City.

Mexico City is an example of a sinking city that is neither coastal nor low-lying. The city was originally constructed by the Aztecs above a large aquifer in the 1300s. Subsidence was originally caused by the loading of large Aztec and Spanish structures. The city grew rapidly during the nineteenth century, and with it, so did the demand for water.
Subsidence frequently causes major problems in karst terrains, where dissolution of limestone by fluid flow in the subsurface creates voids (i.e., caves).If the roof of a void becomes too weak, it can collapse and the overlying rock and earth will fall into the space, causing subsidence at the surface.
