Stanislaus River Grist Mill contributes to the Knights Ferry Historic District.

The 1936 photographs are from the Historical American Buildings Survey.

An informational plaque at the site reads:

Tulloch's Mill

In the late 1850's, David Locke built Knights Ferry's first flour mill. It was destroyed by the flood of 1862, and a new mill was built here by David Tulloch.

A dam upstream diverted water to a water wheel which turned the millstone.

Before the turn of the century, Charles Tulloch, David's son, converted the flour mill into a hydroelectric plant. This plant provided electrical power for the surrounding countryside until the late 1920's.
