Following the establishment of Merced County and the independence of California from Mexico, many settlers came to the Merced River area and established small towns on the Merced River. One of the first was Dover, established in 1844 at the confluence of the Merced River with the San Joaquin River. Dover functioned as an "inland seaport" where boats delivered supplies from the San Francisco Bay area to settlers in the San Joaquin Valley. Some towns that followed were Hopeton, Snelling and Merced Falls, the latter named for a set of rapids on the Merced River near the present-day site of McSwain Dam. In the late 1880s a flour mill, woolen mill and a few lumber mills were constructed at Merced Falls. The Sugar Pine Lumber Company and Yosemite Lumber Company operated lumber mills at Merced Falls for over thirty years, relying on narrow-gauge railroads to ship lumber from the Sierra Nevada along the Merced River. Following the construction of the Central Pacific and Southern Pacific Railroads, many of the river towns on the Merced River were deserted. Several cities that did achieve prominence, however, include Merced and Turlock, both located on the railroad.
