Simonsville (occasionally referenced with variant spellings such as Simmonsville) was a short-lived Mormon farming settlement and milling site in Clark County, Nevada. It was situated on the east bank of the Muddy River in the Moapa Valley, west of the south end of the Overton Airport. Coordinates are 36°33′46″N 114°26′40″W, with an elevation of 1,325 feet (404 m). The settlement formed part of the broader network of 1860s Mormon colonies along the Muddy River, established to support agriculture in southern Nevada’s desert environment.
Early History/Founding
Simonsville originated as part of the Mormon Cotton Mission initiated by Brigham Young in the early 1860s. Seeking reliable water from the Muddy River and fertile soil for cotton production (to achieve economic independence for Utah Territory and secure southern trade routes), church leaders dispatched approximately 75–85 families to the Moapa Valley in 1865. The first major settlements were St. Thomas and St. Joseph.
The site was initially known as Mill Point after James Leithead constructed the valley’s first grist mill there. By December 1865, enough settlers had arrived for President Erastus Snow to establish a new colony under the leadership of Orrawell Simons (sometimes spelled Orawell). The settlement was renamed Simonsville in his honor. In spring 1866, Orrawell Simons oversaw construction of an additional grist mill, which quickly became operational.
Economic Activities
The economy of Simonsville centered on agriculture and milling, integrated with the larger Moapa Valley Cotton Mission. Settlers grew cotton, wheat, corn, oats, barley, and orchard crops, supported by irrigation canals drawn from the Muddy River. The grist mill at Simonsville (and its predecessor at Mill Point) ground wheat, corn, and salt for local use and regional supply.
A cotton gin, powered by the same mill infrastructure, processed the 1865 cotton crop; valley-wide production exceeded 5,000 pounds of lint that year, with individual acres yielding up to 695 pounds of first-class lint. By 1866–1867, cotton output grew significantly (e.g., 14,600 pounds of lint reported at nearby St. Joseph alone in 1867). The mill also supported defensive efforts, as a guard was maintained at Mill Point to protect the valuable infrastructure during Indian raids in 1866.
Decline/Abandonment
Simonsville’s decline mirrored that of the other Muddy River settlements. Harsh conditions—including remoteness (450 miles from Salt Lake City), desert climate, malaria, sandstorms, and Indian depredations—strained the colonies. A critical issue emerged when a boundary survey revealed the entire Moapa Valley lay in Nevada (specifically Lincoln County at the time), not Utah Territory or Arizona as initially assumed. This triggered disputes over taxation: settlers faced double levies (Nevada state taxes plus tithing to Utah’s Rio Virgin County) without corresponding representation or services.
In 1870–1871, Brigham Young described the area as a “God Forsaken place” and advised abandonment. Most residents, including those at Simonsville, voted to leave. By 1871, over 600 colonists abandoned their homes, farms, and mills, relocating eastward to Long Valley, Utah (founding communities such as Glendale and Mount Carmel). Simonsville was never reoccupied.
Legacy/Current Status
Simonsville exemplifies the ambitious but ultimately unsuccessful Mormon efforts to colonize southern Nevada’s river valleys in the 1860s. It highlights the challenges of territorial boundary ambiguities, taxation conflicts, and environmental hardships that doomed the Cotton Mission. The settlement contributed to early agricultural experimentation (cotton ginning and grain milling) in what became Clark County and paved the way for later, more permanent communities in the Moapa Valley (such as the revived Overton and Logandale).
Today, the physical site of Simonsville (and original Mill Point) is largely lost. It lies beneath or adjacent to modern Clark County flood-control infrastructure and realigned airport roads. No standing structures remain, and the area is not preserved as a public historic site, though it is documented in lists of Clark County ghost towns.
