Morman Springs Mill 1845-47

Mormon Springs derived its name from the Mormon colony that established a grist- and lumber mill there in the mid-1840s. Under the leadership of Lyman Wight, a dissenting faction of the Mormon faith arrived in eastern Travis County in 1846 and pitched their tents briefly at Webberville. Moving westward soon, they settled on the Colorado River a few hundred yards below Mount Bonnell. The group included a number of artisans and tradesmen, who were later awarded the contract to erect Austin's first jail.

The mill was destroyed by a flood in 1847. When attempts to rebuild it failed, the Mormons moved again, first to the Pedernales River near Fredericksburg, and later to Hamilton Creek near Burnet, where they built another mill. Beset by financial difficulties, they sold the mill to Noah Smithwick in 1853, when the members scattered. A few remained with Wight until his death in 1858. Others reunited with the major Mormon colony that had settled in Salt Lake City with Brigham Young.

Lower Waller Creek Mill 1840

This mill was located in central Austin on Waller Creek somewhere downstream of 15th street and above the Colorado river. Only one reference to this mill exists. 1840 is given as the date. It is not known if Edwin Waller was the builder. The following is from the Texas handbook online

"In April 1839 President Mirabeau B. Lamar sent Edwin Waller, in charge of a company of workmen, to the site chosen for the capital with instructions to lay out the city and construct temporary quarters for government offices. By October the work had been completed. There is general agreement that Waller, who became Austin's first mayor, carried out his assignment with distinction. Waller Creek was so named, it is surmised, by one of his surveyors."
