One of the most impressive sawmills constructed on the Susan River was the Bremner Mill. In 1886, Lawrence, Leavitt & Company was formed to construct and operate it. The site selected on the Susan River was approximately a mile west of Susanville. The firm built an imposing dam 250 feet long and 25 feet high. The dam created a reservoir that backed up water for a mile. That was beneficial for the company, since it would float logs down the river to the mill.
In December 1887, Charles Bremner, a lumberman from Maine, purchased the mill. His two sons, James and William, arrived from Maine to assist. On December 8, 1888 Bremner sold a half interest. in the mill to Alex McCrimmon. The partnership short-lived. McCrimmon was not pleased with Bremner’s management of the company funds, and sold his interest to Leavitt & Woodsum for $1,800. Bremner was plagued with financial problems. In 1892. with Bremner unable to pay his debts, William Greehn foreclosed on the property and became the new owner. Greehn, however, retained Bremner to operate the mill.
In 1891, to take advantage of the water power from the dam, James Anthony installed a power plant, to generate the first electric power for Susanville. The generator had a capacity of 30 horsepower, enough to provide power for40 arc lamps.
On Tuesday night, August 14, 1894, fire broke out at the mill. It went unnoticed by the several people who were at the mill. Once it was discovered the building was in flames and it was too late to suppress it. The mill machinery and Anthony’s electric plant were a total loss. The origin of the fire was never determined. The mill was not rebuilt, and Anthony built a new electric plant half a mile down from the dam.
