The Folsom Powerhouse is an example of the tremendous advance in the commercial application of electricity. H.P. Livermore realized that the water of the American River could turn generators for electricity in Sacramento, 22 miles downstream. With his partners, Livermore built the powerhouse, which still looks much as it did in 1895. Vintage generators are still in place at the powerhouse, as is the control switchboard, faced with Tennessee marble. Visitors touring the powerhouse can see the massive General Electric transformers, each capable of conducting from 800 to 11,000 volts of electricity, in addition to the forebays and canal system that brought the water from the dam.

The Society operates two house museums. The 1872 Lee House was home to Dr. Norman Lee, one of Junction City's first doctors. It was originally located in Lancaster and was moved to its present location in the late 1800s using logs and a team of horses; it now displays photos, furniture, tools, and clothing from Junction City's past. The 1871 Pitney House belonged to Mary Pitney (1891—1995), a school teacher, published poet, painter, world traveler, and humanitarian. Born and raised in this house, she lived the later years of her life here; today, it is being restored and features a room devoted to Danish historical artifacts from Junction City's first settlers, a cutaway of the home in the kitchen so visitors can see how buildings were constructed in that time period, and Mary's original furniture in the living room. Next door to the Pitney House is the first jail, built in 1873.

The houses offer exhibits, tours, and occasional recreational and educational events.
