Moses Lake History

Moses Lake was originally known as Neppel. It was later renamed in honor of Chief Moses, chief of the Native Americans called Sinkiuse-Columbia, who had inhabited the area before the arrival of the white settlers. Chief Moses was arrested for the 1878 murder of a white couple whose bodies were found near Rattlesnake Springs. He was tried for murder but found innocent. After he was freed, Chief Moses met with President Rutherford B. Hayes and surrendered control of Columbia basin to the United States Government. The area was then opened up for homesteading. The earliest white settlers were mostly farmers.
