There is no record of when the last Native American camp ceased to exist in the Folsom Lake region. Many historians note that by 1853, most of the Native American population had dispersed, move south, died in conflicts with immigrant settlers, or died of disease. But there is no doubt that there was a thriving Native American population and culture along the north and south forks of the American River. Where Native Americans once ground acorns, skinned deer, or fashioned tools from local rocks, Folsom Lake visitors now fish, hike, ride horses, bikes, and have picnics.
It can be a difficult task to locate the faint outlines of the Negro Hill Ditch which is usually under water at Folsom Lake. But when the lake is low enough it’s possible to find the old grade and structures associated with the historic water canal that ran from east of Salmon Falls down to Negro Hill and Massachusetts Flat. In the autumn of 2016 I was able to complete my goal of walking along most of the Negro Hill Ditch.
