Book excerpt: Chinese pioneers in the Sacramento River Delta were the vital factor in reclaiming land and made significant contributions to Californias agricultural industry from farming to canning. Since the 1860s, Chinese were already settled in the delta and created Chinatowns in and between the two towns of Freeport in the north and Rio Vista in the south. One of the towns, Locke, was unique in that it was built by the Chinese and was inhabited almost exclusively by the Chinese during the first half of the 1900s. The town of Locke represents the last remaining legacy of the Chinese pioneers who settled in the delta.
