Los Angeles River
The city of Los Angeles rose beside the Los Angeles River, inland at the site of the old Spanish settlement. In 1889, San Pedro Bay, the place where the river flows into, was chosen as the city harbor. A series of railroads were needed to connect the city with the port. The most logical route was beside the river, since that was the smoothest land. With the railroads came industry, which rose up all along the lower Los Angeles River. With its disastrous flood history, and the fact that it was too shallow for boats, the river was finally forced into a concrete channel beginning in 1938.
