Original Note:
The LA River is a real, naturally occurring river. It was lined with concrete by the Army Corps of Engineers in the early 20th century in order to prevent seasonal flooding. It has been flowing continuously since record keeping began in 1929, almost 100 years. https://en.wikipedia.org/wiki/Los_Angeles_River?wprov=sfti1
