Before: The Buttonbush Park riparian corridor consisted of fine sediment substrate, Himalayan blackberry and thick understory, and only partially inundated at ~5,000 cubic feet per second. To create suitable habitat under the current, regulated flow regime, thick vegetation was cleared and side channels were excavated by as much as 8 feet. © Cramer Fish Sciences
