Lake Purdy Dam
Lake Purdy Dam on the Little Cahaba River was built in 1909 by the Birmingham Water Works. It was raised by 20 feet in 1929, creating the present 1,00 acre Lake Purdy reservoir just above the confluence of the Little Cahaba and the Cahaba River.
The dam is accessed from Lake Purdy Dam Road with gated entrances on Sicard Hollow Road and Cahaba Valley Road. Water released from the reservoir's spillway proceeds into the Cahaba where it is taken up by the Water Works' Cahaba Pumping Station.
