Inglis Dam was originally completed across Florida's Withlacoochee River (south) in 1909 for the purpose of hydroelectric power generation by the then Florida Power Corporation. It produced power up until 1965. http://inglishydropower.com/History.html
Inglis Dam blocks access by Florida manatees and various marine or estuarine-type fishes to the Rainbow River (a.k.a. Blue Run) and its headwater Rainbow Springs along with the upper reaches of the Withlacoochee River (south). No historical records have been found that describe the existence of any native striped bass population in the Withlacoochee River (south) prior to the construction of the Inglis Dam.
Inglis Main Spillway
Upstream is Lake Rousseau (3,400 acre pool at elevation [elv.] 27.5 feet above sea level).
Downstream is the "Lower" Withlacoochee River (tailrace elv. 2 feet BELOW sea level to 5 feet above sea level).
Fall (head) at the dam averages 25 feet and was used for hydroelectric power generation up until 1965.
