Eighth Avenue South Reservoir is a man-made masonry reservoir in Nashville, Tennessee. The reservoir was built on Kirkpatrick's Hill which was the former site of Fort Casino: a Union Army fort in the American Civil War. Completed in 1889, it ruptured in 1912 causing much property damage, and was repaired in 1914. In 1978, it was listed on the National Register of Historic Places listings in Davidson County, Tennessee (NRHP). The reservoir is the largest and oldest working reservoir supplying water to the city of Nashville, and remains in use as of 2022[update].
