About this postcard

The aerating water wheel stands at the Blue Hole, a spring-fed pool near Castalia, Ohio, with flowering shrubs and dense green foliage behind it. A rustic sign identifies the wheel. The spring discharges about seven million gallons a day, enough for a city of 75,000, but the water is described as "dead-devoid of oxygen." The wheel lifts the water so it falls over a cascade and picks up oxygen, making the pool habitable for fish. The Blue Hole was a roadside stop six miles west of Sandusky, open day and night, and promotional text placed it in "Ohio's Lake Erie Vacationland." Castalia's cold springs also supported fish hatchery work in the area.

33—Aerating Water Wheel at Blue Hole, Castalia, Ohio In Ohio's Lake Erie Vacationland --- THE AERATING WATER WHEEL AT THE BLUE HOLE, CASTALIA, OHIO. The volume of water flowing from this marvelous spring is seven million gallons daily, sufficient to supply a city of 75,000 population. The water is dead-devoid of oxygen—and fish will not live in the water emitted from this spring until it is aerated by passing over giant waterfalls. The Blue Hole is located six miles west of Sandusky, Ohio, on State Route 101 and Federal Route 6. Open day and night. E. B. ACKLEY, SANDUSKY, OHIO GENUINE CURTEICH-CHICAGO "C.T.
