History (Wikipedia):

"TheBlue Holeis a fresh waterpondandcenotelocated inCastalia,Erie County,Ohio, in the United States. From the 1920s to 1990 the Blue Hole was atourist site, attracting 165,000 visitors annually at the height of its popularity, partly because of its location onState Route 269, about 7 miles (11km) southwest of theCedar Pointamusement park inSandusky, Ohio.

The Blue Hole was known toNative Americansand its first known recorded description was in 1760.[1]

The Blue Hole captured the public’s interest because of its size, about 75 feet (23m) in diameter, clarity, vibrant blue hue, and enigmatic "bottomless" appearance. Contrary to prevalent belief, the depth of the Blue Hole is not unknown, but has been sounded and found to be about forty-three to forty-five feet (13.1 to 13.7m) deep. Water temperature is about 48°F (9°C) throughout the year.Floodsanddroughtshave no effect on temperature or water level. The Blue Hole is fed by a passing undergroundstreamwhich discharges 7million US gallons (26,000m3; 5.8×106impgal) of water daily intoSandusky Bayto the north, feeding intoLake Erie. The water containslime,soda,magnesiaandiron, and because the Blue Hole isanoxic, it cannot naturally sustain fish. The surroundingterrainis developed onlimestonebedrockand exhibitskarst topographydue to dissolution of the limestone byground water, creating a cenote, a water-filledsinkhole.

Several similar cenotes are known to local residents. The Blue Hole that once was a tourist attraction is now off limits to the public. It is located on the grounds of Castalia Trout Club, a privately owned fishing club. It is to be distinguished from another cenote, similar in size and eerie bluish-green color, owned by the Castalia State Fish Hatchery and operated by theOhio Department of Natural Resources, Division of Wildlife, which is open for public viewing and which has grown in popularity since the closure of the Blue Hole in the late 1990s.[2]"
