The Sandusky River (Wyandot: saandusti; Shawnee: Potakihiipi ) is a tributary to Lake Erie in north-central Ohio in the United States. It is about 133 miles (214 km) long and flows into Lake Erie at the southwest side of Sandusky Bay. The Sandusky River, like the Maumee River to the west, is home to the annual walleye run in the spring, specifically March–April. The river also receives a run of white bass around the same time in the spring. The numbers of walleye that return to spawn upstream are not as great as those that return to the Maumee River. The Ballville Dam, built on the Sandusky River in Fremont, Ohio, blocked migration for walleye and other fish. As fish can swim farther upstream in the Maumee, they have access to more spawning areas and have developed a larger population than in the Sandusky River. Opponents of the dam projected that its removal would improve access for walleye and other migratory fish to areas upstream and lead to an increase in their population, as has happened on other rivers where dams have been removed. The Ballville Dam was no longer used for power generation or navigation improvements. The city of Fremont undertook a study to explore the options of tearing it down or repairing it. A 2014 study found that removal would have little adverse effect on city conditions and would strongly improve the fisheries. In 2016 voters approved taking down the dam. (Note: The Balville dam was demolished in July 2018). The river's name derives from the Wyandot words saandusti, meaning "water (within water-pools)" or from andusti, meaning "cold water". It was transliterated in various spellings by French and English colonists.

Sandusky Bay is a bay on Lake Erie in northern Ohio, formed at the mouth of the Sandusky River. It was identified as Lac Sandouské on a 1718 French map, with early variations recorded that suggest the name was derived from Native American languages. The Thomas A. Edison Memorial Bridge was constructed across it in the 20th century to connect highways in Erie and Ottawa counties.

The Blue Hole is a fresh water pond and cenote located in Castalia, Erie County, Ohio, in the United States. From the 1920s to 1990 the Blue Hole was a tourist site, attracting 165,000 visitors annually at the height of its popularity, partly because of its location on State Route 269, about 7 miles (11 km) southwest of the Cedar Point amusement park in Sandusky, Ohio. The Blue Hole was known to American Indians and was first recorded in history in 1761.The Blue Hole captured the public’s interest because of its size, about 75 feet (23 m) 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 13.7 m) deep. Water temperature is about 48 °F (9 °C) throughout the year. Floods and droughts have no effect on temperature or water level. The Blue Hole is fed by a passing underground stream which discharges 7 million US gallons (26,000 m3; 5.8×10^6 imp gal) of water daily into Sandusky Bay to the north, feeding into Lake Erie. The water contains lime, soda, magnesia and iron, and because the Blue Hole is anoxic, it cannot naturally sustain fish. The surrounding terrain is developed on limestone bedrock and exhibits karst topography due to dissolution of the limestone by ground water, creating a cenote, a water-filled sinkhole. 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 the Ohio 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.
