Dive Site Characteristics
Dive Site Overview
Circleville Twin Quarries presents a unique proposition for inland diving, distinguished by its dual nature—two distinct quarry basins, each with individual characteristics. One quarry typically offers improved clarity, attracting more divers, while its counterpart, though often less clear, provides a more secluded diving experience.
For those undertaking initial certifications or refining buoyancy, this site is highly advantageous. Submerged training platforms are a practical feature, aiding in skill development in a controlled environment.
Additionally, various artifacts like buses, boats, and even planes have been strategically placed, transforming the quarry floor into an intriguing underwater playground. Located in Circleville, Ohio, the site serves as a full-service dive center, supplying air fills, rental gear, and shop amenities, enhancing convenience for visitors.
With maximum depths generally around 18-20 ft (5-6 m), it's primarily a shallow water destination suitable for diverse skill levels, particularly new open water students.
Best Time to Dive
Optimal diving conditions at Circleville Twin Quarries generally align with warmer months, though the quarry is open year-round. Air temperatures rise from 12.7°C (55°F) in April to a peak of 24.4°C (76°F) in July, providing comfortable surface conditions for divers. These shallower quarries tend to warm up faster than deeper bodies of water, making spring and early summer particularly inviting. Rainfall patterns, averaging 3-4 mm per month during these peak seasons, usually don't significantly impact visibility. While specific water temperature data isn't consistently reported, the site's shallow nature implies quicker warming during the summer, offering pleasant water conditions for extended periods. Dive scores indicate "Good" conditions from February through November, suggesting ample opportunities throughout much of the year, with less favorable but still "Good" scores in winter months.

Dive Experience & Conditions
Navigating the freshwater environment of Circleville Twin Quarries, divers won't encounter significant currents, allowing for relaxed underwater exploration. Visibility, however, varies notably between the two quarries. One basin often presents clearer conditions, making it a preferred choice for many, while the other can be murkier but offers a more solitary diving experience. Since the quarries are shallow, generally within recreational depth limits, they warm up considerably faster than deeper sites, extending the comfortable dive season. Divers can expect a max depth around 18-20 ft (5-6 m), making it an accessible site for new Open Water students practicing fundamental skills. The terrain consists primarily of quarry floor, with various submerged structures providing focal points.
Dive Difficulty & Safety Guidelines
Approaching Circleville Twin Quarries requires adherence to standard safe diving practices, as with any dive site. The shallow nature of the quarries, typically within recreational depth limits, makes them especially suitable for new divers undergoing certification checkouts and those seeking to refine their buoyancy skills. Training platforms are present to facilitate skill practice in a controlled setting. It's always prudent for divers, regardless of experience, to consult with the onsite dive professionals about current conditions before entering the water. Utilizing the available facilities, such as picnic shelters and changing rooms, ensures a more comfortable and organized dive day.
