Dive Site Characteristics
Dive Site Overview
Emerging from its industrial past, Three Oaks Recreation Area has been thoughtfully repurposed into a freshwater dive site. This substantial 300-acre quarry now hosts a dedicated dive zone, roughly three acres in size, conveniently located just east of the Marina.
Divers can expect straightforward water access, available either directly from the shore or via a floating dock. This setup makes the site particularly amenable for both initial dive training and ongoing recreational practice. For structured skill development, the designated area includes three distinct training platforms.
These are spaced approximately 30 meters (100 ft) apart, each consistently positioned at a depth of 7.6 meters (25 ft), providing clear reference points for instruction and buoyancy drills. Beyond these training structures, the dive area gradually slopes downwards, eventually reaching a maximum reported depth of 13.7 meters (45 ft).
This former quarry environment offers an exploration of rock formations and a relatively clear bottom, a contrast to typical lake beds. The site's character, defined by its geological history, creates a unique underwater landscape suitable for divers of various experience levels seeking accessible inland diving.
Its design supports typical beach and lake diving methodologies, providing a controlled yet engaging environment.
Best Time to Dive
Planning your dive around the climate can significantly enhance the experience at Three Oaks Recreation Area. The period from May through October generally offers the most favorable conditions, with average air temperatures ranging from 15.2°C (59.4°F) in May to 12.9°C (55.2°F) in October. Rainfall tends to be moderate during these months, with July seeing the highest average at 4.43 mm, while September and October are relatively drier, averaging around 2 mm. Although February shows an "Excellent" dive score, this is likely due to winter diving appeal; surface air temperatures average -1.1°C (30.0°F) in February, necessitating specialized cold-water gear. For milder conditions and general comfort, late spring to early autumn is often preferred.
