Dive Site Overview
The dive site known as Culverts, part of Utah's Sand Hollow Reservoir, offers an unusual underwater landscape shaped by human ingenuity. Divers explore a series of large drainage culverts forming a dedicated buoyancy course, alongside other submerged features like a twin-engine Cessna and a VW pop-up camper van.
These artificial components provide intricate navigation challenges and shelter for local aquatic life. The site is part of Sand Hollow State Park, situated at an elevation over 3000 ft (914 m), which necessitates specific altitude diving protocols. Guidelines are in place to ensure a safe and engaging experience, with a black buoy marking the entry point and lines guiding explorers to the main attractions. Maximum depth here reaches 5 m (18 ft), making it accessible for recreational divers.
Best Time to Dive
Planning your trip to Culverts often hinges on surface conditions impacting the overall experience. The region experiences warmer air temperatures during summer months, with average highs ranging from 27.2°C (81°F) in June to 29.1°C (84°F) in August. This period typically sees lower wave heights, averaging 0.6-0.9 meters (2-3 ft), which contributes to calmer surface conditions. Rainfall remains moderate year-round, generally between 3-5 mm (0.1-0.2 inches) per month, minimizing its impact on dive plans. While specific water temperature data isn't consistently reported for this inland site, warmer air implies more comfortable surface intervals. Dive scores indicate 'Good' conditions for diving from February through October, suggesting a broad window for enjoyable excursions.

Dive Experience & Conditions
Diving at Culverts means navigating a freshwater lake, which presents different dynamics than ocean dives. The primary depth reaches 5 m (18 ft), making it a relatively shallow experience focused on skill-building and exploration of artificial structures. Visibility can vary, but the lake environment often allows for clear views of the submerged Cessna, VW camper, and the namesake culverts. Given its altitude of over 3000 ft (914 m), divers must account for specific pressure changes, impacting dive planning and gas consumption. Currents are generally minimal within the protected confines of the reservoir, allowing for relaxed buoyancy practice. The site's artificial elements are designed to enhance learning, offering multiple hiding places and swim-throughs formed by the enormous building blocks.
Dive Difficulty & Safety Guidelines
An expert tip for diving Culverts involves careful preparation for altitude diving protocols. Operating at over 3000 ft (914 m) requires adjustments to dive tables or computers to prevent decompression sickness. Divers should maintain excellent buoyancy control, especially when navigating the intricate structures of the buoyancy course and the interior of the culverts. Adhering to responsible interaction guidelines with the environment and structures is essential. A dive flag and a surface marker buoy are practical safety tools, enhancing visibility to surface users. Entry to the site is typically from the shore, providing direct access to the marked buoy and guided lines. It's advisable to check local park fees and dive shack operating hours, as services may be limited to weekends.
