Key Dive Site Facts
Dive Site Overview
Aurora Reservoir's dive area provides a structured environment for divers of all levels, established as a key local training hub. A dedicated SCUBA beach on the eastern shore is roped off, offering a safe zone distinct from other reservoir activities.
A purpose-sunk Cessna 210 wreck serves as a central point for practicing underwater navigation and advanced search and recovery skills. Entry is convenient, accessible via a staircase from the northeastern parking lot or an ADA-compliant ramp. Freshwater conditions support a range of PADI courses, from Open Water to specialty certifications like Altitude Diver.
Depths typically reach up to 6 meters / 21 feet, suitable for foundational skill development. Reservoir operations are seasonal, opening daily from April 1 to October 31, dawn until dusk; night diving is explicitly prohibited.
The emphasis on daylight training aligns with its primary role as a certification and skill refinement location. Infrastructure includes changing areas and permits for grills on cement pads, supporting extended dive day activities.
Best Time to Dive
For the most comfortable diving experience at Aurora Reservoir, plan your visits between April and October, aligning with the site's operational season. Air temperatures during this period average from 8.8°C / 47.8°F in April, climbing to a peak of 23.4°C / 74.1°F in July, then gradually decreasing to 12.7°C / 54.9°F by October. Warmer months generally offer more pleasant surface conditions. Rain is typically minimal, averaging around 1.5-3.3 mm per month during spring and early summer, decreasing later in the season. While water temperatures aren't consistently reported, warmer air temperatures suggest the most favorable in-water conditions occur from late spring through early autumn. Wind speeds are consistently moderate throughout the open season, averaging 23-25 km/h / 14-15 mph, which can influence surface chop but generally won't preclude diving. Planning for these months maximizes comfort and aligns with the reservoir's seasonal accessibility.

Dive Experience & Conditions
Diving in Aurora Reservoir presents typical freshwater lake conditions, which can vary significantly with weather and seasonal turnover. Visibility often shifts, clearer during cooler periods or after extended calm. Divers should prepare for colder water, especially at deeper training depths, necessitating appropriate thermal protection. Maximum depths generally reach 6 meters / 21 feet, making it suitable for entry-level training and skill refinement. As a freshwater environment, the site influences both equipment considerations and the underwater landscape. Surface conditions are generally calm, but moderate winds, averaging around 24 km/h / 15 mph, are common and might create some surface chop. A dedicated SCUBA beach with an accessible ramp facilitates easy shore entries and exits. Such dynamic conditions provide a practical setting for practicing core dive skills, navigation, and search and recovery in real-world, albeit controlled, freshwater conditions.
Dive Difficulty & Safety Guidelines
Understanding the site-specific regulations is crucial for safe diving at Aurora Reservoir. All divers must adhere to the seasonal operating hours of April 1 to October 31, from dawn until dusk; night diving is strictly prohibited. A designated SCUBA dive area is clearly roped off from other reservoir activities, ensuring a dedicated space for training and practice. While no specific inherent hazards are consistently reported beyond typical freshwater diving considerations like variable visibility, prudent divers will always prioritize situational awareness. A daily park entrance fee of approximately $15 per car is required, though there's no additional charge for diving itself. Divers have the option to rent a key for $20 to access a loading zone near the dive area, but this is for gear transport only, not parking. Always carry a dive flag and maintain proper buoyancy control, especially when working around the Cessna wreck.

Recommended Dive Suit
Because recent water temperature readings are not available for Aurora Reservoir, the guidance below is based mainly on current air conditions and seasonal expectations. Current surface air temperatures are roughly 19°C (66°F).
Longer-range forecasts show some uncertainty in upcoming temperature trends. A significant temperature drop is forecast; strongly suggest bringing a backup warmer suit option. A neoprene vest or hood can add flexibility if temperatures feel cooler underwater.
Based on regional estimates and current weather, the likely required exposure protection is a 5mm or thicker wetsuit. Note that local currents and upwellings can alter this. A hood or vest is suggested for sensitive divers due to surface winds. Surface intervals may feel cooler. Many experienced divers adjust their exposure protection depending on the type of dive planned. Divers planning trips later in the week may want to consider bringing a slightly warmer suit.
