If you're diving near Phoenix, Lake Pleasant is where you start, and for a lot of divers, it's where you keep coming back. One lake, every certification level, from first checkout dives to serious technical depth.
Located off the Carefree Highway in Peoria, about 35 miles northwest of Phoenix, Lake Pleasant is one of the most accessible and versatile dive destinations in the Southwest. The lake covers roughly 10,000 acres and reaches depths of over 260 feet near the dam. Finishing your Open Water certification, working on specialty skills, or pushing into technical depth, there's a site here for every level.
Three main shore sites cover every certification level, plus a piece of Arizona history for technical divers, all in one lake.
One of the most popular shore entry points at the lake. The bottom slopes gradually from shallow water down to significant depth, and the entry is forgiving enough for newer divers to get comfortable before dropping deeper. It's a go-to for training dives and skill work, and experienced divers use it regularly to warm up before pushing further out.
A shore dive with character. The bottom slopes gently and the site has picked up some interesting finds over the years, so it's the kind of dive where you never quite know what you'll come across. Visibility varies, but on good days it opens up and rewards divers who slow down and look around.
The most beginner-friendly entry point on the lake. The bottom is a gentle slope of silt and small rocks, max depth tops out around 30 feet, and the protected location keeps conditions manageable. If you're finishing Open Water checkout dives or getting a student comfortable in open water for the first time, this is the site, and it's close enough to depth to be useful for skill work before moving somewhere more demanding.
For technical divers, the Old Waddell Dam is the draw. Built in 1927 and submerged when the New Waddell Dam came online in 1994, it's one of the most unique dive structures in Arizona and reaches depths that put it firmly in technical territory. Recreational and technical divers both use this site, and it adds a layer of history to the lake that most freshwater dive destinations don't have.
Lake Pleasant runs the full range of the Arizona desert across a year, and what you wear matters.
Visibility at Lake Pleasant is honest freshwater visibility, typically 5 to 15 feet, with spring offering the best conditions and sometimes reaching 25 to 30 feet. Winter months with less boat traffic tend to be cleaner as well. Summer brings more activity on the surface and can stir things up. Going deeper improves clarity in some conditions, but also means darker water, so a good dive light is worth carrying on any dive past 30 feet.
This isn't a reef dive. It's a desert lake with its own character, submerged terrain, and wildlife that surprises you when you slow down and look. The lake holds a healthy mix of freshwater species.
Lake Pleasant is where a lot of Arizona divers earn their Open Water card, and the reason is simple: the three main shore dive sites cover every certification level without making anyone drive to a second location. Desert Tortoise handles beginners. Sunset Ridge and Vista Point give newer divers room to build skills and confidence. The Old Waddell Dam gives technical divers a real objective with depth and history behind it.
Most divers opt for shore diving here rather than boat diving. It's laid back, the entry points are easy to manage, and it's simple to log multiple dives in a single day without a lot of logistics in between. For Dive Arizona students, this is home water. We run training dives here regularly, and it's the first place we take new divers after the pool.

Yes. Desert Tortoise maxes out around 30 feet with a gentle slope and protected entry, making it one of the best Open Water training sites in Arizona. Sunset Ridge also works well for newer divers building comfort and skills before moving to deeper water.
The lake reaches over 260 feet near the New Waddell Dam, making it suitable for both recreational and technical diving. Most shore dive sites at Desert Tortoise, Sunset Ridge, and Vista Point range from shallow entry down to recreational depths.
Surface temperatures range from the upper 40s in January to around 84 to 90 degrees Fahrenheit in July and August. A 3mm suit works in summer, a 5mm to 7mm suit in fall and spring, and a drysuit is recommended for winter dives, especially at depth.
Catfish, largemouth bass, white bass, bluegill, carp, and crayfish are common. The Old Waddell Dam adds historical interest for more advanced divers, and submerged terrain including rock walls and canyon features gives the lake more structure than most freshwater dive sites.
Lake Pleasant Regional Park is located in Peoria, Arizona, about 35 miles northwest of Phoenix off the Carefree Highway. It's an easy day trip from anywhere in the Valley.
