Francis Canyon (Mouth) is a freshwater dive site featuring underwater canyon walls and rocky crevices. Access is exclusively by boat. Divers should be prepared for challenging conditions, including low visibility that can drop to 3 metres and significant thermoclines. Water temperatures are cold, measuring approximately 3 to 4 degrees Celsius in early April, with marked temperature drops occurring below 12 metres. Due to the cold water, low visibility, and depth, this site is suited for advanced divers. Facilities available at the location include parking, toilets, showers, changing rooms, and a rinse station. Boat charters and guided tours are available to assist with site access.

Navajo Dam Spillway is a freshwater site offering shore access near the concrete spillway. The topography features two distinct underwater ledges that drop off into deeper water as levels rise. Divers and snorkellers can explore depths reaching 30 metres, though conditions vary with visibility ranging from 3 to 12 metres. A thermocline typically occurs at 11 metres, where temperatures drop from the low 80s°F at the surface to the low 60s°F. Winter temperatures are significantly colder, reaching the 40s°F. Due to the depth and potential for low visibility, this site is best suited for intermediate divers. Facilities at the location include parking, toilets, and showers.
