Upper Boat Ramp is a freshwater dive site located within the Fremont Lake Campground in the United States. Divers enter from the shore to explore an underwater terrain composed of cobble and gravel that transitions into a steep shelf. The site reaches depths of up to 40 metres. Conditions are generally mild, though divers should be aware of a thermocline between 8 and 9 metres where water temperatures drop significantly. Cold water is a primary hazard at this location. The site is suitable for beginners and supports night diving, with typical dives lasting around 45 minutes. Facilities including parking and toilets are available on-site.

Moosehead Bay is a freshwater pinnacle site featuring massive, car-sized granite boulders that form dramatic canyons and crevices. Located at the northern end of the lake, the site offers depths ranging from 5 to 30 metres, with an average depth of 10 metres. Visibility is generally good, between 15 and 25 metres. Access is by boat only. The water is extremely cold, with surface temperatures between 13 and 21°C in summer and a significant thermocline dropping to 4.4°C. Due to the risk of cold-water shock and hypothermia, this site is suited for intermediate snorkelers and divers prepared for cold-water conditions.
