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.

Lakeside Lodge Marina Protected Cove is a freshwater snorkel site located in the United States near Fremont Lake. This sheltered area near the marina docks provides protection from frequent afternoon winds and offers relatively shallow water. The site features an artificial reef composed of sunken trees, which are often covered in lost fishing lures. Entry is possible from both the shore and by boat. Due to the high-altitude location, water temperatures are very cold, ranging from 4°C to 21°C depending on the season and depth. Divers and snorkellers should be aware of boat traffic, cold water risks, and potential entanglement hazards. Exposure protection is strongly recommended.
