Nevada allows seaplane landings on most of its water bodies, without restrictions. There are a few large lakes in the northern part of the state and of course, the Colorado River and its impoundments. Check for seaplane operating restrictions on the Colorado River in the Water Landing Directory (seaplanes are not allowed to taxi into the National Park Services marinas under power).
The elevation in the southern corner of the state is around 550 feet but with the summer density altitude the effective elevation can be above 3,000 feet. Central Nevada lake elevation is around 4,500 feet, with a summer density altitude of more than 7,000 feet.
Seaplane recreation is enjoyed in Nevada by many pilots from the southwestern states.
