6. Lake Mohave, Arizona-Nevada
This Colorado River reservoir is the first of several narrow, twisting manmade lakes that made the list of 11 deadliest lakes in the United States. Created by a 1944 treaty, Lake Mohave is a huge recreational draw in the region, offering better SCUBA diving than most inland bodies of water could ever hope to. The damming process lowered the water temperature and endangered or relocated some species. As with Lake Pleasant, Lake Mohave’s danger lies in boating accidents.
