Dams
Five dams on the Dead River are associated with hydroelectric projects, listed in downstream order: Silver Lake Dam, Hoist Dam, McClure Dam, Forestville Dam, and Tourist Park Dam. The first three are owned by the Upper Peninsula Power Company, and the last two are owned by the Marquette Board of Light and Power.[8][4]
On May 14, 2003, the earthen Silver Lake Dam burst, cause by the failure of a fuse plug that had been installed the previous year. Nine billion gallons of water were released, prompting the evacuation of 1,872 people. The Hoist, McClure, and Forestville dams were damaged, and the Tourist Park Dam was breached. No deaths or major injuries occurred; damage was estimated at $100 million.[9] The Silver Lake and Tourist Park dams were later rebuilt.[8]
Waterfalls

Several waterfalls occur on the Dead River, including ten in an approximately one mile (1.6 km) stretch of a gorge on the river near the Forestville Basin, which feature exposures of Archean bedrock, specifically the Lighthouse Point member of Mona Schist.[10][11]
Name
Historically, its name is derived from the Ojibwe Gaa-waakwimiigong-neyaashi-ziibi (recorded as "Kah way komi gong nay aw shay Sibi", meaning "Peninsula by the Roads to the Land of the Dead River") or Ne-waakwimiinaang (meaning "by the Peninsula for Road to the Land of the Dead"), both referencing its mouth being near Presque Isle Point, a cape on Lake Superior. Another former name of the river as prescribed by French missionaries was Noquemanon (or "No-kay-ma-non"), named for the Noquet Indians who historically inhabited the area, and meaning "the berry patch of the Noquet".[12] Additionally, earlier maps record this river either in French as "Rivière des Morts", "Rivière du Mort", or "Rivière au Paresseux", or in English as "Deadman's River". The current name for this river in Ojibwe is either Giiwe-gamigong-neyaashi-ziibi (Return-by-shore Peninsula River) or Niboowaagaming ("At the Death's Shores").
