Alcona Dam is a hydro-electric dam on the Au Sable River in Michigan .
The Au Sable River in Michigan , United States runs approximately 138 miles ( 222 km ) through the northern Lower Peninsula , through the towns of Grayling and Mio , and enters Lake Huron at Au Sable . It is considered one of the best brown trout fisheries east of the Rockies and has been designated a blue ribbon trout stream by the Michigan Department of Natural Resources . In French , au sable literally means at the sand . A 1795 map calls it the Beauais River .
The Kalamazoo River is a river in the U.S. state of Michigan . The river is 130 miles ( 210 km ) long from the junction of its North and South branches to its mouth at Lake Michigan , with a total length extending to 178 miles ( 286 km ) when one includes the South Branch . The river 's watershed drains an area of approximately 2,020 square miles ( 5,200 km2 ) and drains portions of eight counties in southwest Michigan : Allegan , Barry , Eaton , Van Buren , Kalamazoo , Calhoun , Jackson , Hillsdale , Kent and Ottawa . The river has a median flow of 1,863 cubic feet per second ( 52.8 m3/s ) at New Richmond , upstream from its mouth at Saugatuck . The North and South Branches of the Kalamazoo River originate within a few miles of each other . The South Branch begins near North Adams in Moscow Township in northeastern Hillsdale County and flows north and west through Homer before joining the North Branch at the forks of the Kalamazoo in Albion . The North Branch begins near Farewell and Pine Hills lakes in southern Jackson County and flows north and west through Concord before reaching Albion in Calhoun County . It then flows through Kalamazoo and Allegan counties . After Albion , the Kalamazoo flows mostly westward through Marshall , Battle Creek , Augusta , Galesburg , Comstock , and Kalamazoo . From Kalamazoo , the river flows mostly north until just before it reaches Plainwell and then flows northwest through Otsego , Allegan , Saugatuck and then into Lake Michigan . Some of the larger tributaries of the Kalamazoo are Rice Creek , Wilder Creek , Wabascon Creek , Battle Creek River , Augusta Creek , Portage Creek , Gun River , Swan Creek , and Rabbit River .
Cooke Dam is a hydro-electric dam on the Au Sable River in Michigan . It was listed on the National Register of Historic Places in 1996 as the Cooke Hydroelectric Plant .
Croton Dam ( or Croton Hydroelectric Plant ) is an earth-filled embankment dam and powerplant complex on the Muskegon River in Croton Township , Newaygo County , Michigan . It was built in 1907 under the direction of William D. Fargo by the Grand Rapids - Muskegon Power Company , a predecessor of Consumers Energy . The 40-foot-high ( 12 m ) dam impounds 7.2 billion U.S. gallons ( 6 billion imp . gal/27 billion L ) of water in its 1,209-acre ( 489 ha ) reservoir and is capable of producing 8,850 kilowatts at peak outflow . It was listed on the National Register of Historic Places in 1979 .
Muskegon River is a river in the western portion of the lower peninsula of the U.S. state of Michigan . The river has its headwaters in Houghton Lake in Roscommon County , flowing out of the North Bay into neighboring Missaukee County . From there it flows mostly southwest to Muskegon , Michigan , where it empties into Muskegon Lake . Muskegon Lake is connected to Lake Michigan via a mile-long channel . The river has several major branches , such as the Hersey River , Cedar Creek and Little Muskegon River . The main stream is 216 miles ( 348 km ) long and drains an area of 2,350 square miles ( 6,100 km2 ) . In September 2002 an often cited article , National Geographic raised concerns about a controversial deal made with Nestle Waters North America giving them permission to bottle up to 210 million gallons ( about 800 million liters ) a year from an aquifer north of Grand Rapids , Michigan that recharges the Muskegon River .
Five Channels Dam is a hydro-electric dam on the Au Sable River in Michigan .
Foote Dam is a hydro-electric dam on the Au Sable River in Michigan .
Hardy Dam ( or Hardy Hydroelectric Plant ) is an earth-filled embankment dam and powerplant complex on the Muskegon River in Big Prairie Township , Newaygo County , Michigan . At the time of its completion , it was the largest earthen dam in North America east of the Mississippi . Its impoundment forms a lake with over 50 miles of shoreline . The dam impounds a reservoir with a surface area of 4,000 acres ( 1,618 ha ) and its power plant has an installed capacity of 31.5 MW .
The Manistee River in the U.S. state of Michigan , runs 190 miles ( 310 km ) through the northwestern Lower Peninsula ; it now passes through the contemporary villages of Sharon , Smithville , and Mesick , entering Lake Michigan at Manistee . It is considered , like the nearby Au Sable River , to be one of the best trout fisheries east of the Rockies . The river rises in the sand hills in southeastern Antrim County , on the border with Otsego County , about 6 miles ( 10 km ) southeast of the town of Alba . These deep glacial sands provide it with a remarkably stable flow of clean cold water year round , making it a popular river for fishing as well as canoeing . Over the course of its length , it drops in elevation from around 1,250 to 579 feet ( 381 to 176 m ) , with an average stream gradient of about 2.9 feet per mile ( 55 cm/km ) .
Tippy Dam or Tippy Hydro was built 1918 and is a hydroelectric dam operated by Consumers Energy . The original name of the dam was Junction Hydro , but it was renamed to honor a Consumers board of directors member , Charles W. Tippy . The dam spans the Manistee River about 170 miles from its headwaters which include Manistee Lake , on the river 's way to Lake Michigan .
The Grand River is a river in the southwestern portion of the southern peninsula of Michigan , United States , that flows into Lake Michigan 's southeastern shore . It is the longest river in the U.S. state of Michigan , running 252 miles ( 406 km ) from its headwaters in Hillsdale County on the southern border north to Lansing and west to its mouth on the Lake at Grand Haven . Native Americans who lived along the river before the arrival of the French and British called the river O-wash-ta-nong , meaning Far-away-water ' , because of its length . The so named Grand Rapids , located in what is today the namesake city , were a mile-long , 300 yards wide and 10-15 feet-tall rapids for which the river was famous . These were submerged following the construction of numerous dams , starting in 1835 , and flooding of areas behind the dams . The river has not had any rapids for nearly a century .
