The Cedar River is a 338-mile-long (544 km) river in Minnesota and Iowa. It is a tributary of the Iowa River, which flows to the Mississippi River. The Cedar River takes its name from the red cedar trees growing there, and was originally called the Red Cedar River by the Meskwaki. The first Mississippi steamboat reached Cedar Rapids, Iowa in 1844, and during the next decade, the Red Cedar was an important commercial waterway. The surrounding region is known officially as the Cedar River Valley, though it is more commonly referred to simply as the Cedar Valley. The stream is young geologically, and only in places where the glacial material has been removed is the underlying bedrock exposed.

It is normally transcribed without an apostrophe.
The Little Pigeon River is a river located entirely within Sevier County, Tennessee.

The Root River flows for 80 miles (130 km) through the Driftless Area of southeastern Minnesota and is a tributary of the Upper Mississippi River. The Root River is formed by three branches, the North, South and Middle branches of the Root River and the South Fork Root River. It is an excellent river for canoeing and fishing. The gentle to moderate flowing river drops an average of 3.4 ft/mile from Chatfield, Minnesota, to its pour point in the Mississippi River into Navigation Pool 7 just south of La Crosse, Wisconsin and east of Hokah, Minnesota.
The Bois de Sioux River drains Lake Traverse, the southernmost body of water in the Hudson Bay watershed of North America.

It flows for most of its length as two parallel streams in Iowa, the East Nishnabotna River and the West Nishnabotna River. The east and west branches are each about 120 miles (190 km) long; from their confluence the Nishnabotna flows approximately another 16 miles (26 km). Several sections of the rivers' courses have been straightened and heavily channelized.
The Raccoon River is a 30.8-mile-long (49.6 km) tributary of the Des Moines River in central Iowa in the United States. As measured using the longest of its three forks, its length increases to 226 miles (364 km). Via the Des Moines River, it is part of the watershed of the Mississippi River. The river runs through an intensely cultivated area of croplands and livestock farming, receiving Tile drainage from slow-draining rich natural bottomland.
Miesville Ravine Park Reserve is a Dakota County park near the town of Miesville, Minnesota, United States. It preserves over 1,600 acres (6 km2) of biologically diverse land in the Cannon River valley. Most of the park is wooded with mature oak, maple, cottonwood, willow, red cedar, and white pine.

Trophy-sized trout used to be found in the river often but not much anymore.
The Whitewater River is a 16.6-mile-long (26.7 km) tributary of the Upper Mississippi River which flows through the Driftless Area of Minnesota, reaching its mouth in Wabasha County at the community of Weaver opposite Buffalo, Wisconsin. The nearest towns are Altura, Saint Charles, and Elba. The region hosts endangered native dry oak savannas, semiforested areas that seem to have been dependent on fire for their well-being.
The Clearwater River is in the northwestern United States, in north central Idaho.
