The Spring River is a 57-mile (92 km) long river which flows through the U.S. states of Missouri and Arkansas. It consists of two branches, the South Fork of the Spring River and the Spring River proper. The South Fork of the Spring River starts in Howell County, Missouri and flows south through Fulton and Sharp counties in Arkansas. The South Fork of the Spring River joins the Spring River proper near the town of Hardy, Arkansas. The South Fork is a quiet stream with gravel bars that are ideal for camping. The Spring River proper begins where Mammoth Spring and Warm Fork of the Spring River merge at Mammoth Spring State Park in Mammoth Spring, Arkansas. Mammoth Spring is the outlet of an underground river that runs from Missouri into Arkansas. Over 9.78 million US gallons (37,000 m3) per hour flow out of the massive spring and forms the Spring River. Being predominantly spring fed with water averaging 58 °F (14 °C), the river is kept cool during warmer months and is suitable trout habitat for several miles.
The South Fork of the Spring River is a tributary of the Spring River, roughly 75 mi (121 km) long, in southern Missouri and northern Arkansas. The river flows through the Salem Plateau of the Ozarks and it is part of the Spring River Tributaries Watershed. The South Fork rises in Howell County northeast of the unincorporated community of South Fork, Missouri and southwest of West Plains. The river flows generally southeast from Howell County through Fulton County before joining with the Spring River in Sharp County outside of Hardy. It flows through eastern Ozark hill country, pasture land, and oak-hickory forests. It is a gravel bottom stream with some silty areas that contains a good smallmouth bass and shadow bass population. Catfish are also stocked annually.
The Myatt Creek is a stream in northeastern Fulton County, Arkansas and southeastern Howell County, Missouri. It flows southeasterly for about 20 miles then enters the Spring River near the town of Hardy. It is a fairly shallow stream with few pools over 5 feet deep. The bottom is mostly gravel and sand. The water is clear. It contains good populations of smallmouth and spotted bass, and shadow bass. Most of the smallmouth will be 10- to 12-inches in length but there are 20-inch fish in this creek.
Myatt Creek has the name of a pioneer settler who is said to be buried along its course.
