The Nolichucky River rises as the
confluence of the
North Toe River and the
Cane River near the community of
Huntdale, North Carolina. The stream succeeds the North Toe as the boundary between
Yancey County and
Mitchell County, North Carolina. Trending roughly westward, it flows along the northern base of Flattop Mountain. The gorge is especially steep on its north side. Geologically, the area is predominantly underlain by
metamorphic rock of
Precambrian age. from the east, as seen from the
Appalachian Trail just south of Erwin The river then enters
Unicoi County, Tennessee, as it drops through a whitewater gorge, flowing between the ranges of the
Bald Mountains (to the south) and the
Unaka Mountains (to the north). Turning northwest, the stream is bridged by the
Appalachian Trail and by
U.S. Highway 19W southwest of
Erwin, Tennessee. Near Erwin, two
tributary streams, South Indian Creek and North Indian Creek, join the Nolichucky River. Turning more to the north, the stream is paralleled for several miles by
State Route 81, (which is also concurrent with
Tennessee State Route 107 for several miles) crossing into
Washington County. The river cuts between several mountains at this point, including Rich Mountain to the south and Buffalo Mountain to the north. Shortly after entering Washington County, the river makes a horseshoe bend near
Embreeville, where it is bridged by SR 81 and SR 107 for the first time. At the northeastern end of Embreeville Mountain, the stream emerges from a large
gap and turning west-southwest is bridged by SR 81 again. Here it exits the
Blue Ridge Mountains and enters the
Ridge and Valley province, which is underlain primarily by
sedimentary rock of the Lower
Paleozoic Era. The river then continues west-southwest for several miles, paralleled by SR 107. The river leaves the roadside near
Mt. Carmel. From there it flows northwest over a winding course to
David Crockett Birthplace State Park near the Washington County–
Greene County line. Many tributary creeks join the river in Washington and Greene counties. At the county line, one of the larger tributaries, Big Limestone Creek, joins the river.
State Route 351 crosses the river west of Crockett's birthplace. The river then flows southwestward, following the trends of the Ridge and Valley province's underlying geology. Bridged by SR 107 again just east of
Tusculum, the stream continues southwestward, later bridged by
State Route 350 just above an impoundment caused by
Nolichucky Dam. This dam was constructed as a
hydroelectric project by the former Tennessee Electric Power Company in 1912. The dam was sold to the
Tennessee Valley Authority (TVA) in 1939, when the agency was established by the
Franklin D. Roosevelt administration during the
Great Depression. The TVA continued to operate the dam for electrical power purposes until the 1970s. The degree of
siltation of the
reservoir, called
Davy Crockett Lake, had made continued efforts to operate the facility for hydroelectric purposes impracticable. The agency retired the dam as a power source but continues to maintain it and to use it for flood control and recreational purposes. Just west of the dam, the river crosses
State Route 70 and SR 107 for a third and final time. Continuing almost due west, the river is bridged by
U.S. Highway 321. Just before reaching the Greene County–
Cocke County line, the river is bridged by
State Route 340. Just past this point, the river becomes the border between the counties. A few miles below this point it is bridged by Knob Creek Road. South of
Interstate 81, Greene, Cocke, and
Hamblen counties come to a point at a bend in river, where Lick Creek joins the river. From this point on, the meandering stream forms the Hamblen County–Cocke County line. The confluence of the Nolichucky with the
French Broad River occurs in the upstream portion of the
Douglas Lake impoundment, caused by
Douglas Dam, a
World War II-era TVA project located downstream along the French Broad. The mouth of the Nolichucky lies near the point where Hamblen, Cocke, and
Jefferson counties meet. Near the mouth is the Rankin Wildlife Management Area, a reserve operated by the
Tennessee Wildlife Resources Agency. ==History==
