Rivanna River

The Rivanna River is a tributary of the James River, about 50 mi (80 km) long, in central Virginia in the United States. The Rivanna's tributaries originate in the Blue Ridge Mountains; via the James River, it is part of the watershed of Chesapeake Bay.

According to the Geographic Names Information System, the Rivanna has also been known as "Mountain Falls Creek" and "River Anna."

History

Monacan Indians were the inhabitants of the Rivanna valley at the time of first contact by Europeans. The locations of several sites from the period are known, and some have been explored by archaeologists. One in particular, a mound postulated to be the site of ritual burial and of spiritual significance to the tribe, is located near the confluence of the two forks of the river and was documented by Thomas Jefferson in his work Notes on the State of Virginia, 1781. Several major habitations of the tribe were located along the Rivanna, including; Monasukapanough, near the headwaters of the river, and Rassawek, the principal town of the tribe, located at the confluence of the Rivanna and James rivers.

In the late eighteenth century the river was made navigable, partially by the efforts of the Jeffersons who owned much of the lands along its upper course, eg. Shadwell and Monticello. Improvements included in the first generation (through 1830) were sluice cuts, small dams and batteaux locks. Second generation (1840-1870) improvements had long stretches of canal, serviced by large locks, many of which are still visible along the river today. Shortly after the completion of the initial Rivanna navigational works Virginia requested that the river be opened to public usage. It is said Jefferson at first refused, but the commonwealth would not be denied, and the Rivanna became an integral part of the central Virginian transportation network.

The route serviced a large community of farmsteads and plantations throughout Albemarle and Fluvanna counties. It also bore ever-growing numbers of industrial facilities, like those at Union Mills. It was the construction of these larger mills which prompted the great "second generation" improvements to navigation which were coordinated by the Rivanna Navigation Company. Union Mills alone featured a two and a half mile long canal and towpath, one upper and two massive lower locks, all directly upon the river.

Where the Rivanna meets the James River at Columbia so too did the four and a half mile long Rivanna Connexion canal merge with the James River and Kanawha Canal, itself an altogether impressive work intended to connect Richmond, Va with the Ohio and the West. The series of locks which connected the two works lie just outside of the town, and are mostly buried by sediment today.

In the batteaux era Milton was the head of navigation along the river, but by the early nineteenth century horse-drawn canal boats were traveling all the way upstream to Charlottesville, where the head of navigation was located at the very point where the Fredericksburg Road (now VA 20) and Three Chopt Road (U.S. Route 250), the primary road to Richmond, met and entered the city at the Free Bridge, establishing the city as a major commercial hub.

During the late twentieth century the river saw the establishment of the Rivanna Trail, a greenbelt trail that encircles the city of Charlottesville. As its name suggests the trail was originally envisioned as a river-front promenade, after the San Antonio River Walk, but the plan was soon enlarged under the guidance of the [http://avenue.org/rivanna/home.html Rivanna Trails Foundation] . It now takes hikers all the way around Charlottesville, passing through many of the city's parks and the wooded lands surrounding it, totaling over 20 miles in length.

Course

The Rivanna River is formed in Albemarle County about 4 mi (6 km) northeast of Charlottesville by the confluence of two tributaries:

*The North Fork Rivanna River is formed in southwestern Greene County by the confluence of Parker Branch and the Roach River, and flows generally southwardly into Albemarle County, collecting the Lynch River.
*The South Fork Rivanna River is formed in Albemarle County by the confluence of the Moormans River and the Mechums River, and flows generally eastwardly.

Below this confluence, the Rivanna flows generally southeastwardly into Fluvanna County, past the eastern boundary of Charlottesville and through the Southwest Mountains. In Fluvanna County it passes the communities of Lake Monticello and Palmyra; it enters the James River at the town of Columbia.
