Nance Ferry is a boat ramp access point on the Holston River in Blaine, Grainger County, Tennessee. The Holston River at this location is a major waterway classified as stream order 8, comparable to rivers like the Mississippi and Missouri. With an average flow of approximately 4,890 cubic feet per second and an average velocity of 4.97 feet per second, this section of river provides moderate current conditions typical of a large river system. The gradient averages 2.5 feet per mile, indicating a relatively steady downstream slope.
Boaters using Nance Ferry should be aware that the Holston River in this area experiences moderate current and maintains significant volume year-round. The river's 137-mile length and substantial drainage area of 3,642 square miles mean this is a major regional waterway. The elevation drop of 349 feet over the entire river's length suggests variable conditions at different locations along the system. This access point serves as a launch location for both recreational and fishing activities on one of East Tennessee's primary river corridors.
