Boone Lake is a reservoir in Sullivan and Washington counties in northeastern Tennessee, formed by the impoundment of the South Fork Holston River and Watauga River behind Boone Dam.[http://www.tva.com/sites/boone.htm Boone Reservoir information] {{webarchive |url=https://web.archive.org/web/20080515234342/http://www.tva.com/sites/boone.htm |date=May 15, 2008 }}, Tennessee Valley Authority Boone Reservoir’s {{convert|4,400|acres}} extend along the South Fork Holston River forming two river extensions. According to TVA, “at maximum pool level, one arm of the lake extends about {{convert|16|miles}} up the South Fork Holston River, and the other extends approximately {{convert|15|miles}} up the Watauga River".

The dam and reservoir are maintained and operated by the Tennessee Valley Authority (TVA). The lake has a surface area of about {{convert|4400|acre|km2|sigfig=2}} and a flood-storage capacity of {{convert|75829|acre.ft|m3|lk=in}}. Water levels in the reservoir fluctuate over a range of about {{convert|20|ft|m|sigfig=1}} over the course of a year.

Boone Lake may house one of the smaller lakes that the state has to offer, but the lakefront real estate packs a southern punch - with the average cost of shorefront property sitting at a cool $1.37 million according to a 2020 study.{{Cite web|url=https://www.redbookmag.com/life/g28169050/most-expensive-lakes-to-live-on-in-america/|author=Alex Aronson|title=The Most Expensive Lakes to Live on in America

|date=November 2, 2020|website=Redbook}} This places Boone Lake as the sixteenth most expensive lake shorefront property in the United States. At the time of the study, the dam repair was still underway; greatly reducing the accessibility, aesthetics and shoreline of the lake.

Recreational facilities on the lake include a swimming area and a boat ramp. Water skiing and fishing are popular activities on the lake. Fish species in the lake of interest to sport fishermen include brown trout, lake trout, rainbow trout, largemouth bass, smallmouth bass, and striped bass.[http://www.tva.gov/environment/water/sportfish.htm Sport Fishing Index Ratings] {{webarchive|url=https://web.archive.org/web/20070427152737/http://www.tva.gov/environment/water/sportfish.htm |date=2007-04-27 }}, Tennessee Valley Authority website (accessed June 8, 2008) There are precautionary fish consumption advisories for catfish and carp due to PCB and chlordane concentrations.Gregory M.
