Percy Priest Dam
Percy Priest Dam is a major water resource infrastructure facility located approximately 20 miles east of downtown Nashville, Tennessee, in Rutherford County. Completed in 1968, the dam creates Percy Priest Lake, a 14,200-acre reservoir that serves multiple critical functions including flood control, water supply, recreation, and hydroelectric power generation. Named after a 19th-century Methodist minister and pioneer who settled in the area, the dam stands approximately 65 feet in height and spans roughly 6,400 feet across the Stones River. As one of Middle Tennessee's most significant engineering projects and recreational destinations, Percy Priest Dam has profoundly influenced the region's development, environmental management, and quality of life for nearly six decades.
History
The construction of Percy Priest Dam emerged from decades of planning and advocacy by Middle Tennessee communities seeking flood control and water management solutions. The Stones River, which the dam impounds, had historically experienced devastating flood events that threatened Nashville and surrounding areas. Following the major floods of 1937 and subsequent severe flooding throughout the mid-20th century, the U.S. Army Corps of Engineers conducted extensive studies to develop comprehensive water management strategies for the Cumberland River basin and its tributaries. In the early 1960s, federal authorization and funding were secured for the dam project, which represented a significant investment in regional infrastructure development.[1]
Construction of Percy Priest Dam began in 1965 and proceeded through 1968, involving substantial civil engineering efforts to construct the rolled earth and concrete structure across the Stones River valley. The project required the relocation of several families and businesses from the area that would be inundated by the reservoir. Upon completion in 1968, the dam immediately began impounding water to form Percy Priest Lake, which eventually reached its full capacity and became a defining landscape feature of Rutherford County. The reservoir's creation fundamentally altered the hydrology of the region, providing long-sought flood protection to downstream communities while simultaneously generating a major recreational resource. Over the subsequent decades, the dam has been maintained and periodically upgraded by the U.S. Army Corps of Engineers, Nashville District, which continues to operate the facility according to strict water management protocols designed to balance flood control, water supply, and environmental stewardship.[2]
Geography
Percy Priest Lake, formed by the impoundment created by the dam, covers approximately 14,200 acres at full pool elevation and extends for roughly 42 miles along the Stones River valley. The reservoir's shoreline is highly irregular, featuring numerous coves, inlets, and peninsulas that provide diverse habitat types and recreational access points. The lake's maximum depth reaches approximately 65 feet near the dam, though depths vary considerably throughout the reservoir depending on proximity to the original river channel. Elevation changes across the surrounding landscape create varied topography that transitions from steeper terrain near the dam to more gently rolling hills in the upper portions of the reservoir. The surrounding region features mixed hardwood and pine forests typical of Middle Tennessee's ecological character, supporting diverse wildlife populations including white-tailed deer, wild turkeys, bald eagles, and numerous fish species.
The Stones River, which the dam intercepts, originates in Rutherford County and flows westward through Murfreesboro before reaching the dam site near the community of Smyrna. The river's watershed encompasses several hundred square miles of Middle Tennessee terrain, contributing seasonal flow variations that the reservoir must accommodate. The lake's position in the regional hydrology makes it a critical component of downstream water management, affecting flows toward the Cumberland River and ultimately the Mississippi River system. Percy Priest Lake's geographic location within the Nashville metropolitan area's eastern expansion has made waterfront property increasingly valuable, with residential and commercial development gradually encroaching upon areas adjacent to the reservoir. The dam's spillway and operational features reflect engineering design standards that were contemporary in the 1960s, though modern water management protocols have evolved considerably since the facility's original construction.[3]
Recreation and Attractions
Percy Priest Lake has become one of Middle Tennessee's premier recreational destinations, attracting hundreds of thousands of visitors annually who participate in boating, fishing, swimming, camping, and other water-based activities. The reservoir supports a thriving recreational fishing industry, with abundant populations of largemouth bass, striped bass, crappie, and catfish drawing anglers from throughout the region and beyond. Multiple public boat launch facilities operated by the U.S. Army Corps of Engineers provide access to the water, with major facilities including the Smyrna Beach area, Anderson Road access point, and several other developed recreation sites around the lake's perimeter. Fishing tournaments sponsored by bass clubs and professional organizations regularly utilize Percy Priest Lake as a venue, with tournaments generating significant economic activity in surrounding communities.
The lake's recreational infrastructure includes several day-use areas with picnic facilities, swimming beaches, and scenic overlooks that serve both local residents and tourists visiting the Nashville metropolitan area. Percy Priest Lake's accessibility from Nashville—approximately 30 minutes by car from downtown—has made it a convenient destination for metropolitan residents seeking outdoor recreation without extended travel. The reservoir's scenic qualities have also made it an attractive location for photography, wildlife observation, and nature study, with the surrounding area offering opportunities to observe migratory waterfowl and resident bird populations. Environmental education programs and interpretive facilities help visitors understand the dam's water management functions and the ecological significance of the reservoir and surrounding lands. The lake's recreational value has created economic benefits for marinas, restaurants, lodging facilities, and retail businesses in nearby Smyrna, Murfreesboro, and other surrounding communities that serve the recreational economy.[4]
Water Management and Environmental Significance
Percy Priest Dam serves critical water management functions that extend far beyond recreation, operating as an essential component of Middle Tennessee's water supply and flood control infrastructure. The reservoir's storage capacity enables water supply authorities to maintain reliable supplies during drought periods while simultaneously providing flood attenuation during high-flow events. The Nashville Metropolitan Government and surrounding water systems rely upon Percy Priest Lake as a source of municipal and industrial water, making the facility essential to regional economic activity and public health. Water quality management in the reservoir requires ongoing monitoring and maintenance to ensure that the impounded water meets standards established by the Tennessee Department of Environment and Conservation and the Environmental Protection Agency.
The dam's operation follows complex management protocols that balance competing water management objectives throughout the year. During winter and early spring months, the Corps of Engineers maintains lower pool elevations to provide capacity for expected spring runoff and potential flood events. As spring progresses and summer approaches, pool elevation typically rises to support recreational activities and municipal water supply needs. Drought management becomes increasingly important during late summer and fall months when precipitation decreases and water demand from municipal, industrial, and agricultural users remains substantial. The reservoir's ecological role has become increasingly recognized, with water management strategies now incorporating considerations for maintaining habitat for fish and wildlife populations that depend upon the reservoir's waters and surrounding lands. Environmental challenges including invasive aquatic species management, watershed pollution control, and land use coordination require ongoing attention from resource management agencies.
Percy Priest Dam remains one of Nashville's most significant infrastructure facilities, providing essential services that enable the region's continued growth and development while supporting recreational and environmental values. The facility's importance to regional water security and flood protection ensures its continued central role in Middle Tennessee's water management framework for decades to come.
