Lakes - Tennessee Lakes and Rivers

Percy Priest Lake, located in the heart of Middle Tennessee, is one of the most popular recreational destinations in the state. With its sprawling waters, scenic shoreline, and ample opportunities for outdoor activities, it’s no wonder that both locals and tourists flock to this beautiful lake. But how deep is Percy Priest Lake? This is a question that often arises among visitors and those planning their next adventure on the water. The Depth of Percy Priest Lake Percy Priest Lake has an average depth of 50 feet, making it a relatively shallow reservoir compared to some others in the region. However, the lake’s depth varies significantly across its expanse, reaching a maximum depth of 160 feet near the dam at the northeastern end. This variation in depth makes the lake suitable for a variety of water activities, from shallow-water fishing to deep-water scuba diving. To give you a better understanding of the lake’s topography, here’s a detailed look at some of the deepest spots across Percy Priest Lake: LocationDepth (Feet)Near J.

The Lake’s Unique Underwater Features One of the fascinating aspects of Percy Priest Lake is its diverse underwater landscape. The lake was created by damming the Stones River, and beneath the surface, you’ll find remnants of the old riverbed, hills, valleys, and even submerged structures from before the dam’s construction. Submerged Structures: Before the area was flooded, several communities and structures existed where the lake now sits. Some divers explore these submerged sites, though they are now heavily eroded and covered in silt. Underwater Ridges and Drop-offs: The varying depths create interesting underwater ridges and drop-offs, particularly near the dam and central basin. These areas are rich in fish and make for exciting exploration for advanced divers. Water Temperature and Its Impact on Depth The lake’s depth also influences water temperature, with cooler waters found at greater depths. During the summer, the surface waters can warm up significantly, while the deeper areas remain much cooler, providing a refuge for certain fish species and making the lake a popular spot for anglers. Thermal Stratification: Percy Priest Lake experiences thermal stratification, where the water separates into distinct layers based on temperature. The warmest layer is at the surface, and as you descend, the water becomes cooler. This stratification typically occurs in the summer and can affect where fish are located in the lake. Recreation and Activities at Percy Priest Lake Fishing: The lake is home to a variety of fish species, including bass, crappie, and catfish. The varying depths provide ideal conditions for different types of fishing, from shallow-water casting to deep-water trolling. Boating and Water Sports: The deeper waters near the dam and central basin are perfect for powerboating, water skiing, and jet skiing. The lake’s shallower coves are great for kayaking and paddleboarding. Scuba Diving: The lake’s deeper sections, especially near the dam, are popular with scuba divers. The underwater landscape includes remnants of the Stones River Valley, offering an intriguing environment for exploration. Swimming: With designated swimming areas and warm waters during the summer months, Percy Priest Lake is a popular spot for a refreshing swim. The lake’s depth in swimming areas is generally shallow, making it safe and enjoyable for families. Conservation and Lake Management Maintaining the health and depth of Percy Priest Lake is essential for preserving its natural beauty and recreational value. Sedimentation, shoreline erosion, and water level management are ongoing challenges that the U.S. Army Corps of Engineers and local conservation groups work to address. Sedimentation Management: Over time, sediment from the surrounding landscape accumulates at the bottom of the lake, potentially reducing its depth. Efforts are made to manage this sedimentation and keep the lake at its optimal depth for recreation and wildlife. Shoreline Protection: Erosion of the lake’s shoreline can contribute to sedimentation and impact water quality. Protective measures, such as planting vegetation and using barriers, help to preserve the shoreline. Percy Priest Lake is more than just a recreational spot; it’s a dynamic ecosystem shaped by its varying depths and underwater features. Whether you’re fishing, boating, diving, or simply enjoying the view, the lake’s depth plays a key role in the experience it offers. By understanding more about the depth of Percy Priest Lake, you can better appreciate the unique environment that makes it such a cherished destination in Tennessee.
