Tennessee's river systems are experiencing notably low streamflows across most of the state, signaling potential flow drought conditions and decreased water levels for water enthusiasts and local ecosystems. The majority of waterways are reporting flows well below their seasonal norms, with the New River at New River, Clear Fork near Robbins, and the South Fork Cumberland River at Leatherwood Ford all recording streamflows more than 85% below their typical levels, resulting in significantly lower gage heights such as 3.05 feet at New River. Contrastingly, the Cumberland River at Nashville has seen a substantial increase in streamflow in the past 24 hours, rising by 202.61 cubic feet per second (cfs) to a gage height of 18.19 feet, possibly indicating flood conditions that could impact Nashville and its surroundings.
Notably, the Nolichucky River at Embreeville is one of the few rivers bucking the trend, flowing at nearly 4% above normal, while the Pigeon River at Newport and the Ocoee River at Copperhill have experienced significant rises in the last day, by 25.49 cfs and 205.7 cfs respectively, which could alert whitewater enthusiasts to improved conditions. However, the widespread lower-than-average streamflows suggest caution for those planning river activities, as many popular whitewater trails may be affected by the limited water levels. Areas near major cities like Knoxville and Chattanooga, and along significant rivers such as the Harpeth, Little Pigeon, and Duck, are experiencing decreased streamflows that could impact recreational use and local wildlife. River-goers are advised to stay informed on current conditions and any advisories from local water management authorities.
Tennessee's flow conditions are influenced by its major rivers, including the Tennessee River, Cumberland River, and Mississippi River. These rivers are fed by numerous tributaries, including the Clinch River, Duck River, and Hiwassee River. The state's hydrology is characterized by significant rainfall, which can lead to high river levels and flooding. There are also several major reservoirs and dams in Tennessee, including the Norris Dam and the Kentucky Dam, which help to regulate water levels and generate hydropower. In addition, the state's climate is humid subtropical, with hot summers and mild winters. Watershed data and snowpack levels can also impact Tennessee's hydrology, with higher levels of snow melt leading to increased river flow.
Residents of northeast Tennessee, particularly those in the vicinity of Morristown, should exercise caution as occasional snow showers are expected to persist until mid-morning. Light snowfall has already resulted in a dusting on roads, rendering some untreated surfaces slippery, including bridges and overpasses. Commuters are advised to drive slowly, allow for extra travel time, and maintain a safe distance from other vehicles. Though accumulations are forecasted to be light, the National Weather Service urges the public to stay updated on the situation through NOAA Weather Radio or local media and to navigate roadways with care to ensure safety during this winter weather event.
