Shortly after the Nolichucky and Pigeon rivers flow into the French Broad River, Douglas Dam impounds the river to form Douglas Lake. The dam was spilling a record amount of water, 450,000 gallons ...
The flushing flow method involves partially or completely emptying the reservoir behind a dam to erode the sediment stored on the bottom and transport it downstream. [7] [6] Flushing flows aim to restore natural water and sediment fluxes in the river downstream of the dam, however the flushing flow method is less costly compared to removing dams or constructing bypass tunnels.
Among TVA's biggest fans are fishers who can now catch trout downstream from Norris Dam. Here's why 'Healing': Why TVA moved 3,200 tons of rock to restore an island and its aquatic ecosystem

Norris Dam is a hydroelectric and flood control structure located on the Clinch River in Anderson County and Campbell County, Tennessee, United States.The dam was the first major project for the Tennessee Valley Authority, which had been created in 1933 to bring economic development to the region and control the rampant flooding that had long plagued the Tennessee Valley.

The Tennessee Valley Authority (TVA) and U.S. Army Corps of Engineers operate many hydroelectric dams on the Tennessee and Cumberland rivers and their tributaries. These dams form many large reservoirs throughout the state. [41] About half the state's land area is in the Tennessee Valley drainage basin of the Tennessee River. [38]
Since the lake has a greater fish density than most reservoirs maintained by the TVA, it has become one of the most popular for anglers in the East Tennessee region. [10] In 2019, Cherokee Lake was ranked #20 by Bassmaster of the top 25 bass fishing lakes in the Southeastern United States. [11]
During droughts, TVA and the Corps of Engineers release water from dams to keep the Tennessee and Cumberland rivers navigable. These rivers support $35 billion in annual shipping. The agencies try to keep channels at least eleven feet deep, because lower river levels can force barges to carry smaller loads, which increases transportation costs.
