Overview

In 1934 and 1935, the Tennessee Valley Authority established 51 daily record suspended-sediment stations on the Tennessee River and its major tributaries. Most of these stations were operated for 8 years. From 1962 to 1965, the Tennessee Valley Authority again collected daily sediment record at 10 of the original 49 stations. In addition to the data sets collected on the major rivers, the Tennessee Valley Authority has conducted several intensive studies of small watersheds throughout the Tennessee River basin. In the Cumberland River basin, daily sediment records have been collected primarily by the Survey. Daily stations have been operated for various periods on 17 basins ranging in size from 0.67 to 1,977 sq mi, with the earliest data of daily record being October 1953. All of these daily stations are located in the upper Cumberland River basin upstream of any major impoundments. Periodic sediment data have been collected by the Survey at 194 stations in the Tennessee River basin and at 106 stations in the Cumberland River basin, however; the number of samples/station is quite low. 86% of the periodic stations in the Tennessee River basin and 91% of the periodic stations in the Cumberland River basin have 30 samples or less.
