This project will include the removal of several existing components, configuration, labeling, and deployment of sensors, telemetry systems, and related components. The system shall be programmed to automatically upload collected data to the MIDAS cloud platform. Projects will be setup in the MIDAS cloud platform by USACE prior to any programming.

1.0 Project Overview:

Wolf Creek Dam is located in Russell County, Kentucky on the Cumberland River, which is

460.9 miles above its confluence with the Ohio River. The dam has a maximum height of 258-ft and is over a mile long. The structure consists of an earthen embankment and concrete gravity structure which includes a spillway, powerhouse and two non-overflow sections. The dam routinely stores and releases water through its 10 spillway gates, six hydropower turbines and lower-level sluice gates. Today, in addition to its originally authorized purposes, Wolf Creek

Dam and Lake Cumberland which it impounds provides recreation, water supply, and water quality benefits for the basin. Performance is monitored by automated and manually read piezometers, manually read inclinometers, and survey monumentation. Automated piezometers are read every hour, while manually read piezometers are read approximately weekly.

Center Hill Dam is located near Smithville, TN and impounds the Caney Fork River, a major tributary of the Cumberland River. The dam has a maximum height of 226 feet, a total length of

2,160 feet, and consists of a concrete gravity section, earthen embankment, saddle dike topped with a fuse plug and powerhouse. The dam routinely stores and releases water through its eight spillway gates, three hydropower turbines, and six low level sluice gates. The spillway gates play a major role in water release during significant storm events. Center Hill Dam impounds Center

Hill Lake which has a total storage capacity of 2,100,000 acre-ft. In addition to its originally authorized purposes of flood control and hydropower, Center Hill Dam and Lake provide recreation, water supply, and water quality benefits for the basin and region. Performance is monitored by automated and manually read piezometers, manually read inclinometers, and survey monumentation. Automated piezometers are read every hour, while manually read piezometers are read approximately weekly.
