The current Master Manual titled Alabama Coosa River Basin Reservoir Regulation Manual is dated December 1951. An Individual manual for each is prepared as an appendix to the master manual. The current project manuals are listed below.

Carters Dam
The Corps' Carters Dam and Carters Reregulation Dam on the Coosawattee River is a multipurpose project for flood control, hydropower, navigation, water quality, fish and wildlife enhancement, and recreation. Carters Lake was authorized by the Rivers and Harbors Act of 1945 (PL 79-14, 59 Stat 10). The Carters project is a pumped-storage peaking facility. Water is released from Carters Dam, flows through the penstock, and generates power as it is discharged to the reregulation dam pool. The Corps generates power at Carters Dam only a few hours each weekday, when demand for electricity is greatest. When demand for electricity is low, usually during the night or on weekends, the turbines reverse and pump water back up from the reregulation pool to Carters Lake. Water is available again for hydropower generation in the next peak use period and Carters Lake is maintained at its optimal power generation level.

The Reregulation Dam serves two purposes: as a lower pool for the pumped storage operation and to reregulate peaking flows from Carters Dam to provide a more stable downstream flow.

Carters Lake has a total storage capacity of 472,800 acre feet at elevation 1,099 feet. Of this, 134,900 acre feet are usable for power generation, 95,700 acre feet are reserved for flood control, and 242,200 acre-feet is inactive storage. The minimum power pool elevation is 1,022 feet and the maximum power pool (maximum conservation pool) elevation is 1,074 feet in the summer and 1,072 feet in the winter. Carters Lake has a surface area of 3,220 acres at elevation 1,072 feet. The normal year-round operating range for the reregulation dam is 677 to 696 feet. The Carters Reregulation Dam provides a minimum continuous flow of 240 cfs to the Coosa River. The total generating capacity of the project is 575 megawatts (MW)

As expected with a peaking/pumped storage operation, both Carters Lake and the reregulation pool experience frequent elevation changes. Typically, water levels in Carters Lake vary no more than 1 to 2 feet per day. Levels can rise more than this during flooding events, however, as the lake captures and retains flood flows.

A minimum flow of about 250 cfs is continuously released through a service unit, which generates power while providing a constant flow to the Etowah River downstream. Allatoona Dam operates in a peaking mode, generating power between two and six hours during normal operations each weekday. Weekend generation may occur if required to meet customer needs. The period of power generation is related to the stage of Conservation pool drawdown.

Lake levels vary only several inches except during high inflows to the basin and during flood storage drawdown in the winter, which reduces the pool from 840 feet to 823 feet. Flood flows that are captured in the reservoir are generally released slowly over the subsequent weeks, unless additional flood flows are anticipated. Power releases during the low flow season augment flows at the Alabama Power Company projects along the Coosa River. The releases also provide water for municipal and industrial needs in the Rome, Georgia, area and for navigation on the Alabama River below Montgomery during the dry season.

Alabama River Projects
The Corps of Engineers (COE) projects on the Alabama River south of Montgomery, Alabama; Claiborne Lock and Dam, Millers Ferry Lock and Dam, and Robert F. Henry Lock and Dam, are operated for the purposes of navigation, hydroelectric power, recreation, and fish and wildlife.

Claiborne Lake is the most primitive of the three Alabama River Lakes. The lake remains mostly within its original river banks and is surrounded by a rustic atmosphere. The Corps is allowing the shoreline to revert to its natural state, providing important wildlife habitat. Recreation visitors number more than one million annually.

Millers Ferry Lock and Dam
The William "Bill" Dannelly Lake is created by the Millers Ferry Lock and Dam on the Alabama River, 178 miles upstream of Mobile Bay. Dannelly Lake is 103 miles long and averages almost 1,400 feet wide. The reservoir partially inundates several tributary streams. The Cahaba River flows into the upper reaches of Dannelly Lake.

Dannelly Lake has a storage capacity of 331,800 acre-feet at a normal pool elevation of 80 feet. It has a surface area of 18,500 acres. There is a 9-foot-deep by 200-foot-wide navigation channel extending the entire length of the reservoir. The facility is a multi-purpose reservoir constructed by the Corps for both navigation and hydropower. The reservoir also provides recreational benefits and has lands managed for wildlife mitigation. The hydropower generating capacity of the project is 90 MW. An average daily outflow of 6,600 cfs is provided from the Millers Ferry Dam for navigation and assimilative flow needs on the Alabama River.

Lake levels remain fairly stable on a day-to-day basis, but rise slightly, up to 0.5 feet, in wet weather. The reservoir provides ample recreation opportunities. Recreation visitors number 3 million annually.

Robert F. Henry Lock and Dam
The R.E. "Bob" Woodruff Lake is created by the Robert F. Henry Lock and Dam, located 281 miles upstream of Mobile Bay. This is the first of three Corps projects on the Alabama River, also known as the Alabama River Lakes. Woodruff Lake extends from the Robert F. Henry Lock and Dam upstream to the Walter Bouldin Dam. The City of Montgomery, Alabama, is located on the lake. In addition to hydropower and navigation, Woodruff Lake provides recreation and fish and wildlife enhancement.

Woodruff Lake is 77 miles long and averages 1,300 feet wide. It has a surface area of 12,500 acres and a storage capacity of 234,200 acre-feet at a normal pool elevation of 125 feet. There is a 9-foot-deep by 200-foot-wide navigation channel over the entire length of the lake. The Corps operates the project for navigation and hydropower generation. The facility has a generation capacity of 82 MW. The R.F. Henry Dam is operated in tandem with the downstream Millers Ferry Dam to provide an average daily outflow of 6,600 cfs from the Millers Ferry Dam for navigation and waste assimilation needs on the Alabama River.

Lake levels are typically fairly stable with minimal fluctuation. The lake is a popular recreation destination, receiving up to 2 million visitors annually.

Alabama Power Projects
The Weiss Dam, H. Neely Henry Dam, Logan Martin Dam and Harris Dam projects will be operated for flood damage reduction and navigation in accordance with regulations prescribed by the Secretary of the Army.
