This document is Appendix A containing site photographs of the Barkley Spillway Gates machinery, which serves as visual reference material for a federal contract opportunity.

The appendix includes seven figures documenting the current condition and configuration of spillway gate machinery at Barkley Dam. Figure 1 depicts Gate 12 drive side machinery showing the primary drive assembly and control mechanisms on an elevated platform. Figure 2 shows a typical spillway chain maintenance platform with metal framework and safety railings positioned over the gate mechanism. Figure 3 provides a long-shot overview of the Gate 12 spillway bay, illustrating the gate structure within the spillway opening and surrounding concrete infrastructure. Figure 4 shows Gate 10 driven side machinery featuring a large wheel assembly and mechanical components mounted on a concrete sub-base with protective metal fencing. Figure 5 displays a typical drive machinery assembly at close range, revealing electrical motors, hydraulic components with blue connectors, and integrated control systems. Figure 6 documents the underside of Gate 10 drive side machinery sub-base, showing significant rust and corrosion indicative of age and environmental exposure. Figure 7 illustrates typical machinery sub-base condition with visible rust, deteriorated wooden structural elements, and evidence of extended service life. These photographs collectively establish the existing site conditions and document infrastructure requiring potential modernization, replacement, or maintenance work as part of the contract scope.
