These are technical mechanical drawings and schematic diagrams for the Ice Harbor Dam Intake Gate Hydraulic System Upgrades project, prepared by the US Army Corps of Engineers. The documents include detailed engineering specifications for hydraulic systems, focusing on transverse section layouts, cylinder arrangements, reservoir tanks, power unit schematics, and control systems. The drawings cover various technical aspects such as gate positioning, hydraulic pump controls, power unit configurations, and electrical wiring diagrams, with specific attention to the mechanical and electrical components required for upgrading the intake gate hydraulic systems at the dam site.

The technical drawings are comprehensive, featuring multiple sheets that provide top views, section views, and schematic representations of complex hydraulic and electrical systems. Key components detailed include hydraulic reservoirs, power pumps, control panels, valves, pressure gauges, and electrical motor controls. The documents are marked with the US Army Corps of Engineers logo and include general notes, legends, and technical specifications to guide the implementation of the hydraulic system upgrades, with a focus on precise engineering details and system interconnectivity.
