This document is a technical blueprint and schematic set for the Hungry Horse Dam facility, specifically detailing the first floor elevation at 3067.00 feet.

The drawings depict a hydroelectric powerhouse configuration with four operational units (Unit No. 1, Unit No. 2, Unit No. 3, and Unit No. 4) arranged in a linear layout. Key structural elements include the Penstock Gallery at elevation 3067.00, the Pipe Gallery at elevation 3080.00, and the Unwatering Gallery at the base. The plan view shows the spatial arrangement of the units with associated water and air hookups, floor hatches, and approximate locations for contractor storage and adit receptacles. The section views illustrate the vertical relationship between galleries, the circular turbine chambers (shown in cross-section), and the complex underground infrastructure including penstock connections, floor drains, and structural support systems. Detailed technical specifications on page three include component specifications, dimensional tolerances, notes on materials and construction requirements, and equipment installation details such as runner blade configurations and discharge characteristics for the hydraulic turbines. The drawings contain multiple reference circles and detailed callouts indicating specific construction notes, material specifications, and assembly requirements throughout the facility design. All elevations, dimensions, and construction details are precisely annotated to guide the engineering and construction processes.
