This document contains project location maps and technical drawings for the Orwell Dam project near Fergus Falls, Minnesota. The first page shows both a regional location map placing the dam in Minnesota near the South Dakota border, and a detailed vicinity map showing the dam's specific location in relation to nearby roads and features like Rush Lake. The second page (J-8) contains detailed engineering drawings of the spillway including plan and section views showing structural components. The third page presents a detailed mechanical plan focused on the tainter gate machinery layout with an accompanying scope of work listing required maintenance and repairs. The fourth page shows photographs from 2003 documenting the installation of an 80 CFS by-pass pipe system at the dam.

The technical drawings and photographs appear to support the current solicitation W912ES25QA005 for de-watering maintenance by-pass services at Orwell Dam, providing historical context and technical reference for contractors to understand the site conditions and previous by-pass system implementation. The drawings include specific measurements, elevations, and structural details that would be relevant for planning the required 80 CFS by-pass flow system installation scheduled for September 2025.
