This document is a location map and technical canal sections/details drawing for the Bureau of Reclamation's Canal Repairs Fiscal Year 2027 project in Arizona Yuma County. The document provides geographic reference points and engineering specifications for canal infrastructure work in the area bounded by the U.S.-Mexico border, Wellton, and the Colorado River.

The first page displays a regional location map identifying U.S. Bypass reference points with numbered stations (ranging from approximately 0+00 to 1741 stations) along canal segments from Morelos Dam through Yuma County to the U.S.-Mexico boundary pumping plant. The map includes coordinates referenced to township and range designations and notes that dots may represent multiple tasks. The second page contains technical cross-sectional drawings showing typical concrete lining configurations for the Main Outlet Drain Extension, including standard canal sections, expansion joint details (Type 1 and Type 2), and groove details. Specifications shown include concrete lining dimensions, reinforcement bar placements, water surface elevations, and construction details such as canal slope configurations ranging from 1 V/3 H to 1 V/2 H. Notes indicate drawings are not to scale and universal baseline approximations are 3 inches, with concrete panel increases to 3 1/2" for segments over approximately 1 mile in length.
