Canal Repairs Project Documentation

This document is a technical specification and location map for canal repairs managed by the Bureau of Reclamation. The project encompasses the Main Outlet Drain Extension and associated canal infrastructure in Arizona's Yuma County. The scope includes concrete lining work with both required and optional concrete panel work (FY08), multiple bridge structures, siphons, checks, and drainage improvements across various numbered stations along the canal system extending from the U.S.-Mexico border northward through Yuma County toward Phoenix.

The technical specifications detail typical concrete lining sections and cross-sectional modes for the canal, including standard concrete lining configurations, expansion joint details (Type 1 and Type 2), and groove details for the main outlet drain and bypass structures. The reference points legend identifies 26 specific infrastructure elements including bypass structures at various locations (STA. 0+50 AH Bypass Drain, STA. 195+86 Check, STA. 251+68 Bridge, STA. 200+35 Bridge, and others), each with corresponding elevation and structural specifications. The document indicates this is the Canal Repairs FY 2026 project with location map reference 423-303-60177, providing comprehensive engineering documentation for irrigation infrastructure maintenance and expansion work across the Main Outlet Drain Extension system.
