Delta Lake 2 and Delta Lake 1 dominate this South Texas landscape, anchoring a complex system of hydraulic engineering that sustains the local agricultural economy. The survey illustrates the critical role of water management in Willacy and Hidalgo counties, featuring the Main Branch Northeast Canal and the Main Supply Canal which navigate the flat coastal plain. In the settlement of Lasara, a grid of residential streets is flanked by several family and community burial grounds, including the Lasara Memorial Cem and Garcia Cem. Further south, the community of Monte Alto sits near the edges of the reservoir system. The map documents a rural network of farm-to-market roads and county lines, such as Co Line Rd and FM 88, which connect these small agricultural hubs and isolated water bodies like Teniente Wid Number 1 Lake and Harbin Reservoir.
