A Water Utilities GIS on the La Jolla Indian Reservation
Track: Tribal/Indigenous GIS programs
Author(s): Tia Morita, Rob Roy

Water is an essential element of life, and as an essential government service, Native American Tribes must ensure the delivery of clean drinking water on their reservations. However, limited resources can challenge management and delivery of this most basic service. In an effort to improve water utilities management, the La Jolla Band of Luiseņo Indians initiated a GIS project to map and analyze their domestic water system. The creation of a geometric data model required the integration of incompatible data sources (paper, CAD, digital, mental) into a comprehensive geodatabase using ArcGIS. Network analysis identified system weaknesses and helped to focus resources for future water projects; thus, resulting in more directed repairs and maintenance, and improved service delivery to residents. This project speaks to the utility of GIS to further the ability of tribes to function as full-service governments and provides a potential framework for replication across other reservations in California.
