ABSTRACT
On Tutuila, American Samoa, weather monitoring and stream gauging operations were initiated by the United States Geological Survey (USGS) in the 1950s. However, as of 2008, all USGS monitoring activity on Tutuila had ceased. Although this legacy data remains as a valuable tool, climate change and variability continues to reduce its viability as time passes. Because this information is a critical component of sustainable water management, the University of Hawaii (UH) Water Resources Research Center (WRRC) and the territory’s sole water utility, American Samoa Power Authority (ASPA) have entered into a cooperative agreement for the purpose of developing a new weather station, stream gauging, and aquifer monitoring network. The instruments used in this network are intended to be simple, robust, and easily maintained to ensure longevity and continuity of data. Weather stations have been placed at pre-existing ASPA leased locations, and stream gauges are sited near roads, bridges, or previously gauged sites for ease of access and maintenance. Aquifer data is monitored at available locations within the existing ASPA well network. The goal of this project is to produce publicly available long-term hydrological datasets for use in water resource management or other applications.
