Data for: Application of a SWAT Model for Supporting a Ridge-to-Reef Framework in the Pago Watershed in Guam

This study implemented experimental and numerical approaches for supporting the Pago Bay ridge-to-reef management program. Water quality tests for turbidity and inorganic dissolved nitrogen (IDN) were performed using water samples collected from four sites within the Pago Watershed. Water sampling has been conducted two times per week for a 9-week period (June 9, 2021–August 4, 2021). The additional sampling is performed to investigate storm implications on water quality by comparing water quality data from before and after storms. Historical daily precipitation, temperature, and discharge data were used for developing a SWAT model.
