Calibration watersheds used in the Maine Soil-Water-Balance model and location of the study area.

Land use for the Maine Soil-Water-Balance model.

DayMet average annual precipitation, 1991 to 2015, for the Maine Soil-Water-Balance model.

Simulated 25-year minimum annual potential recharge to groundwater for Maine, 1991 to 2015.

Locations of active wells (at least one measurement during the previous year) in the New England groundwater level network at the end of 2017. The dataset contains 104 wells with continuous water-level measurements (15-minute to hourly measurements), 182 wells with discrete water-level measurements (monthly measurements at most locations), and 95 wells with intermittent water-level measurements.
