Summary

This set of data includes four potential annual recharge grids for the State of Maine that were simulated using the Maine Soil-Water-Balance model for 1991 through 2015. The files include a grid representing the uncertainty in the potential recharge and a grid showing the annual average precipitation from the climate dataset that the simulation is based on. A 25-year simulation of potential recharge to groundwater from the Maine Soil-Water-Balance model for the years 1991 to 2015 produced annual results from which the four potential recharge grids were derived. The four are: 25-year mean, median, maximum, and minimum simulated annual potential. A data exclusion zone (see Scientific Investigations Report 2019-5125) has been applied [...]

Purpose

These data are intended to provide an initial estimate of potential recharge to groundwater in Maine in areas where site-specific studies have not yet been conducted. An appropriate use of these data would be to estimate an annual average potential groundwater recharge rate for areas greater than 2 square miles, using the accompanying Monte Carlo Standard Deviation grid to calculate the uncertainty in the simulated potential recharge, in the form of a standard deviation of the estimates for the area in question. The purpose of the average precipitation grid is to present the climatic context for the simulation. Caveats on the data presented can be found in the Missing Information section.
