Groundwater Well Yield in Wake County, North Carolina The U.S. Geological Survey, in cooperation with Wake County Environmental Services, initiated a comprehensive groundwater resource investigation to better understand the quantity and quality of groundwater in Wake County, North Carolina. In 2020, as part of the investigation, groundwater records were compiled electronically from 7,689 wells in and within five miles of Wake County and groundwater yield data was interpolated to estimate maximum well yield across the county. Maximum well yield values estimate the maximum well yield possible at a given location; the maximum well yield is not guaranteed and actual well yield likely falls within the range of 0 and the maximum well yield value. This data release includes...

The model was developed as part of a study to assess groundwater availability in the fractured-rock aquifers underlying Wake County. Curve number, maximum net infiltration rate, and root-zone depth parameters for all land cover classes were adjusted in the SWB model to manually test parameter sensitivity and adjust for best fit. Annual net infiltration estimates from the SWB model were also compared with annual base flow estimates from the PART hydrograph separation technique using the USGS Groundwater Toolbox (Barlow and others,...

The new version can be found at https://doi.org/10.5066/P95XKK5V. A Soil-Water-Balance (SWB) model was developed to estimate annual net infiltration below the root-zone for the Greater Wake County Area, North Carolina for the period 1981 through 2019 and project future estimates from 2020 through 2070. The model was developed as part of a study to assess groundwater availability in the fractured-rock aquifers underlying Wake County. The model is documented in the associated report, U.S. Geological Survey (USGS) Scientific Investigations Report 2022-5041. Comparison was done with annual base-flow estimates from the PART hydrograph separation technique for available years of...

The water-bearing potential of the units was determined from rock origin, composition, and texture as described in Daniel (1989) and Daniel and Payne (1990) for the Piedmont and Blue Ridge Provinces of North Carolina. A layer file is also included to provide the map symbology used in the report.
