The dataset folder entitled “SabLa” holds data structures consisting of statistical predictions of daily salinity time series for the Sabine Lake (SabLa) group, generated from the makESTUSAL software repository described by Asquith and others (2023b). The statistical methods included multiple methods of machine learning, which produced the daily salinity prediction and attendant credible uncertainties included in the data release. The geographic scope of the SabLa group includes the predictions for two locations defined using agency code and salinity site abbreviations.

The Nacatoch Sand in southwestern Arkansas, hereafter referred to as the Nacatoch aquifer, is a source of groundwater for agricultural, domestic, industrial, and public use in Clark, Hempstead, Little River, Miller, and Nevada counties. Water-level altitudes measured in 39 wells completed in the Nacatoch aquifer were used to create a potentiometric-surface map. Groundwater flow direction is towards the south and southeast in Hempstead, Little River, and Nevada Counties in southwestern Arkansas. A possible cone of depression may exist in southern Clark County and likely alters groundwater flow from a regional direction toward the depression. This shapefile depicts the generalized study area of the Southwest Nacatoch...

The Tokio Formation in southwestern Arkansas, hereafter referred to as the Tokio aquifer, is a source of groundwater for agricultural, domestic, industrial, and public use in Clark, Hempstead, Little River, Miller, Nevada, and Pike counties. Water-level altitudes measured 42 wells completed in the Tokio aquifer during 2014 and 2015 were used to create a potentiometric-surface map. In southwestern Arkansas, potentiometric surfaces indicate that groundwater flow in the Tokio aquifer is towards the city of Hope. Northwest of the city of Hope, a cone of depression may exist. In southwestern Pike, northwestern Nevada, and northeastern Hempstead Counties, an area of artesian flow (water levels are at or above land surface)...

The dataset folder entitled “FloCo” holds data structures consisting of statistical predictions of daily salinity time series for the North Florida Gulf Coast (FloCo) group, generated from the makESTUSAL software repository described by Asquith and others (2023b). The statistical methods included multiple methods of machine learning, which produced the daily salinity prediction and attendant credible uncertainties included in the data release. The geographic scope of the FloCo group includes the predictions for ten locations defined using agency code and salinity site abbreviations.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
