Kirk D. Rodgers, Ph.D.
Kirk Rodgers is a program analyst and hydrologist with the Southeast Region based in Little Rock, Arkansas.
Most recently, Kirk served as project manager and principal investigator for RESTORE, a combined $8.9 million dollar Gulf Coast Ecosystem Restoration Council funded “Baseline Flow, Gage Analysis & On-Line Tool to Support Restoration in Gulf States” and “Develop Ecological Decision-Support for Mobile and Perdido River Basins" projects with the USGS Lower Mississippi-Gulf Water Science Center. Kirk has worked with the National Water Quality Field Assessment as field lead for the Ozark Principal Aquifer Study and with the Reservoir Fisheries Habitat Partnership compiling a reservoir morphology database for the lower 48 states. In addition, he has worked in conjunction with the Arkansas Natural Resource Commission and the Arkansas Geological Survey analyzing and interpreting potentiometric surfaces of major aquifers in Arkansas. Kirk’s dissertation research focused on the compilation of a reservoir morphology database and the analysis of reservoir morphology in the continental United States. Kirk now serves as a program analyst and hydrologist for the Southeast Region where he works in Outreach and Oversight.

Compilation of estuarine salinity data for sites used in RESTORE Streamflow alteration assessments (ver. 2.0, May 2021) Compilation of estuarine salinity data for sites used in RESTORE Streamflow alteration assessments (ver. 2.0, May 2021)
The presence of salinity in shallow waters influences living resources and habitats within Gulf of Mexico estuaries. The salinity gradient is widely recognized as foundational in maintaining biological diversity and productivity of estuaries. A clear understanding of the factors controlling salinity and its variability in estuarine surface waters is essential for proper stewardship and...
Water-level data, selected water-quality data, and the potentiometric dataset for the Mississippi River Valley alluvial aquifer in eastern Arkansas, spring 2014 Water-level data, selected water-quality data, and the potentiometric dataset for the Mississippi River Valley alluvial aquifer in eastern Arkansas, spring 2014
The alluvial aquifer of the Mississippi embayment lies within a syncline plunging south towards the Gulf of Mexico with the axis of the syncline roughly following the Mississippi River (Cushing and others, 1964, Hart and others, 2008). The trough of the syncline is comprised of alluvial and terrace deposits of Quaternary age (Ackerman, 1996). A potentiometric-surface map of the...
Trend Departure Index Results for sites in the RESTORE Trend Analysis and Hydrologic Alteration Studies Trend Departure Index Results for sites in the RESTORE Trend Analysis and Hydrologic Alteration Studies
This dataset includes results of the Trend Departure Index (TDI) for 139 sites in the RESTORE trend analysis study and approximately 9,200 HUC12 pour points in the streamflow alteration study. Data from the 139 sites in the trend analysis were compared against reference site data from the GAGES II dataset (Falcone and others, 2010) and were used to calculate the departure from reference...
Geospatial data supporting assessments of streamflow alteration to support bay and estuary restoration in the Gulf States Geospatial data supporting assessments of streamflow alteration to support bay and estuary restoration in the Gulf States
The state-of-the-science for implementing restoration of flows for freshwater and estuarine ecosystems health has improved markedly. Many successful examples now exist for improving the timing and delivery of freshwater flows through collaborative processes such as modification of flow regimes through operational changes made through dam re-regulation, dam removal, conservation and...
Trend analysis results for sites used in RESTORE Streamflow alteration assessments Trend analysis results for sites used in RESTORE Streamflow alteration assessments
Daily streamflow discharge data from 139 streamgages located on tributaries and streams flowing to the Gulf of Mexico were used to calculate mean monthly, mean seasonal, and decile values. Streamgages used to calculate trends required a minimum of 65 years of continuous daily streamflow data. These values were used to analyze trends in streamflow using the Mann-Kendall trend test in the...
Potentiometric contours for the Nacatoch aquifer of Northeastern and Southwestern Arkansas and the Tokio aquifer of Southwestern Arkansas, 201415 Potentiometric contours for the Nacatoch aquifer of Northeastern and Southwestern Arkansas and the Tokio aquifer of Southwestern Arkansas, 201415
The Nacatoch Sand in northeastern and southwestern Arkansas and the Tokio Formation in southwestern Arkansas are sources of groundwater for agricultural, domestic, industrial, and public use. Water-level altitudes measured in 51 wells completed in the Nacatoch Sand and 42 wells completed in the Tokio Formation during 2014 and 2015 were used to compile potentiometric-surface maps of the...

Potentiometric surfaces and water-level trends in the Cockfield (upper Claiborne) aquifer in southern Arkansas and the Wilcox (lower Wilcox) aquifer of northeastern and southern Arkansas, 2012 Potentiometric surfaces and water-level trends in the Cockfield (upper Claiborne) aquifer in southern Arkansas and the Wilcox (lower Wilcox) aquifer of northeastern and southern Arkansas, 2012
The Cockfield aquifer, located in southern Arkansas, is composed of Eocene-age sand beds found near the base of the Cockfield Formation of Claiborne Group. The Wilcox aquifer, located in northeastern and southern Arkansas, is composed of Paleocene-age sand beds found in the middle to lower part of the Wilcox Group. The Cockfield and Wilcox aquifers are primary sources of groundwater. In...
