Evin Fetkovich
Hydrologist, Oklahoma Branch, Oklahoma-Texas Water Science Center
Evin Fetkovich is a Hydrologist with the USGS Oklahoma-Texas Water Science Center in Oklahoma City, Ok. He joined the USGS in the Tulsa field office in 2019 where his work mostly focused on water quality. He joined the Oklahoma City Hydrologic Studies section in 2021 as a Hydrologist. His research interests include groundwater availability, developing hydrogeologic frameworks and conceptual flow models, water quality, and he is beginning work on projects involving groundwater modeling using MODFLOW. Evin is also a member of the USGS Early Career Scientists Network Employee Resource Group leadership team.

Soil-water-balance model and data used in the hydrogeologic investigation, framework, and conceptual flow model of the Antlers aquifer, southeastern Oklahoma, 1967–2022
This archive contains the data used to (1) summarize the hydrogeology and update the hydrogeologic framework of the Antlers aquifer in southeastern Oklahoma, and (2) develop a conceptual groundwater-flow model and water budget to estimate recharge to the Antlers aquifer during 1980–2022 as part of a hydrologic investigation (the model documentation report is available at https://doi.org...
MODFLOW-NWT model used in simulation of groundwater availability in reaches 3 and 4 of the Washita River aquifer, southern Oklahoma, 1980–2017
The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB), constructed a finite-difference numerical groundwater-flow model of the Washita River aquifer by using MODFLOW-2005 (Harbaugh, 2005) with the Newton formulation solver (MODFLOW-NWT). The 1973 Oklahoma Groundwater Law requires that the OWRB conduct hydrologic investigations of the State’s...
Hydrogeologic investigation, framework, and conceptual flow model of the Antlers aquifer, southeastern Oklahoma, 1980–2022
The 1973 Oklahoma Groundwater Law (Oklahoma Statute §82–1020.5) requires that the Oklahoma Water Resources Board conduct hydrologic investigations of the State’s groundwater basins to support a determination of the maximum annual yield for each groundwater basin. Every 20 years, the Oklahoma Water Resources Board is required to update the hydrologic investigation on which the maximum...

Comparison of hydrologic data and water budgets between 2003–08 and 2018–23 for the eastern part of the Arbuckle-Simpson aquifer, south-central Oklahoma
The Arbuckle-Simpson aquifer is divided spatially into three parts (eastern, central, and western). The largest groundwater withdrawals are from the eastern part of the Arbuckle-Simpson aquifer, which provides water to approximately 39,000 people in Ada and Sulphur, Oklahoma, and surrounding areas. The Arbuckle-Simpson aquifer, including the eastern part, is designated a sole source...

Hydrogeology and simulated groundwater availability in reaches 3 and 4 of the Washita River aquifer, southern Oklahoma, 1980–2017
The 1973 Oklahoma Groundwater Law (Oklahoma Statutes §82–1020.5) requires that the Oklahoma Water Resources Board conduct hydrologic investigations of the State’s aquifers to determine the maximum annual yield for each groundwater basin. Because more than 20 years have elapsed since the final order was issued, the U.S. Geological Survey, in cooperation with the Oklahoma Water Resources...
