Groundwater Monitoring on Fort Sill Apache Tribal Lands

This USGS investigation will examine the hydraulic properties of the Rush Springs aquifer underlying Fort Sill Apache tribal lands to determine their potential for groundwater development. The information gathered from this investigation will assist the Fort Sill Apache Tribe in identifying well locations with optimal long-term pumping capacity and water quality.

Guemes Island

Aquifer Recharge Area Study of Guemes Island

The Issue: Guemes Island is an 8.2-square-mile island in the northern part of Puget Sound in western Washington State. The population of the island is increasing, as is the demand for groundwater, which is the island's sole source of freshwater. Continued growth and development of the island, particularly in nearshore areas, has led to the increasing failure of nearshore wells due to seawater...

MODFLOW-NWT model used in Simulation of Groundwater Flow, and Analysis of Projected Water Use for the Washita River Alluvial Aquifer, Western Oklahoma

In 2020 the U.S. Geological Survey, in cooperation with the Oklahoma Water Resources Board, published a calibrated numerical groundwater-flow model and associated model documentation report that evaluated the effects of potential groundwater withdrawals on groundwater flow and availability in the Washita River alluvial aquifer in western Oklahoma. The results of groundwater-availability scenarios

Hydrogeology and simulation of groundwater flow and analysis of projected water use for the Canadian River alluvial aquifer, western and central Oklahoma

This report describes a study of the hydrogeology and simulation of groundwater flow for the Canadian River alluvial aquifer in western and central Oklahoma conducted by the U.S. Geological Survey in cooperation with the Oklahoma Water Resources Board. The report (1) quantifies the groundwater resources of the Canadian River alluvial aquifer by developing a conceptual model, (2) summarizes the gen

Hydrogeology, numerical simulation of groundwater flow, and effects of future water use and drought for reach 1 of the Washita River alluvial aquifer, Roger Mills and Custer Counties, western Oklahoma, 1980–2015

The Washita River alluvial aquifer is a valley-fill and terrace alluvial aquifer along the valley of the Washita River in western Oklahoma that provides a productive source of groundwater for agricultural irrigation and water supply. The Oklahoma Water Resources Board (OWRB) has designated the westernmost section of the aquifer in Roger Mills and Custer Counties, Okla., as reach 1 of the Washita R
