Water Quality

Ground-water and surface-water quality is one of the most critical concerns in the State of Oklahoma. The major water-quality issue in Oklahoma is preserving the quality of public drinking-water supply. Water-resource planning and water-quality assessment require a nationwide database with standardized information for planning and assessment of water resources. Thus, the chemical and physical quality of rivers, streams, and ground water need to be monitored and defined to effectively manage the resource to meet needs of the people of Oklahoma and our present and future customers.

Hydrologic Summary for the Cheyenne and Arapaho Tribal Jurisdictional Area

The objectives of this proposed project are to compile and evaluate existing data and reports from the USGS, other government agencies, and tribes to summarize the types of data that have been collected in the area and identify gaps in those data. Such analysis will provide a comprehensive background document of geographic, hydrologic, and environmental features of the area and will identify...

Green Infrastructure, CECs, and Geochemistry in Urban Stormwater Runoff used to Recharge Groundwater

This national project is a joint effort between the USGS and EPA looking at contaminants of emerging concern (CECs) in urban stormwater runoff that is infiltrated into the subsurface or likely to be infiltrated in the future.

Phase I of the project aims to provide a broad-scale assessment of contaminants of emerging concern (CECs) and basic composition of water chemistry in urban...

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.

Water Budget Analysis of the Pawnee Tribe Jurisdictional Area in Payne County, OK

The objective of this proposed project is to construct an annual water budget for the Cimarron River alluvial aquifer between USGS streamgages Cimarron River near Ripley, OK and a proposed new USGS streamgage. Components of the water budget (precipitation, [runoff], evapotranspiration, stream base flow, bedrock lateral flow, and groundwater pumping) will be calculated for the 2017 water year (...

Black Bear Creek Watershed Hydrologic Summary for the Pawnee Nation of Oklahoma

The objectives of this project are to compile, summarize, and analyze available data and reports from the Pawnee Nation, the USGS, and other government agencies. The final report of the analysis will provide a comprehensive background document for geographic, hydrologic, and environmental features of the area and will identify gaps in available data that need to be filled for the Pawnee Nation...

Tonkawa Tribe Groundwater Survey

The objective of this study is to analyze the alluvial aquifer of the Chikaskia River to determine the potential for additional groundwater resources for the Tonkawa Tribe’s water supply. This investigation will examine the depth, lithology, hydraulic properties, and general water quality of the Chikaskia River alluvial aquifer.

Washita River Reach 3 and 4 Alluvial Aquifer Study

The objectives of this investigation are to describe the hydrogeology, and construct, calibrate, and use a numerical groundwater-flow model to simulate the effects of transient stresses and various pumping and climate scenarios for Reaches 3 and 4 of the Washita River alluvial aquifer.

Investigation of Hydrogeology and Water Availability in the Osage Nation of Oklahoma

The purpose of this project is to evaluate the spatial distribution and volume of the fresh and brackish (saline) groundwater resources on the Reservation of the Osage Nation in Oklahoma. This investigation will evaluate the sources of water and water use in the Reservation, through activities such as historical water use, characterization of water wells, and predicting the potential effects...

Oklahoma FloodWatch

By combining the historical record, data from ongoing streamgage monitoring, and data on new events, the USGS is able to develop the expertise and tools that help Federal, State, and local community leaders not only to enhance short-term preparation, aid, and recovery efforts, but to better understand how their flood risk may be changing over time and how they can reduce their risk in future...
