Lithium brine potential of North Dakota: Results from the 2025 sampling program
Lithium (Li), classified as a critical mineral and key in energy storage applications because of its high energy density, faces unprecedented demand. This has driven interest in unconventional sources of Li, especially brines from sedimentary basins. Accordingly, the spatial distribution of basinal brinehosted Li resources across North America is becoming better defined, including the Williston Basin underlying Saskatchewan, Canada. This has led to growing investment and exploration by industry throughout the 2020s; however, despite this interest, the Li potential of basinal brines of the Williston Basin in North Dakota remain underexplored. This work presents the results from the 2025 joint brine sampling campaign between the North Dakota Geological Survey, the United States Geological Survey (USGS), and The University of Texas at Austin. Twenty-seven fluid samples were collected from producing oil and water source wells from eight stratigraphic intervals across western North Dakota and analyzed for major cation and anion concentrations. Similar to southeastern Saskatchewan, the highest Li concentrations were identified in the Devonian Duperow Formation, with concentrations up to 179 mg/L being observed in a well commingled between the Duperow and Red River Formations. Some samples from the overlying Birdbear Formation exceeded 75 mg/L, whereas Li concentrations were lower in the Madison Group (33-44 mg/L) and the Three Forks (50 mg/L), Dawson Bay (43 mg/L), Winnipegosis (23 mg/L), and Red River (40.0 mg/L) Formations. This work indicates Li resource potential exists across the Williston Basin and advances our understanding of the Li distribution in basinal brines which could provide a new domestic source of this critical mineral.
Stream measurement work: Chapter 7 in Fifteenth biennial report of the State Engineer to the governor of Utah: 1925-1926
The general stream measurement work has been continued during the biennium by the United States Geological Survey under cooperative agreement with the State Engineer. This agreement is essentially the same as that outlined in previous reports and the details of the stream gauging operations carried on under these agreements can be found in the biennial reports of the State Engineer. The data collected are published in the annual water supply papers of the United States Geological Survey which contain stream flow records for the whole United States including Alaska and Hawaii. For convenience and uniformity in publications the United States has been divided into 12 primary drainage basins and the results of stream measurements are published annually in a series of progress reports that correspond to these twelve divisions. Data for Utah appear in two of these: the Great Basin and the Colorado River basin reports. A complete set of these publications is on fine at the district office of the Geological Survey, 313 Federal Building, Salt Lake City, where the data in advance of publication are also available.
U. S. Geological Survey Flagstaff Field Center
The United States Geological Survey Flagstaff Field Center was founded by the late Eugene Shoemaker in 1963 as a research site for the new science of planetary geology. Flagstaffs clear air and high elevation made it a desirable location for telescope observations of the Moon and planets and nearby Meteor Crater was a superb training ground for the Apollo astronauts. There, and in the volcanic fields surrounding Flagstaff, astronauts tested equipment and were taught to look at the Moon through the eyes of a geologist.
Summary of records of surface waters of Texas, 1898-1937
The first gaging station In Texas urns established on the Rio Grande at El Paso on May 10, 1889, under the provisions of the Act of Congress of October 2, 1888, which authorized the organization of the Irrigation Survey by the United States Geological Survey. A few miscellaneous measurements of streams In central Texas, between Del Rio and Austin, were made, by C. C. Babb of the Geological Survey in 1894, 1895, and 1896. In 1897 T. U. Taylor, professor of civil engineering at the University of Texas, at Austin, began a systematic study for the Geological Survey of as many of the principal streams as the limited funds would permit. In the same year the American section of the International Water Commission began collecting records of flow of the Rio Grande in Texas. Records for the Rio Grande and some of its tributaries from 1897 to 1913, inclusive, collected by that commission under the immediate direction of W. W. Follett, United States consulting engineer, are contained in Geological Survey Water-supply Paper 358. It was not until 1915, when the State Legislature appropriated funds for stream measurement investigations by the Texas Board of Water Engineers, that a substantial beginning toward the systematic collection of stream-flow records was made. The work has been continued and enlarged gradually so that records have been collected at about 230 stations in Texas. In September 1937 86 gaging stations were being maintained in Texas by the Geological Survey and the cooperating agencies. Many miscellaneous discharge measurements have been made at other points. The records collected by the Geological Survey from 1889 to 1937 are now scattered through more than 50 reports, many of which are out of print.

Proceedings of a workshop on digital mapping techniques; methods for geologic map data capture, management, and publication - June 2 - 5, 1997, Lawrence, Kansas
Introduction: From June 2-5, 1997, selected technical representatives of the USGS and State geological surveys participated in the 'AASG/USGS Digital Mapping Techniques' workshop in Lawrence, Kansas. The workshop was initiated by the AASG/USGS Data Capture Working Group, and was hosted by the Kansas Geological Survey (KGS). With a focus on methods for data capture and digital map production, the goal was to help move the state surveys and the USGS toward development of more cost-effective, flexible, and useful systems for digital mapping and GIS analysis.
Water-resources program of the Geological Survey in the Midwestern States
The program of basic water-resources investigations by the U.S Geological Survey in the Midwestern states is a highly coordinated undertaking. It represents a partnership among Federal, State, and participial agencies that has developed during the past 60 years from the mutual desire to obtain and maintain optimum knowledge of out water resources with a minimum outlay of public funds. The program is sufficiently broad to include investigations of water from all natural sources including the chemical and physical quality of water from each of these sources.
Using 222Rn to examine groundwater/surface discharge interaction in the Rio Grande de Manati, Puerto Rico
222 Rn was used in the karst drainage basin of the Rio Grande de Manati in Puerto Rico to study groundwater/surface flow relationships. Locations of groundwater influx along two sections of the Rio Grande de Manati were identified. The 222 Rn measurements were used together with stream discharge data in a mass balance equation to quantify the groundwater inputs. The investigation established that both of the sections of the Rio Manati surveyed not only gained groundwater, but lost surface flow. It was calculated that the river gained about 1.2m 3 s −1 and lost 0.5m 3 s −1 to the aquifer between Ciales and United States Geological Survey gauging station 5. Between United States Geological Survey gauging stations 6 and 7, groundwater influx and stream flow loss occurred simultaneously with groundwater inputs equalling surface discharge losses of 4m 3 s −1 . The study successfully demonstrated the innovative application of 222 Rn as a geochemical tracer in examining groundwater/surface flow relationships in a karst system.
Geology and ground-water resources of the "Equus beds" area in south central Kansas
This paper summarizes the results of a detailed investigation by the U. S. Geological Survey in cooperation with the Kansas State Geological Survey, Kansas State Board of Health, and the City of Wichita. The geology of the area has been remapped, and several new formations have been established, including the Emma Creek formation of middle and upper Pliocene age, and a thick loess deposit. The hydrologic studies involved extensive test drilling and resulted in the development of a new groundwater supply for the City of Wichita.

Water resources of Beaver Valley, Utah
Location and extent of area examined. Beaver Valley is located in Beaver County, in southwestern Utah, about 175 miles south of Salt Lake. It lies between the Tushar Mountains on the east and the Beaver Mountains on the west. The principal town of the valley is Beaver, which is most conveniently reached from Milford, a station on the San Pedro, Los Angeles and Salt Lake Railroad. The valley, together with its neighboring highlands, occupies the eastern third of Beaver County, an area of about 1,200 square miles. A large part of this area, however, is rocky upland and unproductive desert, the tillable land comprising a comparatively small area in the immediate vicinity of the streams. Purpose and scope of work . The purpose of this paper is to present information concerning the waters of Beaver Valley and to point out ways and means of increasing their usefulness. The presence of a large amount of water in Beaver Valley results from local topograhic conditions, the water being supplied by precipitation in the highland to the east. Its conservation and distribution result from geologic conditions, the water being held in loose gravel and sand, which are more or less confined between ridges of consolidated rocks. The rock basins were formed partly by erosion and partly by faulting and surface deformation. In order to accomplish the purpose in view it is therefore necessary to describe the geographic and geologic conditions in Beaver Valley and neighboring regions. The investigation included the determination of the flow of streams and springs, of the manner of occurrence and quantity of the underground waters as shown by the geologic and geographic conditions of the region and by the distribution of springs and wells, and of the chemical character of the waters with reference to their adaptability to domestic use and to irrigation. The chemical data were obtained (a) by field assays, which are approximately correct and probably of sufficient accuracy to be of value in comparing the various waters; (b) by more exact analyses, some of which were made in the laboratory of the United States Geological Survey by W. M. Barr, and others by Herman Harms, State chemist of Utah, for the San Pedro, Los Angeles and Salt Lake Railroad; and (c) by sanitary analyses, made also by Herman Harms. Cooperation . The work was done during the summer of 1906, the United States Geological Survey cooperating with the State of Utah through Caleb Tanner, State engineer, and with the county of Beaver through the supervisors of the county. In collecting the information the writer was assisted by J. F. Hoyt, of Nephi, Utah.
Surface waters of Kansas, 1919-1924
The Kansas legislature in 1917 passed the Water Commission act, entitled, "An act relating to floods, drainage, water power, domestic water supply, navigation, irrigation, and providing for state control of all matters relating thereto, and providing for a Water Commission in the state of Kansas." Under this act the Water Commission was created and authorized to investigate the problems relating to floods, drainage, water power, domestic water supply, navigation and irrigation. It was, however, limited in this work on account of the appropriation provided, and it has therefore confined its investigations to stream-gaging work in the principal watersheds of Kansas. This work has been carried out under a cooperative agreement entered into with the United States Geological Survey. Previous to the formation of the Kansas Water Commission the State Board of Irrigation Survey, Experiment and Demonstration cooperated with the United States Geological Survey in the stream-gaging investigations in Kansas from 1895 to 1906. Work by the United States Geological Survey was begun in 1895 by Arthur P. Davis, under the direction of F. H. Newell, chief hydrographer. E. C. Murphy, professor of engineering in the Kansas State University at Lawrence, Kan., was in charge of the work in eastern Kansas, and W. G. Russell was in charge of the work in western Kansas. Prof. O. P. Hood, of the Kansas State Agricultural College, Manhattan, Kan., cooperated in maintaining the gaging station on the Blue river near Manhattan. During 1904, 1905 and part of 1906, M. C. Hinderlider was district hydrographer. From 1906 to 1916 no stream-gaging investigations were made in Kansas, and the only records available for this period are those of river stages taken by the United States Weather Bureau, at a few selected stations, for use by the river forcast service. The floods of 1908, 1909 and 1915 occurred during this period.
Ground-water data collected in the Missouri River basin units in Kansas during 1948
Ground-water studies in the Missouri River Basin were begun by the U.S. Geological Survey during the fall of 1945 as a part of the program for development of the resources of the basin by the U.S. Bureau of Reclamation and other Federal agencies. The studies of the ground-water resources in the part of Kansas that lies within the basin have been coordinated with the cooperative program of ground-water studies already being carried on in Kansas by the Federal Geological Survey and the Kansas State Geological Survey with the cooperation of the Division of Sanitation of the Kansas State Board of health and the Division of Water Resources of the Kansas State Board of Agriculture. Areas in which ground-water data have been collected under the Missouri Basin program include the Almena Unit in Norton and Phillips Counties; the Bostwick Unit in Jewell, Republic, and Cloud Counties; the Cedar Bluff Unit in Ellis and Trego Counties; the Glen Elder Unit in Mitchell County; the Kanopolis Unit in McPherson and Saline Counties; the Kirwin Unit in Phillips, Smith, and Osborne Counties; the St. Francis Unit in Cheyenne County; the Webster Unit in Osborne County; and the Wilson Unit in Lincoln County. Most of the ground-water data presented in this report were collected during 1948. Most of the data collected in these areas prior to the end of 1947 were presented in a report mimeographed in September 1948. This report and the previous report are the first two of a series of annual reports on ground-water studies in the Missouri Basin units in Kansas. These reports are a means of more promptly releasing for administrative use the data collected each year. Data for a given area that are included in the annual reports will be assembled later in a report on the geology and hydrology of that area.
The current status of woodcock and woodcock surveys in the United States
A comparison of American woodcock (Philohela minor) wing collection survey data for 1975-76 and 1976-77 showed that there was little change in the indices to breeding success and hunter success between years in the Atlantic and Central regions. The 1977 breeding population index was up 15.2 percent from 1976 in the Central region and static in the Atlantic region. There is a long-term decline in the breeding population index in the Atlantic region (P < 0.01) and a long-term increase (P < 0.05) in the Central region's breeding population index. Present survey analysis methods are discussed, and a four-phase plan to improve the methods is presented.
