Reconnaissance of ground water in vicinity of Wichita Mountains southwestern Oklahoma
Urbanization and industrial growth have increased demands on water supplies in the vicinity of the Wichita Mountains in southwestern Oklahoma. The principal city, Lawton, uses surface water, supplemented by small quantities of ground water from the Arbuckle Group (Cambrian-Ordovician), for industrial and recreational use. During periods of drought, surface-water supplies in the Wichita Mountains area are not adequate to meet fully the increased water demands. An alternative source of water may be ground water from the Arbuckle Group. Other urban and rural consumers use ground water from Quaternary alluvium, the Rush Springs Formation (Permian), or the Arbuckle Group.

Altitude and configuration of the 1980 water table in the High Plains regional aquifer, northwestern Oklahoma
The High Plains aquifer in Oklahoma is part of a regional aquifer system extending from South Dakota on the north through Wyoming, Colorado Nebraska Kansas, and Oklahoma to Texas and New Mexico on the south (index map) . The principal aquifer, the Ogallala Formation of Tertiary age, is hydraulically connected with other unconsolidated . deposits, principally of Quaternary age . Alluvium and terrace deposits in hydrologic continuity with the Qgallala are included in the High Plains aquifer in Oklahoma. Parts of the underlying bedrock also are hydraulically connected with the Ogallala. The High Plains aquifer in Oklahoma has been eroded on the west, exposing underlying rocks of Cretaceous age, and on the east, exposing rocks of Permian age. During 1978, the U.S. Geological Survey began a 5-year study of the High Plains regional aquifer system to provide hydrologic information for evaluation of the effects of long-term development of the aquifer and to develop computer models for prediction of aquifer response to alternative changes in ground-water management (Weeks, 1978). This report is one of a series presenting hydrologic information of the High Plains aquifer in Oklahoma. The altitude and configuration of the water table are shown for the eastern area, consisting of Harper, Ellis, Woodward, Dewey, and Roger Mills Counties (sheet 1), and for the Panhandle area, consisting of Cimarron, Texas, and Beaver Counties (sheet 2). Water levels were measured in January, February, and March 1980 by the Oklahoma Water Resources Board.

Hydrology of the Arbuckle Mountain area, south-central Oklahoma
Rocks that make up the Arbuckle-Simpson aquifer crop out over about 500 square miles in the Arbuckle Mountains province in south-central Oklahoma. The aquifer consists of limestone, dolomite, and sandstone of the Arbuckle and Simpson Groups of Late Cambrian to Middle Ordovician age and is about 5,000 to 9,000 feet thick. The rocks were subjected to intensive folding and faulting associated with major uplift of the area during Early to Late Pennsylvanian time. Water in the aquifer is confined in some parts of the area, while in other parts it is unconfined. The average saturated thickness of the aquifer is about 3,500 feet in the outcrop area. Water levels measured in wells fluctuated from 8 to 53 feet each year, primarily in response to recharge from rainfall. Recharge to the aquifer is estimated at about 4.7 inches per year. The average storage coefficient of the aquifer is estimated at 0.008, and the average transmissivity is estimated at 15,000 feet squared per day. Based on an average saturated thickness of about 3,500 feet and a storage coefficient of 0.008, the volume of ground water contained in the 500-square-mile outcrop area is about 9 million acre-feet. An undetermined amount of fresh water probably exists in the aquifer around the periphery of the aquifer outcrop. Base flow of streams that drain the aquifer accounts for about 60 percent of the total annual runoff from the outcrop area and is maintained by numerous springs. The close hydraulic connection between streams in the outcrop area and the aquifer is shown by a close correlation between base flow in Blue River and the fluctuation of ground-water levels in five wells in the Blue River basin. This correlation also exists between the discharge by Byrds Mill Spring and the fluctuation in water level in a nearby observation well; increase and decrease in spring discharge correspond to rise and fall of the water level in the well. The chemical quality of water from the Arbuckle-Simpson aquifer is suitable for most industrial and municipal uses. The water is hard and of the bicarbonate type; the average hardness is about 340 milligrams per liter, and the average dissolved-solids concentration is about 360 milligrams per liter. Because springs issue from the aquifer and discharge to streams in the area, the quality of water from springs and base flow in streams is similar to that of ground water. The average dissolved-solids concentration of stream water is slightly less than that of water from wells and springs.

Preliminary projections of the effects of chloride-control structures on the Quaternary aquifer at Great Salt Plains, Oklahoma
About 1,200 tons of chloride per day are added to the salt load of the Salt Fork Arkansas River at Great Salt Plains Lake.from brine discharge from the rocks of Permian age in the vicinity of the lake. The U.S. Army Corps of Engineers has planned a chloride-control project. The Corps requested that the U.S. Geological Survey use a digital model to project the effects of the chloride-control structures on ground water. Ground-water flow and ground-water transport models were calibrated to represent the Quaternary aquifer (the near-surface part of the flow system). Although ground-water levels are projected to rise as much as 19 feet in areas near three reservoirs, changes in ground-water levels caused by the project will be small throughout most of the area. Chloride concentration of ground water is projected to increase by more than 90,000 milligrams per liter at one location. However, significant increases in chloride concentration during the 50-near period simulated are projected to be limited to areas where the ground water already contains excessive chloride concentrations.

Water type and suitability of Oklahoma surface waters for public supply and irrigation, Part 5: Washita river basin through 1979
Water-quality data through 1979 in the Washita River basin within Oklahoma were examined for water type and suitability for public water supply and for irrigation use. Of 82 stations with available data, 32 stations or 39 percent were considered to have sufficient data for analysis. The classification of water type was based on the relation of the major ions: calcium, magnesium, sodium, carbonate, bicarbonate, sulfate, and chloride to each other within the range of measured specific conductance. The suitability for use as a public supply was based on the concentration distribution of selected constituents. The constitu ents selected were those with maximum contaminant levels established by regulation, or constituents for which recommended maximum limits have been established and for which historic data are available. The irriga tion classification method of Wilcox was used to relate sodium, calcium, and magnesium concentrations and the salinity distribution to the suita bility for use of the water for irrigation. Where data were available, the chance of phytotoxic effects by boron was discussed.

Use of Landsat data to evaluate lesser prairie chicken habitats in western Oklahoma
Landsat digital data were used to evaluate lesser prairie chicken (Tympanuchus pallidicinctus) habitats in western Oklahoma. Data for 7 (4,144 ha) study areas, 4 in shinnery oak (Quercus havardii), and 3 in sand sagebrush (Artemisia filifolia) rangeland, were analyzed using the Interactive Digital Image Manipulation System at the EROS Center. In shinnery oak rangeland, density of displaying males was correlated positively with percentage of area in grassland classes and negatively correlated with the percentage in brushland classes. In sand sagebrush rangeland, density of displaying males was negatively, but not significantly correlated with percentage of area in bare soil and grassland classes, and positively, but not significantly correlated with percentage of area in brushland classes. The trends found between density of displaying males and the Landsat-generated resource classes closely parallel similar relationships found with field sampling techniques. Analysis of the Landsat digital data for this study cost 13.8 cents/ha. Because larger areas could have been analyzed with the same digital data, the unit cost for analysis would decline with increasingly larger areas.

Organic geochemistry of the 9.6 km Bertha Rogers No. 1. well, Oklahoma
Organic geochemical analyses of fine-grained rocks from the 9.590 km Bertha Rogers No. 1 well have been carried out: total organic carbon, Soxhlet extraction and silica gel chromatography, C 15+ saturated and aromatic hydrocarbon gas chromatography and mass spectrometry, pyrolysis, kerogen analysis, X-ray diffraction and visual kerogen analysis. Rocks ranged in age from Permian to Ordovician; the well has an estimated bottom hole temperature of 225°C. Some data from this study are inconsistent with conventional theories concerning the generation and thermal destruction of hydrocarbons. For example, appreciable amounts of C 15+ gas-condensate-like hydrocarbons are present in very old rocks currently at temperatures where current theory predicts that only methane and graphite should remain. Also, substantial amounts of pyrolyzable C 15+ hydrocarbons remain on the kerogen in these deeply buried Paleozoic rocks. This suggests, at least in somes cases, that temperatures much higher than those predicted by current theory are required for generation and thermal destruction of hydrocarbons. The data from this well also suggest that original composition of organic matter and environment of deposition may have a much stronger influence on the organic geochemical characteristics of fine-grained sediments than has previously been ascribed to them. The results from this well, from other deep hot wells in which temperatures exceed 200°C, and from laboratory experiments, suggest that some of the basic concepts of the generation and maturation of petroleum hydrocarbons may be in error and perhaps should be reexamined.

Seismicity map of the State of Oklahoma
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States (Algermissen, 1969) which have been recompiled and updated through 1979. These data have been reexamined which resulted in some revisions of epicenters and intensities as well as assignment of intensities to earthquakes that previously had none assigned. Only earthquakes located within the boundary of the State are listed in table 1 even though earthquakes in bordering states or countries may have been felt or caused damage in the state. Intensity values were updated from new and additional data sources that were not available at the time of original compilation. Some epicenters were relocated on the basis of new information. The data shown in table 1 are estimates of the most accurate epicenter, magnitude, and intensity of each earthquake, on the basis of historical and current information. Some of the aftershocks from large earthquakes are listed but are incomplete in many instances, especially for the ones that occurred before seismic instruments were in universal usage.

Hydrologic data for the alluvium and terrace aquifer of the Beaver-North Canadian River from the Panhandle to Canton Reservoir, northwestern Oklahoma
The U.S. Geological Survey has collected data on Oklahoma's groundwater resources since 1934. The data in this report were collected as part of a study in cooperation with the Oklahoma Water Resources Board to evaluate the geohydrology of the alluvium and terrace aquifer of the Beaver-North Canadian River 4] in northwestern Oklahoma. The data include records of approximately 900 wells, test-holes, and springs, results of chemical analyses of water from 30 wells tapping the aquifer, monthly water-level measurements for selected wells, and low-flow discharge measurements of the Beaver-North Canadian River and its tributaries (plate 1). All of the data were collected in the field during the period 1977-79. Information prior to this period is not included in this report but is contained in reports by Wood and Stacy (1965) and Morton (in press). The stratigraphic nomenclature is that of the Oklahoma Geological Survey and does.not necessarily agree with that of the U.S. Geological Survey. Acknowledgement is extended to the residents of the study area for their cooperation in obtaining the data in this report.

Geohydrology and numerical simulation of the alluvium and terrace aquifer along the Beaver-North Canadian River from the Panhandle to Canton Lake, northwestern Oklahoma
A quantitative description of the hydrologic system in alluvium and terrace deposits along the Beaver-North Canadian River in northwestern Oklahoma is needed as an aid for planning and management of the aquifer. A two-dimensional finite-difference model was used to describe the aquifer and to predict the effects of future ground-water withdrawals. The aquifer principally consists of three geologic units: Alluvium with an average thickness of 30 feet, low terrace deposits with an average thickness of 50 feet, and high terrace deposits with an average thickness of 70 feet. A thin cover of dune sand overlies much of the area and provides an excellent catchment for recharge, but is generally unsaturated. Hydraulic conductivity of the aquifer ranges from 0 to 160 feet per day and averages 59 feet per day. Specific yield is estimated to be 0.29. Recharge to the aquifer is approximately 1 inch annually. Under present conditions (1978), most discharge is the result of ground-water flow to the Beaver-North Canadian River at a rate of 36 cubic feet per second and to pumpage for public-supply, industrial, and irrigation use at a rate of 28 cubic feet per second. In 1978, the aquifer had an average saturated thickness of 31 feet and contained 4.07 million acre-feet of water. The model was used to predict future head response in the aquifer to various pumping stresses. For any one area, the pumping stress was applied until the saturated thickness for that area was less than 5 feet, at which time the pumping ceased. The results of the modeled projections show that if the aquifer is stressed from 1978 to 1993 at the 1977 pumpage rates and well distribution, the average saturated thickness will decrease 1.0 foot and the volume of water in storage will be 3.94 million acre-feet, or 97 percent of the 1978 volume. If the aquifer is stressed at this same rate until 2020, the average saturated thickness will decrease an additional 0.7 foot and the volume of water in storage will be 3.84 million acre-feet, or 94 percent of the 1978 volume. If all areas of the aquifer having a 1978 saturated thickness of 5 feet or more are stressed from 1978 to 1993 at a rate of approximately 1.4 acre-feet per acre per year, the average saturated thickness will decrease by 20.9 feet and the volume of water in storage will be 1.28 million acre-feet, or 31 percent of the 1978 volume. If the aquifer is stressed at this same rate until 2020, the average saturated thickness will decrease an additional 2.2 feet and the volume of water in storage will be 980,000 acre-feet, or 24 percent of the 1978 volume. The water in the aquifer is generally of the calcium bicarbonate type and is suitable for most uses. Most of the 30 water samples analyzed contained less than 500 milligrams of dissolved solids per liter.
