Geohydrology of the aquifer in the Santa Fe Group, northern West Mesa of the Mesilla Basin near Las Cruces, New Mexico

Because of the heterogeneity of the Santa Fe Group, New Mexico, the hydrologic characteristics of the aquifer vary substantially from place to place. Hydraulic conductivities of 12 and 30 feet per day were estimated from aquifer tests for two wells in the eastern one-half of the study area. Well yields in the western one-half of the study area generally are less than 5 gallons per minute. Some of the well yields in the eastern one-half of the study area are greater than 1,000 gallons per minute. Ground water flows southeastward across the western one-half of the study area at a gradient of about 50 feet per mile. Across the eastern one-half of the study area, ground water flows southeastward at a gradient of less than 5 feet per mile. Dissolved-solids concentrations in groundwater range from 906 to 1,470 milligrams per liter in the western one-half of the study area and from 378 to 556 milligrams per liter in the eastern one-half.

Spawning by Rhinichthys osculus (Cyprinidae), in the San Francisco River, New Mexico

The speckles dace Rhinichthys osculus [Girard] is the most widely distributed and ubiquitous fish in the western United States (Moyle, Inland Fishes of California, 1976). Although common, very little information is available concerning thje reproductive behavior of speckled dace or the environmental cues which trigger spawning activity. Several hundred speckled dace were observed spawning in the San Francisco River, 4.8 km upstream from Reserve, Catron County, New Mexico, on June 2-3, 1981. Spawning was in an area of disturbed substrate at a time when other reaches of the streambed were overgrown with diatoms, filamentous algae, and macrophytes. This note described the spawning site and reproductive behavior and proposes that physical disturbance is a major cue for reproductive activity in the species.

Hydrologic data on the Pueblos of Jemez, Zia, and Santa Ana, Sandoval County, New Mexico

This report presents currently available geohydrologic data on the Pueblos of Jemez, Zia, and Santa Ana. Data about the occurrence, quantity, and quality of water from wells, springs, and streams are presented in nine tables. Data are tabulated for 73 wells and 39 springs. Water quality analyses are presented for 26 wells and 19 springs. The location of data sites, water level altitudes for wells, land surface altitudes at springs, water quality data, and other information are shown on two plates. These data provide a base with which to better define the water resources of the three pueblos.

Maps showing distribution of dissolved solids and dominant chemical type in ground water, Basin and Range Province, New Mexico

This map report is one of a series of geologic and hydrologic maps of States in the Basin and Range Province. These map reports contain information on ground-water hydrology, ground-water quality, surface distribution of selected rock types, data on tectonic conditions, areal geophysical data, Pleistocene lakes and marshes and natural resources. This information is the basis for a summary report that characterizes the Basin and Range Province. The geologic and hydrologic characterization will be used to evaluate the Province for prospective regions for further study relative to isolation of high-level radioactive waste. (Bedinger, Sargent and Reed, 1984).

Aquifer tests at the Jackpile-Paguate uranium mine, Pueblo of Laguna, west-central New Mexico

The transmissivity of the Jackpile sandstone bed in the Brushy Basin Shale Member of the Morrison Formation, west-central New Mexico, was determined to be 24 sq ft/day at well M2 and 47 sq ft/day at well M3 from constant-discharge aquifer tests conducted at the Jackpile-Paguate Uranium Mine. The storage coefficient of the Jackpile sandstone bed was estimated to be 0.00018 at well M2 and 0.00029 at well M3 from the same tests. An aquifer test conducted at well M21 indicated the transmissivity of the Jackpile sandstone bed was 2.0 sq ft/day and the storage coefficient was 0.00002. The transmissivity of an unnamed sandstone bed in the Brushy Basin Shale Member of the Morrison Formation was estimated from ' slug-test ' results to be about 20 sq ft/day. Water levels in this sandstone probably did not change due to pumping from the overlying Jackpile sandstone bed for 88 hours at an average discharge of 15.3 gallons/min. A constant discharge aquifer test at well M4C indicated that the transmissivity of the alluvium at this location was about 430 sq ft/day. Water levels in the underlying Jackpile sandstone bed began declining within 15 minutes after withdrawals of groundwater from the alluvial aquifer began. (USGS)

Isopach and structure contour maps of the Burro Canyon(?) Formation in the Mesa Golondrina and Mesa de los Viejos areas, Chama Basin, New Mexico

In the Chama Basin a wequence of conglomerate, sandstone, and red, gray-green, and pale-purple mudstone occurs stratigraphically between the Upper Jurassic Morrison Formation and Upper Cretaceous Dakota Sandstone. This stratigraphic interval has been called the Burro Canyon Formation by several workers (Craig and others, 1959; Smith and others, 1961; Saucier, 1974). Although similarities in lithology and stratigraphic position exist between this unit and the Burro Canyon Formation in Colorado, no direct correlation has been made between the two. For this reason the unit in the Chama Basin is called the Burro Canyon(?) Formation.
