Seismicity map of the state of Colorado
C. W. Stover, B.G. Reagor, S. T. Algermissen
1984, Miscellaneous Field Studies Map 1694
The data shown on this map and listed in table 1 are for earthquakes that were originally included in a study of seismic risk in the United States (Algermissen, 1969). This data file has been recompiled and updated through 1981. Some revisions of epicenters and intensities in the original file...
Analysis of the Carmel Valley alluvial ground-water basin, Monterey County, California
Glenn W. Kapple, Hugh T. Mitten, Timothy J. Durbin, Michael J. Johnson
1984, Water-Resources Investigations Report 83-4280
A two-dimensional, finite-element, digital model was developed for the Carmel Valley alluvial ground-water basin using measured, computed, and estimated discharge and recharge data for the basin. Discharge data included evapotranspiration by phreatophytes and agricultural, municipal, and domestic pumpage. Recharge data included river leakage, tributary runoff, and pumping return flow. Recharge...

Aquifer tests at the Jackpile-Paguate uranium mine, Pueblo of Laguna, west-central New Mexico
D. W. Risser, P. A. Davis, J. A. Baldwin, D. P. McaAda
1984, Water-Resources Investigations Report 84-4255
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...
Cost effectiveness of the stream-gaging program in northeastern California
S.H. Hoffard, V.F. Pearce, Gary D. Tasker, W.H. Doyle
1984, Water-Resources Investigations Report 84-4127
Results are documented of a study of the cost effectiveness of the stream-gaging program in northeastern California. Data uses and funding sources were identified for the 127 continuous stream gages currently being operated in the study area. One stream gage was found to have insufficient data use to warrant cooperative...
