Reservoir Development Impacts on Surface-Water Quantity and Quality in the Yampa River Basin, Colorado and Wyoming
From introduction: This report describes the results of an investigation in which three computer models were used to evaluate different levels of the proposed reservoir development. One model simulated streamflow conditions with alternative multireservoir configurations; a second model simulated the dissolved-solids concentrations at various locations in the basin; and a third model used streamflows and dissolved solids concentrations to simulate the water-quality conditions within certain proposed reservoirs. This study was designed to demonstrate the application of computer-modeling techniques in evaluating impacts of proposed reservoirs.

Longwall Gate Road Stability in a Steeply Pitching Thick Coal Seam with a Weak Roof
The U.S. Bureau of Mines (USBM) conducted ground pressure analysis of a wide abutment-type chain pillar in a two-entry gate road of a Western U.S. coal mine with an extremely weak immediate roof. About 15 m of fragile, low-strength mudstone lies between the seam and the lowest competent roof member. Three- and two-entry gate road designs with several pillar sizes and various secondary support systems have been employed to improve tailgate-entry stability, with varying results. This report discusses gate road layout and performance and secondary support effectiveness. The results of the pillar pressure study are compared to pillar loading predicted by a widely used pillar design method and to similar studies in other mines. A stability evaluation of the most recent longwall headgate, using the USBM Analysis of Longwall Pillar Stability (ALPS) method, indicates marginal stability in first-panel mining and instability in second-panel mining. The ALPS method and the USBM Coal Mine Roof Rating system are used to evaluate tailgate-mining stability of the previous gate roads and to determine pillar and entry width and top coal thickness criteria for tailgate stability in future panels.

Geomorphology of the North Flank of the Uinta Mountains
From introduction: The geologic record of the Tertiary period in the Green River Basin of southwestern Wyoming consists, in a broad way, of two quite different parts. The history of the first part, lasting through the Eocene epoch and perhaps on into the early Oligocene, was recorded in a thick series of sedimentary rocks of fluviatile and lacustrine origin. The history of the second part was recorded chiefly by successive stages of stream planation and stream trenching, but also in part by fluviatile sedimentation and, in certain localities, by glacial deposits. The first part of the record is virtually continuous, though its interpretation is by no means simple and obvious. The second part of the record is distinctly fragmentary, and the evidence the fragments provide is difficult to evaluate and to integrate.

The Recognizable Species of the Green River Flora
Abstract: The identification of new collections of fossil plants from the Green River formation of middle Eocene age made it necessary to reexamine the megascopic types of the Green River flora. This study resulted in the reassignment of some species and the rejection of such species as were based on fragmentary, indefinable specimens. The recent collections yielded 22 new species. Exclusive of the microscopic forms of thallophytes and pollens, the flora now numbers 135 megascopic species that are considered to be recognizable and distinctive. The new elements found in the flora do not alter the previously expressed opinion that the megascopic Green River flora lived in a warm-temperate well-watered environment.

Hydrogeologic Features of the Alluvial Deposits in the Greybull River Valley, Bighorn Basin, Wyoming
Abstract: The alluvial aquifer along the Greybull River consists principally of the Greybull terrace deposits and the flood-plain alluvium but also includes the Burlington terrace deposits and the flood-plain alluvium but also includes the Burlington terrace deposits east of Burlington, the McKinnie terrace, and the younger, generally undissected alluvial-fan deposits. Well-log data and 18 surface-resistivity measurements at four localities indicate that the thickness of the alluvial aquifer is as much as 60 feet thick only near Burlington and Otto. The most favorable area for development of ground water from the alluvial aquifer is near Burlington and Otto where relatively large amounts of water can be obtained from the Greybull terrace deposits and the flood-plain alluvium. Elsewhere, the deposits of the alluvial aquifer yield only small amounts of water to wells.
Hydrogeologic Features of the Alluvial Deposits in the Owl Creek Valley, Bighorn Basin, Wyoming
Introduction: The alluvial deposits form the principal aquifer in the Owl Creek Valley and the source of water to many stock and domestic wells and to a few irrigation wells. In 1975, the U.S. Geological Survey, in cooperation with the Wyoming State Engineer, began an investigation of the hydrology and geology, including the geomorphology, of Owl Creek Valley (fig. 1) to determine possible favorable areas for obtaining ground water of adequate chemical quality for irrigation and other uses. The part of Owl Creek basin investigated is downstream from Anchor Reservoir and includes North Fork, South Fork, and the mainstem of Owl Creek (pi. 1). However, the area downstream from Embar Ranch (pi. 1) was emphasized during the study.
