Snowpack chemistry at selected sites in Colorado and New Mexico during winter 1999-2000
George P. Ingersoll
2000, Open-File Report 2000-394
Snowpacks at two high-elevation (> 3,000 m) sampling sites near McPhee and Sanchez Reservoirs in southern Colorado were selected to collect representative samples of atmospheric deposition to the surrounding watersheds during winter 1999-2000. In February 2000, annual snowpacks at two sites were sampled to determine concentrations of nitrate and sulfate;...

MODFLOW-2000, the U.S. Geological Survey Modular Ground-Water Model; documentation of packages for simulating evapotranspiration with a segmented function (ETS1) and drains with return flow (DRT1)
Edward R. Banta
2000, Open-File Report 2000-466
Two new packages for the U.S. Geological Survey modular finite-difference ground-water-flow model MODFLOW-2000 are documented. The new packages provide flexibility in simulating evapotranspiration and drain features not provided by the MODFLOW-2000 Evapotranspiration (EVT) and Drain (DRN) Packages. The report describes conceptualization of the packages, input instructions, listings and explanations of...
Geologic datasets for weights of evidence analysis in northeast Washington: 1. Geologic raster data
David E. Boleneus, J. Douglas Causey
2000, Open-File Report 2000-495
This dataset contains the combination of geology data (geologic units, faults, folds, and dikes) from 6 1:100,000 scale digital coverages in eastern Washington (Chewelah, Colville, Omak, Oroville, Nespelem, Republic). The data was converted to an Arc grid in ArcView using the Spatial Analyst extension....

Characteristics of water-well yields in the Blue Ridge of Loudoun County, Virginia
David M. Sutphin, L.J. Drew, J.H. Schuenemeyer, W.C. Burton
2000, Open-File Report 2000-280
Mean yields and the numbers of wells drilled are presented for 35 rock types containing 4,115 wells in the Blue Ridge of Loudoun County, Virginia. Analysis of variance of the well yields shows that Harper's Formation phyllite and Catoctin Formation metabasalt have yields significantly different from those of other rock types. Preliminary variography has...

Determination of the effects of fine-grained sediment and other limiting variables on trout habitat for selected streams in Wisconsin
Barbara C. Scudder, J.W. Selbig, R.J. Waschbusch
2000, Open-File Report 2000-435
Two Habitat Suitability Index (HSI) models, developed by the U.S. Fish and Wildlife Service, were used to evaluate the effects of fine-grained (less than 2 millimeters) sediment on brook trout (Salvelinusfontinalis, Mitchill) and brown trout (Salmo trutta, Linnaeus) in 11 streams in west-central and southwestern Wisconsin. Our results indicated that...

2000, Open-File Report 2000-407
Gravity and aeromagnetic data provide insights into the subsurface lithology and structure of the Virgin River Depression (VRD) of Nevada, Utah, and Arizona. The gravity data indicate that the Quaternary and Tertiary sedimentary deposits hide a complex pre-Cenozoic surface. A north-northwest-trending basement ridge separates the Mesquite and Mormon basins, as...
