Wood River Valley Hydrologic Trends and Comparisons

Wood River Valley residents rely on groundwater for domestic supply, either from domestic or municipal-supply wells. The rapid population growth since the 1970s has caused concern about the long-term sustainability of the groundwater resource.

Effects of Nutrient Enrichment on Stream Ecosystems (Upper Snake River Basin NAWQA)

Nutrient enrichment can affect the ecological health of a stream. For example, excessive aquatic plant growth caused by increased nutrients can reduce dissolved oxygen necessary for other aquatic life. Topics of particular interest in this study area include:

seasonal patterns among nutrients, flows, algae and plants in streams

rooted aquatic plant vs. algae growth

Debris-Flow Hazard Assessment of the Area Burned by the 2013 Beaver Creek Fire

In August 2013, the Beaver Creek wildfire burned more than 100,000 acres of public and private land northwest of Hailey, Idaho. According to the U.S. Forest Service, about 57 percent of the area is considered moderately burned, and the risk of post-fire soil erosion is high on more than 8,400 acres.

Sediment Sampling in the Snake and Clearwater River Basins

Are there ways to manage sediment before it accumulates in Lower Granite Reservoir? If so, resource managers must know exactly how much sediment is being transported in the lower Snake and Clearwater River basins, the grain-size distribution of the sediment that is being transported, which subbasins are contributing the most sediment, and how the sediment is being deposited once it is...

Erosion and Invasive Saltcedar

Formation of arroyos in the late 1800s greatly increased erosion across the southwestern United States. Since the 1930s, however, this erosion has decreased, partly because of bank stabilization by introduced saltcedar. With Isleta Pueblo Indian Nation, the Aquatic Systems Branch developed a new sediment dating method using saltcedar tree rings. We applied the method in a landmark study of...

Economics and Ecosystem Services

Federal policymakers and land managers are accountable to the public for how they invest public funds and for the outcomes of the policy and management decisions they make. Through a variety of economic analyses and custom modeling, SEA economists evaluate how investments and management decisions affect individuals, local communities, and society as a whole.

Structure maps of the Carrizo-Wilcox aquifer in northwestern Louisiana

Groundwater resources in northwestern Louisiana may be needed for development of natural gas production from the Haynesville Shale. Use of groundwater for hydro-fracturing of the shale may lower water levels and alter groundwater flow directions in the Carrizo-Wilcox aquifer and other local aquifers. Regional maps of aquifers in northwestern Louisiana are unavailable. The LaWSC, in cooperation...

Water Use Trends in Alabama

Since 1950 when the U.S. Geological Survey (USGS) first conducted water-use compilations, important changes in water use have occurred in Alabama. The early part of the history (1950 to 1980) showed a steady increase in water use. During this time, the expectation was that, as the population increased, so would water use. Contrary to this expectation, reported water withdrawals declined in...

Late Quaternary environmental dynamics in the Atacama Desert reconstructed from rodent midden pollen records

In the past two decades, much has been learned about the late Quaternary climate history of the Atacama Desert with some details still unclear about the seasonality, timing and extent of wet and dry phases. Modern climate studies reveal that, far from exhibiting a unique pattern, seasonal precipitation originates from many sources and mechanisms....

Detection of diazotrophy in the acetylene-fermenting anaerobe Pelobacter sp. strain SFB93

Acetylene (C2H2) is a trace constituent of the present Earth's oxidizing atmosphere, reflecting a mixture of terrestrial and marine emissions from anthropogenic, biomass-burning, and unidentified biogenic sources. Fermentation of acetylene was serendipitously discovered during C2H2 block assays of N2O reductase, and Pelobacter acetylenicus was...

Autotrophic microbial arsenotrophy in arsenic-rich soda lakes

A number of prokaryotes are capable of employing arsenic oxy-anions as either electron acceptors [arsenate; As(V)] or electron donors [arsenite; As(III)] to sustain arsenic-dependent growth (‘arsenotrophy’). A subset of these microorganisms function as either chemoautotrophs or photoautotrophs, whereby they gain sufficient energy from their redox...

Storage filters upland suspended sediment signals delivered from watersheds

Climate change, tectonics, and humans create long- and short-term temporal variations in the supply of suspended sediment to rivers. These signals, generated in upland erosional areas, are filtered by alluvial storage before reaching the basin outlet.
