Chauncey Anderson
Welcome to the Staff Profile for Chauncey Anderson, Hydrologist and Water Quality Specialist at USGS Oregon Water Science Center in Portland, Oregon.
Chauncey Anderson is a Hydrologist and Water Quality Specialist for the USGS Oregon Water Science Center (ORWSC), where he has worked since 1991. He studies the effects of land and water management on aquatic resources; primarily water quality, sediment, and ecosystem responses, in Oregon and nationally. He has worked extensively around the hydrologic impacts of reservoir operations. In 2009-2013, he was Co-Chair of the Water Quality Subteam for the Secretarial Determination on the Klamath Hydroelectric Settlement Agreement, and currently works on other Klamath Basin issues. Since 2000 he has also studied hydrologic and water quality effects on amphibians as part of USGS's Amphibian Research and Monitoring Initiative, or ARMI. He is the author of the USGS' national protocol on measurement of turbidity in water, which led him to work on the use of turbidity and other continuously measured surrogates to estimate real-time concentrations of suspended sediment and other constituents in water.

Preliminary assessment of vertical stability and gravel transport along the Umpqua River, southwestern Oregon
This report addresses physical channel issues related to instream gravel mining on the Umpqua River and its two primary tributaries, the North and South Umpqua Rivers. This analysis constitutes a “Phase I” investigation, as designated by an interagency team cochaired by the U.S. Army Corps of Engineers, Portland District, and the Oregon Department of State Lands to address instream gravel mining iAuthorsJim E. O'Connor, J. Rose Wallick, Steven Sobieszczyk, Charles Cannon, Scott W. AndersonShort-term effect of cattle exclosures on Columbia Spotted Frog (Rana luteiventris) populations and habitat in northeastern Oregon
Livestock grazing is a common land use across the western United States, but concerns have been raised regarding its potential to affect amphibian populations. We studied the short-term effects of full and partial livestock grazing exclosures on Rana luteiventris (Columbia Spotted Frog) populations using a controlled manipulative field experiment with pre- and posttreatment data (2002–2006).

KuehlDistribution limits of Batrachochytrium dendrobatidis: a case study in the Rocky Mountains, USA
Knowledge of the environmental constraints on a pathogen is critical to predicting its dynamics and effects on populations. Batrachochytrium dendrobatidis (Bd), an aquatic fungus that has been linked with widespread amphibian declines, is ubiquitous in the Rocky Mountains. As part of assessing the distribution limits of Bd in our study area, we sampled the water column and sediments for Bd zoosporAuthorsBlake R. Hossack, Erin L. Muths, Chauncey W. Anderson, Julie D.

A temporary, 14‐meter‐high earthen cofferdam standing in place of Marmot Dam was breached on 19 October 2007, allowing the 80‐ kilometer‐long Sandy River to flow freely from Mount Hood, Oreg., to the Columbia River for the first time in nearly 100 years. Marmot Dam is one of the largest dams in the western United States (in terms of height and volume of stored sediment) to have been removed in theAuthorsJon J. Major, Kurt R. Spicer, Abagail Rhode, J.

GrantInfluence of Cougar Reservoir Drawdown on Sediment and DDT Transport and Deposition in the McKenzie River Basin, Oregon, Water Years 2002-04
Construction of a selective withdrawal tower at Cougar Reservoir in the South Fork McKenzie River, Oregon, during 2002-05 resulted in a prolonged release of sediment and high-turbidity water to downstream reaches throughout the summer of 2002, with additional episodic releases during storms in the following winters. Suspended-sediment concentrations and loads at five continuously monitored turbidiAuthorsChauncey W. AndersonQuantitative PCR detection of Batrachochytrium dendrobatidis DNA from sediments and water
The fungal pathogen Batrachochytrium dendrobatidis (Bd) causes chytridiomycosis, a disease implicated in amphibian declines on 5 continents. Polymerase chain reaction (PCR) primer sets exist with which amphibians can be tested for this disease, and advances in sampling techniques allow non-invasive testing of animals. We developed filtering and PCR based quantitative methods by modifying existingAuthorsJulie D. Kirshtein, Chauncey W. Anderson, J.S. Wood, Joyce E. Longcore, Mary A. VoytekWater Quality and Algal Data for the North Umpqua River Basin, Oregon, 2005
The upper North Umpqua River Basin has experienced a variety of water-quality problems since at least the early 1990's. Several reaches of the North Umpqua River are listed as water-quality limited under section 303(d) of the Clean Water Act. Diamond Lake, a eutrophic lake that is an important source of water and nutrients to the upper North Umpqua River, is also listed as a water-quality limitedAuthorsDwight Q. Tanner, Andrew J. Arnsberg, Chauncey W. Anderson, Kurt D. CarpenterChapter A6. Section 6.7. Turbidity
Turbidity is one of the indicators used to assess the environmental health of water bodies. Turbidity is caused by the presence of suspended and dissolved matter, such as clay, silt, finely divided organic matter, plankton and other microscopic organisms, organic acids, and dyes. This section of the National Field Manual (NFM) describes the USGS protocols for determining turbidity in surface and gAuthorsChauncey W.

Fertilization of forests with urea-nitrogen has been studied numerous times for its effects on water quality. Stream nitrogen concentrations following fertilization are typically elevated during winter, including peaks in the tens-of-thousands of parts per billion range, with summer concentrations often returning to background or near-background levels. Despite these increases, water-quality criteAuthorsChauncey W. AndersonFramework for Regional, Coordinated Monitoring in the Middle and Upper Deschutes River Basins, Oregon
This report presents a framework for regional water-quality monitoring in the middle and upper Deschutes River Basin, Oregon, that would be coordinated among organizations doing related monitoring. The emphasis is on maximizing the value of existing programs and resources by minimizing overlapping sampling efforts, filling key data gaps, increasing communication about results, and facilitating cooAuthorsChauncey W.

We analyzed available concentration data of five commonly used herbicides and three pesticides collected from small streams in the Willamette River Basin in Oregon to identify factors that affect the variation of their concentrations in the area. The emphasis of this paper is the innovative use of classification and regression tree models for exploratory data analysis as well as analyzing data witAuthorsS.S. Qian, Chauncey W. Anderson - News
