Biography
Dan is a hydrologist with the U.S. Geological Survey at the Oregon Water Science Center in Portland, Oregon. He received a B.S. in Civil and Environmental Engineering from Drexel University in 1990, an M.S. in Civil and Environmental Engineering from the University of Rhode Island in 1993, and an M.S. in Geography from Oregon State University in 2001. He has been with the USGS since 2001.
Dan's work is focused primarily on the interpretation of regional water quality data. His current research focuses on relating surface-water nutrient and sediment conditions to landscape characteristics using the USGS SPARROW model (Spatially Referenced Regressions on Watershed Attributes).

SPARROW Model Assessments of Nutrients and Suspended Sediment in the Pacific Northwest and California
SPARROW can be used to relate water-quality data to landscape characteristics, such as natural properties and human activities
Changing climate drives future streamflow declines and challenges in meeting water demand across the southwestern United States
Society and the environment in the arid southwestern United States depend on reliable water availability, yet current water use outpaces supply. Water demand is projected to grow in the future and climate change is expected to reduce supply. To adapt, water managers need robust estimates of future regional water supply to support management...

Spatially referenced models of streamflow and nitrogen, phosphorus, and suspended-sediment loads in streams of the Pacific region of the United States
Although spatial information describing the supply and quality of surface water is critical for managing water resources for human uses and for ecological health, monitoring is expensive and cannot typically be done over large scales or in all streams or waterbodies. To address the need for such data, the U.S. Geological Survey developed SPAtially...

Spatially referenced models of streamflow and nitrogen, phosphorus, and suspended-sediment transport in streams of the southwestern United States
Given the predicted imbalance between water supply and demand in the Southwest region of the United States, and the widespread problems with excessive nutrients and suspended sediment, there is a growing need to quantify current streamflow and water quality conditions throughout the region. Furthermore, current monitoring stations exist at a...

Updates to the suspended sediment SPARROW model developed for western Oregon and northeastern California
A SPARROW (SPAtially Related Regressions On Watershed attributes) model that was previously developed for western Oregon and northwestern California was updated using advancements in the SPARROW software and refinements to the input data. As was the case for the original model calibration, the updated models used the NHD Plus Version 2 as a...

A spatially explicit suspended-sediment load model for western Oregon
We calibrated the watershed model SPARROW (Spatially Referenced Regressions on Watershed attributes) to give estimates of suspended-sediment loads for western Oregon and parts of northwestern California. Estimates of suspended-sediment loads were derived from a nonlinear least squares regression that related explanatory variables representing...
Wise, Daniel R.; O'Connor, Jim Water supply, demand, and quality indicators for assessing the spatial distribution of water resource vulnerability in the Columbia River Basin
We investigated water resource vulnerability in the US portion of the Columbia River basin (CRB) using multiple indicators representing water supply, water demand, and water quality. Based on the US county scale, spatial analysis was conducted using various biophysical and socio-economic indicators that control water vulnerability. Water supply...

Application of the SPARROW model to assess surface-water nutrient conditions and sources in the United States Pacific Northwest
The watershed model SPARROW (Spatially Referenced Regressions on Watershed attributes) was used to estimate mean annual surface-water nutrient conditions (total nitrogen and total phosphorus) and to identify important nutrient sources in catchments of the Pacific Northwest region of the United States for 2002. Model-estimated nutrient yields were...
Wise, Daniel R.; Johnson, Henry M. Surface-water nutrient conditions and sources in the United States Pacific Northwest
The SPAtially Referenced Regressions On Watershed attributes (SPARROW) model was used to perform an assessment of surface-water nutrient conditions and to identify important nutrient sources in watersheds of the Pacific Northwest region of the United States (U.S.) for the year 2002. Our models included variables representing nutrient sources as...

Assessment of Eutrophication in the Lower Yakima River Basin, Washington, 2004-07
In response to concerns that excessive plant growth in the lower Yakima River in south-central Washington was degrading water quality and affecting recreational use, the U.S. Geological Survey and the South Yakima Conservation District conducted an assessment of eutrophication in the lower 116 miles of the river during the 2004-07 irrigation...

Nutrient and Suspended-Sediment Transport and Trends in the Columbia River and Puget Sound Basins, 1993-2003
This study focused on three areas that might be of interest to water-quality managers in the Pacific Northwest: (1) annual loads of total nitrogen (TN), total phosphorus (TP) and suspended sediment (SS) transported through the Columbia River and Puget Sound Basins, (2) annual yields of TN, TP, and SS relative to differences in landscape and...

Water Quality in the Yakima River Basin, Washington, 1999-2000
This report contains the major findings of a 1999?2000 assessment of water quality in streams and drains in the Yakima River Basin. It is one of a series of reports by the NAWQA Program that present major findings on water resources in 51 major river basins and aquifer systems across the Nation. In these reports, water quality is assessed...

SPARROW modeling: Estimating contaminant transport
What’s New: A new version of the SPARROW code is being developed in the R programming language. The advantage of R is that it is non-proprietary and does not require a license or software cost. The R – SPARROW code is now being completed and should be available early in CY18. Stay Tuned.
Surface-water nutrient and sediment mappers are now available
SPARROW mappers are interactive tools that allow users to evaluate streamflow and nutrient and sediment conditions as well as the importance of different sources of contaminants in a selected river basin. Data can be visualized at different scales using maps and interactive graphs and tables.
