Casie Smith is an ecologist at the USGS Oregon Water Science Center who works in Bend, Oregon.
Recent projects involve:
-monitoring linkages between water availability, water quality, and productivity in terminal lakes of the Great Basin,
-developing a decision-support tool to optimize water allocations and habitat management on federal lands,
-assessing restoration scenarios for a degraded lake to inform resource management, and
-evaluating the fate and transport of contaminants in aquatic systems and drinking water.

Spatial Water-Quality Measurements in Willow Creek Reservoir located in Heppner, Oregon, 2015-2016 Spatial Water-Quality Measurements in Willow Creek Reservoir located in Heppner, Oregon, 2015-2016
High frequency water-quality measurements were collected by the U.S. Geological Survey within Willow Creek Reservoir located in Heppner, Oregon. All measurements were taken at 1.5 feet below the surface with a YSI EXO2 multiparameter sonde. Information collected include location, time, water temperature, pH, specific conductance, dissolved oxygen, total chlorophyll, blue-green algae...
A Baseline Assessment of Contaminant Concentrations in Sediment and Biota in Proximity to Coal Transport Tracks in the Pacific Northwest (2014) A Baseline Assessment of Contaminant Concentrations in Sediment and Biota in Proximity to Coal Transport Tracks in the Pacific Northwest (2014)
This dataset provides baseline concentrations (from 2014) of polycyclic aromatic hydrocarbon (PAH), other aromatic organic compounds, mercury (Hg), and trace metal concentrations in sediment and biota collected from two sites along an existing rail line used for coal transport in the Columbia River Gorge, Washington. For this study, aquatic surface sediments, aquatic insects, and...
Beaver dam locations and beaver activity in the Tualatin Basin, Oregon, between 2013 and 2016 Beaver dam locations and beaver activity in the Tualatin Basin, Oregon, between 2013 and 2016
USGS met with 13 local groups and organizations around the Portland, Oregon region to collect information regarding the locations of beaver dams in the Tualatin Basin. The local sources had identified beaver dams between 2013 and 2016, and data were compiled by USGS into an ArcGIS shapefile. Often, the local groups did not know the GPS coordinates of beaver dams, but they had identified...
Point measurements of temperature and water quality in main-channel and off-channel features of the Willamette River, 2015-2016 Point measurements of temperature and water quality in main-channel and off-channel features of the Willamette River, 2015-2016
Water quality point measurements were collected by the US Geological Survey within the main channel Willamette River and its off-channel features in the summer and autumn of 2015 and 2016. All measurements include location, time, temperature, and depth below water surface, while most also include specific conductivity, dissolved oxygen, and pH.

Temperature and water-quality diversity and the effects of surface-water connection in off-channel features of the Willamette River, Oregon, 2015–16 Temperature and water-quality diversity and the effects of surface-water connection in off-channel features of the Willamette River, Oregon, 2015–16
Water-quality conditions (including temperature) in the Willamette River and many of its adjacent off-channel features, such as alcoves and side channels, were monitored between river miles 67 (near Salem, Oregon) and 168 (near Eugene, Oregon) during the summers of 2015 and 2016. One or more parameters (water temperature, dissolved oxygen, pH, specific conductance, and [or] water depth)...

Evaluation of restoration alternatives using water-budget tools for the Wapato Lake National Wildlife Refuge, northwestern Oregon Evaluation of restoration alternatives using water-budget tools for the Wapato Lake National Wildlife Refuge, northwestern Oregon
The lakebed in Wapato Lake National Wildlife Refuge (NWR) in northwestern Oregon was farmed for decades prior to the establishment of the refuge in 2013. Planning for restoration of these lands required extensive data collection and construction of a water budget and tools to design and evaluate potential restoration strategies. The U.S. Geological Survey (USGS) and U.S. Fish and...

Contaminant concentrations in sediments, aquatic invertebrates, and fish in proximity to rail tracks used for coal transport in the Pacific Northwest: A baseline assessment Contaminant concentrations in sediments, aquatic invertebrates, and fish in proximity to rail tracks used for coal transport in the Pacific Northwest: A baseline assessment
Railway transport of coal poses an environmental risk because coal dust contains polycyclic aromatic hydrocarbons (PAHs), mercury (Hg), and other trace metals. In the Pacific Northwest, proposed infrastructure projects could result in an increase in coal transport by train through the Columbia River corridor. Baseline information is needed on current distributions, levels, and spatial...

Temporal and spatial monitoring of cyanobacterial blooms at Willow Creek Reservoir, North-Central Oregon Temporal and spatial monitoring of cyanobacterial blooms at Willow Creek Reservoir, North-Central Oregon
The U.S. Geological Survey (USGS) and U.S. Army Corps of Engineers (USACE) investigated the spatial and temporal dynamics of cyanobacterial (blue-green algal) blooms in Willow Creek Reservoir in north-central Oregon in 2015–16. A combination of cameras and water-quality monitoring equipment was used to assess the frequency and duration of blooms and their effects on water quality. A...

Klamath River Basin water-quality data Klamath River Basin water-quality data
The Klamath River Basin stretches from the mountains and inland basins of south-central Oregon and northern California to the Pacific Ocean, spanning multiple climatic regions and encompassing a variety of ecosystems. Water quantity and water quality are important topics in the basin, because water is a critical resource for farming and municipal use, power generation, and for the...
