Obtaining proper permits for construction and research purposes. Create project schedules and monitor status to ensure project goals are met. Plan and lead sampling teams. Review various long-term datasets to ensure high quality. Develop and maintain collaborative partnerships with federal, state and local government agencies along with non-profit organizations. Maintain consistent and clear communication with partners. Vision planning and proposal development and writing.
Data Management and Interpretation: Interpret patterns and trends in continuous water quality datasets to better understand instream processes. Calculate stream flashiness. Evaluate changes in stream response to storm events. Spatial analysis of discrete data using geographic information systems (GIS). Audit continuous water quality records to ensure the highest quality data.
Fieldwork: Operate multiple long-term, continuous water-quality sites. Responsibilities include maintaining and calibrating water-quality equipment, processing data to ensure high-quality standards. Coordinate and participate in suspended-sediment sampling efforts during storm-events for multiple projects. Manage and participate in temperature synoptics assessing spatial variability in surface-water temperature in urban ponds. Investigate spatial and temporal temperature and streamflow variation in beaver-effected stream reaches. Install and maintain continuous surface water and groundwater gaging stations.
Geographic Information System (GIS): Designed and created numerous maps for publications and presentations. Used GIS to assess spatial trends in water quality data, including water temperature, dissolved oxygen and sediment accumulation. Developed layers used to create boundaries for an office move using survey data for a weighted analysis.

Beavers and their dams can substantially change the storage and movement of water through a stream reach. The magnitude of this change is, in part, a function of the number and type of dams plus stream characteristics.

Beaver dams and associated ponding affect sediment transport and trapping by pushing water onto the floodplain and decreasing stream velocity, allowing for increased sediment deposition.

Beaver dams and ponds fundamentally alter how water moves through a stream reach. Semi-porous dams can impound water, leading to backwatering, floodplain inundation, and overall changes in wetted area, depth, and velocity.

Fernhill Natural Treatment Wetlands
The amount and type of algae in the Tualatin River affect the river’s water quality and ecological health, as well as its value as a recreational resource. As a relatively new source of summertime flow to the upper Tualatin River, discharges from the Fernhill Natural Treatment System (NTS) have the potential to enhance or degrade downstream water quality. Discharges of low nutrient concentrations...Johnson Creek Basin Hydrologic Monitoring Study
The USGS provides hydrologic data for the Johnson Creek Basin. Real-time surface-water, water-quality and groundwater data, as well as historic data and analyses, help to improve our understanding of the hydrology of the basin.Tualatin River Basin Water Quality Assessment
In 1990, the USGS began assessing water-quality in the Tualatin River. Almost 30 years later, we are still monitoring conditions in the basin.City Beavers: Tualatin River Basin Beaver Study
Beavers and their dams are common sights along creeks in the Tualatin River basin. Beaver help create diverse habitats for many other animals, including birds, fish, and amphibians. The USGS studying the affect beaver activity has on the amount and quality of water in local streams, so that agencies in the basin can make strategic management and habitat restoration decisions based on science. - Data
Plankton taxonomy and water quality in the Tualatin River Basin to the west of Portland, Oregon, during the summers of 2019-21
Water-quality data and plankton samples were collected at multiple locations within the Fernhill Natural Treatment wetland and along the Tualatin River, located to the west of Portland, Oregon, during the summers of 2018, 2019 and 2020. Water quality parameters collected include water temperature, specific conductance, dissolved oxygen, pH, turbidity, chlorophyll, and blue green algae. Data were cWater Temperature, Dissolved Oxygen, and pH Point Measurements from a Beaver Pond along Fanno Creek, Oregon, on four hot days in summers 2016-17
Water-quality point measurements were collected at various depths throughout a beaver pond along Fanno Creek in the Tualatin River Basin, Oregon. Parameters collected include water temperature, dissolved oxygen, and sometimes pH. All data were collected over a short period of time (< 4 hours) during 4 hot days in order to characterize the spatial (both horizontal and vertical) variability of these - Multimedia
