Erin Poor is a hydrologist at the USGS Oregon Water Science Center.
Currently operate multiple long-term, continuous water-quality sites. Responsibilities incl. maintaining and calibrating water-quality equipment, processing data to ensure USGS high-quality standards, and interpreting patterns and trends to better understand instream processes. Coordinate and participate in suspended-sediment sampling efforts during storm-events. Manage and participate in temperature synoptic(s) assessing spatial variability in surface-water temperature in urban ponds. Investigate spatial and temporal temperature and streamflow variation in beaver-effected stream reaches. Collect and process discrete water-quality data, incl. sampling for the National Water-Quality Assessment Program using parts-per-billion protocols; gaging continuous surface water and groundwater data; and measuring bathymetric and surface elevation data using both total station and real-time kinematic (RTK) instruments.

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
Water 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
