Oregon Water Science Center

Welcome to the USGS in Oregon. Our mission is to explore the natural world around us and provide reliable scientific information to help Federal, State, and local agencies, Tribes, and the public make well-informed decisions. Our research is widely used to manage Oregon's water resources for the benefit and safety of people and the environment.

Implications of water, sediment, and nutrient budgets for the restoration of a shallow, turbid lake in semiarid southeastern Oregon

Malheur Lake is the largest lake in the endorheic Harney Basin in southeastern Oregon. Since the 1990s, Malheur Lake—which averages depths of about 1 meter—has been in a degraded, turbid state lacking submergent and emergent vegetation. The goals of this study were to identify the major sources of sediment and nutrients to Malheur Lake to determine the importance of managing nutrients for lake res

Updates to CE-QUAL-W2 models for select U.S. Army Corps of Engineers reservoirs in the Willamette Valley Project and an inter-reservoir reach of the Middle Fork Willamette River, northwestern Oregon

Mechanistic models capable of simulating hydrodynamics and water temperature in rivers and reservoirs are valuable tools for investigating thermal conditions and their relation to dam operations and streamflow in river basins where upstream water storage and management decisions have an important influence on river reaches with threatened fish populations. In particular, models allow managers to i

Modeling the water-quality effects to the Klamath River from recirculation in drains and canals, Oregon and California, 2006–15

The potential recirculation of Klamath Strait Drain (hereafter called by its local name, “Klamath Straits Drain”) water into Ady Canal to reduce the drain discharge of high nutrient loads into the Klamath River was assessed by the U.S. Geological Survey for the Bureau of Reclamation. To study the feasibility of recirculation, this investigation evaluated three recirculation scenarios over a 10-yea

Multiscale comparison of hyperspectral reflectance from periphyton in three Oregon rivers used for municipal supply

In this study, USGS scientists from multiple centers used advanced hyperspectral imaging techniques to advance monitoring of attached benthic algae (periphyton) in Cascade Range rivers used for municipal water supply. Periphyton are naturally occurring, but excess growth can harm ecosystems and degrade raw and treated drinking water quality. In these rivers, periphyton contain cyanobacteria that...

Estimating Groundwater Budgets for Oregon

Scientists Stephen Gingerich and Adel Haj, Jr. are leading efforts to estimate groundwater budgets across the state. Water hidden beneath the earth’s surface is a vital resource and quantifying its availability is crucial for long-term management. USGS scientists are collaborating with scientists at the Oregon Water Resources Department to gain a better understanding of this valuable resource.

Klamath Dam Removal Studies

Following the removal of four dams along the Klamath River, more naturally dynamic flow conditions may result in novel water quality, sediment transport, and geomorphic conditions leading to temporary or longer-term ecological impacts. USGS continuous and discrete monitoring data on aspects related to sediment and geomorphic conditions will be integral to post-dam removal assessments and...
