Climate Change: Natural Variability is a Big Deal Too!
Climate changes. That’s what climate does. It is a natural and dynamic process. The National Weather Service (NWS) recognizes on-going climate change by publishing new figures for average climate every ten years. Climate averages for... 24-May-2011 (iso8601)

How Much Groundwater does a Wetland Need? Setting Ecological Water Requirements for...
Many freshwater ecosystems are sustained by a continuous supply of clean groundwater. For example, groundwater may provide late season baseflow to rivers or a sustained high water table in wetlands. These ecosystems, termed GDEs, often are... 24-May-2011 (iso8601)

Hydrologic Monitoring and Trends in the Upper Klamath Basin over the Last Decade
Over the last decade hydrologic monitoring efforts in the Upper Klamath Basin (UKB) of Oregon have increased in response to the continued strain on surface water and groundwater to meet competing biological and agricultural demands. The Oregon... 24-May-2011 (iso8601)

Assessing Streamflow Response to Climate Change: Why Geology Matters
Climate change will continue to profoundly affect water supply and aquatic ecosystems in the Pacific Northwest. Changes such as warmer air temperatures, increases in the proportion of winter rain versus snow, reduced spring snowpack, and earlier... 24-May-2011 (iso8601)

What Will Oregon’s Future Streamflow Regimes Look Like? Integrating Snowpack and...
Spatial patterns of summer streamflow in the Cascade Mountains of Oregon vary dramatically between the geologically distinct High and Western Cascade regions. A key control is the partitioning of water input between a fast-draining shallow... 24-May-2011 (iso8601)

Sensitivity of Oregon Watersheds to Streamflow Changes Due to Climate Warming: A...
A key challenge for resource and landscape managers is to predict the consequences of climate warming on streamflows and water resources. Different approaches are being developed to forecast the direction, magnitude, and timing of future... 24-May-2011 (iso8601)

Groundwater Storage and Flow in an Unconfined Pumice Aquifer, Antelope Unit, Chemult...
The study area lies north-northeast of Crater Lake National Park and is covered by 2 to 3 m of pumice deposited during the climactic eruption of Mount Mazama approximately 7700 years before present. The pumice deposit hosts unconfined, seasonally... 24-May-2011 (iso8601)

Surface Water Interaction with “Confined” Columbia River Basalt Aquifers – Impacts to...
Columbia River Basalt Group (CRBG) aquifers are commonly thought to be relatively flat lying, laterally extensive, and mostly confined, and therefore not likely to be directly connected to surface water. However, many of the CRBG units in... 24-May-2011 (iso8601)

Assessment of Climate Change Impacts on Drought Return Periods Using Copula Functions
Drought events are usually characterized by their duration, severity, and intensity which are calculated based on different indices for drought recognition. Streamflow Drought Index (SDI) used in hydrological droughts is applied in this study to... 24-May-2011 (iso8601)

Assessment of the Hydrologic Response to Climate Change in the Upper Deschutes River...
Effects of climate change in the Cascade Range will likely include more rain, less snow, and earlier snowmelt in the Cascade Range as compared to present conditions. These changes, in turn, will affect the timing of runoff, groundwater recharge,... 24-May-2011 (iso8601)

Hydrologic Response to Climate Change in the Sprague River Basin, Oregon
In 2008 the U.S. Geological Survey began a Global Change study that evaluated the watershed scale response to climate change in selected basins across the United States. Fourteen basins for which the Precipitation Runoff Modeling System (PRMS) had... 24-May-2011 (iso8601)

Effects of Climate Change on Water Quality in the Yaquina Estuary, Oregon
As part of a larger study to examine the effect of climate change (CC) on estuarine resources, we simulated the effect of rising sea level, alterations in river discharge, and increasing atmospheric temperatures on water quality in the Yaquina... 24-May-2011 (iso8601)

Climate Change and Oregon’s Water Future
The specter of climate change looms large over Oregon. Although hydroclimatologic models predict a warmer Oregon, the total volume of precipitation may not change significantly. However, the character (rain vs. snow) and spatial and temporal... 24-May-2011 (iso8601)

Climate Change and Shifts in Water Related Ecosystem Services in the Tualatin and...
Water related ecosystem services (WES), such as flow regulation, drinking water supply, temperature regulation, and water recreational activities, are affected by anthropogenic climate change. Forecasting potential shifts in such WES is critical... 24-May-2011 (iso8601)

Climate Change Impact on Drought Risk and Uncertainty in the Willamette River Basin
Climate change due to global warming could induce more frequent droughts in the Willamette River Basin because less snowfall in winter and earlier snowmelt due to temperature increase may lead to decreases in spring and summer streamflow. This... 24-May-2011 (iso8601)

Oregon’s Integrated Water Resources Strategy (IWRS)
During 2009, the 75th Legislative Assembly passed House Bill 3369, directing the Oregon Water Resources Department to develop a state-wide, Integrated Water Resources Strategy (IWRS) to help Oregon meet its future water quantity, water quality,... 24-May-2011 (iso8601)
