Abstract:: “Exempt wells” are water wells that are exempt from one or more permit or other requirements in seventeen western states. Important policy considerations underlie the exemption, and only Utah does not exempt any water uses. However, some have expressed concerns about exempt water wells and the impact of the exemptions...

Abstract:: 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 connected, perched aquifers that support groundwater dependent ecosystems at points of...

Abstract:: Oregon is perceived as a water rich state; however, as the 2001 Klamath Basin crisis demonstrated, Oregon is not immune to water conflict and problems. Due to its seasonal fluctuations in water availability and geographical variation, Oregon can be considered a water scarce state, with the majority of surface water...

Abstract:: In an effort to reduce suspended solids and organic carbon loading and to increase long-term groundwater recharge rates at Orange County Water District’s spreading basins, a pilot project was conducted to evaluate riverbed filtration as a technology to treat river water prior to groundwater recharge. A shallow under-channel lateral drain...

Abstract:: The McKenzie River serves as the sole source of drinking water for nearly 200,000 residents in Eugene, OR. The McKenzie River is also home to a number of threatened and endangered fish species. Whereas the majority of the upper watershed is forested, areas of rural development and agriculture occur along...

Abstract:: The Walla Walla basin lies in an arid region on the border of Eastern Washington and Oregon. A large portion of the area is devoted to agricultural production, relying on irrigation water diverted from the Walla Walla River and underlying aquifers occurring within Quaternary gravel and Mio-pliocene basalt formations. Heavy...

Creator:: La Marche, Jonathan L., Gates, Edward B., and Lite Jr., Kenneth E.
Abstract:: 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 Water Resources Department (OWRD) increased its stream gaging network from three to ten...

Creator:: Cavallaro, Jamison
Abstract:: Oregon’s largest metropolitan region, Greater Portland, is home to a diverse array of water utilities though few have sufficiently robust water reuse and conservation goals. In determining the most beneficial way to allocate water-related public goods and natural resource management services, Oregonians are adapting to stronger legal standards among other...

Creator:: Steele, Madeline, Bonak, Zoe, and Chang, Heejun
Abstract:: While the negative effects of urban development on freshwater systems are well documented, impacts of human disturbance on water quality vary depending on land cover, local climate, and temporal and spatial scales of analysis. To better understand this variation, we analyzed water quality data for a total of 15 sites...

Abstract:: 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 snowmelt all affect streamflow. The response to these climate impacts includes earlier runoff peaks,...
