Irrigated agriculture, energy, and endangered species in the Upper Klamath Basin : Evaluating trade-offs and interconnections

Creator:: Boehlert, Brent B.
Abstract:: In 2001, an extreme drought tightened water supply in the Upper Klamath Basin (basin) while earlier increases in Endangered Species Act (ESA) water requirements for basin fish species that same year elevated demands. The Bureau of Reclamation (Reclamation), which manages irrigation water in parts of the basin located near the...

Introducing geographic information systems to grass seed growers in the Willamette Valley of Oregon

Creator:: Hedstrom, Keldah E.
Abstract:: Oregon is the number one producer of cool-season grass seed in the United States. The center of the grass seed industry of Oregon is located in the Willamette Valley, where about 470,000 acres of seed are grown. Innovative grass seed growers of the area are beginning to implement precision agriculture...

The willingness of Central Oregon irrigators to donate water rights to augment Deschutes River flow

Creator:: Barkley, David, 1972-
Abstract:: This study used contingent valuation techniques to estimate the willingness of central Oregon Irrigators to donate a portion of their water rights to increase Deschutes River flow. This study was different from previous contingent valuation studies in that it used water rights as the payment vehicles instead of dollars -...

Hedonic price analysis to reveal value of water in irrigation : an application to northern Malheur County, Oregon

Creator:: Faux, John
Abstract:: Increasing water demand for growing municipalities, for water-based recreation and for fishery and wildlife habitat has intensified pressure on the existing resource. Reallocation of water from existing uses to other, higher-valued uses is receiving greater attention due to constraints on development of new water supplies. A key to reallocation is...

Improving nitrogen management with cover crops in organic broccoli production

Creator:: Garrett, Amy
Abstract:: Legume cover crops can serve as important sources of nitrogen (N) in sustainable agriculture and can be economically beneficial when fertilizer inputs are reduced without a yield reduction. Synchronizing N mineralization from organic materials with the needs of the subsequent crop is a challenge for organic growers. Predicting plant available...

Basin-wide distributed modeling of hydrologic responses to irrigation management in the Wood River Basin, Klamath County, OR

Creator:: Owens, Joshua M.
Abstract:: The Wood River Basin lies upstream of Upper Klamath Lake, the main reservoir of the USBR Klamath Irrigation Project that provides irrigation water to 210,000 acres of downstream land. Water allocation became a contentious issue in 2001 when drought led to curtailment of irrigation deliveries to the Klamath Irrigation Project...

A farm-level economic analysis of water-conserving irrigation systems and commercial agricultural water transfers to instream flows in central Oregon

Creator:: Turner, Brenda
Abstract:: The middle Deschutes River between Bend, Oregon and Lake Billy Chinook typically experiences critically low flows during the irrigation season. Commercial agriculture in the North Unit Irrigation District and Central Oregon Irrigation District is one major user of Deschutes River water. The overall objective of this research was to estimate...

Economic evaluation of different cropping patterns under irrigated agriculture : a multidisciplinary approach

Creator:: Mahrouf, Abdul R. M.
Abstract:: The purpose of this study is to determine the socioeconomic factors which influence the profitability and adoption of new cropping patterns, and to recommend suitable measures to enhance the crop diversification program in Mahaweli System B, Sri Lanka. The adoption of new cropping patterns is determined by a number of...

The effects of farm and operator characteristics, knowledge, and attitudes on farm-level improvements in irrigation efficiency in the central Willamette Valley

Creator:: Stoff, Mary Cora
Abstract:: A study was conducted using data collected from a sample of mint and vegetable farmers in the Willamette Valley of Oregon. The study identifies the influence of demographic differences, economic factors and irrigator attitudes on irrigation efficiency. Only two of the 19 characteristics theorized to influence irrigation efficiency proved to...
