AbstractAbstract
[en] This paper describes an object-oriented approach to river basin simulation modeling that is event driven rather than time driven as are most river system simulation models. At the heart of this method are autonomous software objects which replicate the physical behavior of the components of an actual river system (Colorado River). These objects react to stimuli (changing values of their inputs, outputs or state) in much the same way as do the analogous components of the actual river. The simulation of river systems is the result of the coordinated actions, in any order, of the various objects representing the entities within the system. An object-oriented approach to modeling a river has a number of characteristics that make it worthy of consideration. The model's architecture makes it especially suited to graphic user interfaces and database operations. It allows the easy integration of artificial intelligence techniques that can aid in expressing complex policies governing system operation

AbstractAbstract
[en] This study attempts to identify and analyze the impacts of the System Operating Strategy (SOS) alternatives on cultural resources. The impacts include effects on Native American traditional cultural values, properties and practices. They also include effects on archeological or historic properties meeting the criteria of the National Register of Historic Places. In addition to responding to the requirements of the National Environmental Policy Act (NEPA), this analysis addresses the requirements of the National Historic Preservation Act (NHPA), the Archeological Resources Protection Act (ARPA), the Native American Graves Protection and Repatriation Act (NAGPRA), the Native American Religious Freedom Act (NARFA), and other relevant legislation. To meet their legally mandated cultural resources requirements, the SOR agencies will develop agreements and Implementation Plans with the appropriate State Historic Preservation Officers (SHPOs), Tribes, and the Advisory Council on Historic Preservation (ACHP) detailing the measures necessary to best manage the resource. The planning and implementation activities will be staged over a number of years in consultation with affected Tribes

AbstractAbstract
[en] An attempt was made to determine the extent to which northern squawfish predation on juvenile salmonids is a problem in the Columbia River Basin, and to evaluate how effectively fisheries can be used to control northern squawfish populations and reduce juvenile salmonid losses to predation. These studies were initiated as part of a basinwide program to control northern squawfish predation and reduce mortality of juvenile salmonids on their migration to the ocean. Modeling simulations based on work in the John Day Reservoir from 1982 through 1988 indicated that if northern squawfish larger than 250 mm fork length were exploited, at a rate of 10-20%, reductions in their numbers and restructuring of their populations could reduce their predation on juvenile salmonids by 50% or more. The authors evaluated the success of three test fisheries conducted in 1993-a sport-reward fishery, a dam-angling fishery, and a trap-net fishery, to achieve a 10-20% exploitation rate on northern squawfish . The authors also began evaluating the response of northern squawfish populations to sustained fisheries. In addition, the authors gathered information regarding the economic, social, and legal feasibility of sustaining each fishery, and report on the structure and function of the fish collection and distribution system

AbstractAbstract
[en] Rice irrigation is the largest user of water within the area served by the Lower Colorado River Authority (LCRA), accounting for approximately 75 percent of total annual surface and ground water demands. In an average year, about 30 percent of surface water supplied to rice irrigation is satisfied with water released from the storage in the Highland Lakes located at the upstream reaches of the Lower Colorado River and its tributaries. During a severe drought, the demand for stored water could be as much as 70 percent of annual rice irrigation demand. LCRA owns and operates two irrigation canal systems which together supply water to irrigate 60,000 acres of rice each year. These irrigation systems are the Lakeside and Gulf Coast Irrigation Divisions. The Lakeside system is located in Colorado and Wharton Counties and the Gulf Coast system is located in Wharton and Matagorda Counties. In the 1987 and 1989, the Lower Colorado River Authority Board of Directors authorized implementation and funding for Canal Rehabilitation Project and Irrigation Water Measurement Project respectively. These two projects are key initiatives to agricultural water conservation goals established in the LCRA Water Management Plan and Water Conservation Policy. In addition LCRA participated actively in agricultural water conservation research projects and technology transfer activities

AbstractAbstract
[en] The primary objective of the study was to increase the number of summer steelhead (Oncorhynchus mykiss) from Dworshak National Fish Hatchery that outmigrate by promoting smoltification in a larger proportion of the production release. To achieve this goal, growth was reduced during the winter to produce a smaller size range of fish to eliminate the production of large fish that residualize. A period of accelerated growth prior to release was designed to promote smoltification in all fish, regardless of size. Decreased winter growth was achieved with a combination of reduced ration and short, intermittent feeding periods. Growth rates were not reduced to the expected level in the modified feeding schedule treatment group, control group, or general production fish reared in the same system. Although significant differences in length, weight and condition factor developed between treatment and control groups during December and January, compensatory growth of the treatment fish after return to full rations resulted in fish of the same size from both groups for release. Migration rates of the treatment group were higher than that of the control group, although the difference was not significant. Growth and survival during extended seawater rearing did not differ between the two groups. Smoltification, as measured by gill Na+, K+-ATPase and seawater survival, were unaffected by a reduction in feed during winter months. This study demonstrates the application of hatchery specific performance and holding condition records to develop a reduced ration, intermittent feeding method to modulate growth with no negative effects on smolt development. Future trials of reduced ration, intermittent feeding methods may be refined from this study to test the method during different rearing stages. The modified feeding schedule should be extended to produce a smaller size range of fish

AbstractAbstract
[en] The Columbia River System is a vast and complex combination of Federal and non-Federal facilities used for many purposes including power production, irrigation, navigation, flood control, recreation, fish and wildlife habitat and municipal and industrial water supply. Each river use competes for the limited water resources in the Columbia River Basin. This technical appendix addresses only the effects of alternative system operating strategies for managing the Columbia River system. The environmental impact statement (EIS) itself and some of the other appendices present analyses of the alternative approaches to the other three decisions considered as part of the SOR. This document is the product of the Wildlife Work Group, focusing on wildlife impacts but not including fishes. Topics covered include the following: scope and process; existing and affected environment, including specific discussion of 18 projects in the Columbia river basin. Analysis, evaluation, and alternatives are presented for all projects. System wide impacts to wildlife are also included
