	Citation Citation Citation Abstract Copy Title: An assessment of ecosystem components in the interior Columbia Basin and portions of the Klamath and Great Basins [volume 1] Author: Quigley, Thomas Milton; Arbelbide, S. J. (Sylvia J.) Year: 1997, 2008, 2005 Quigley, Thomas M.; Arbelbide, Sylvia J., tech. eds. 1997. An assessment of ecosystem components in the interior Columbia basin and portions of the Klamath and Great Basins: volume 1. Gen. Tech. Rep. PNW-GTR-405. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 4 vol. (Quigley, Thomas M., tech. ed.; The Interior Columbia Basin Ecosystem Management Project: Scientific Assessment). The Assessment of Ecosystem Components in the Interior Columbia Basin and Portions of the Klamath and Great Basins provides detailed information about current conditions and trends for the biophysical and social systems within the Basin. This information can be used by land managers to develop broad land management goals and priorities and provides the context for decisions specific to smaller geographic areas. The Assessment area covers about 8 percent of the U.S. land area, 24 percent of the Nation's National Forest System lands, 10 percent of the Nation's BLM-administered lands, and contains about 1.2 percent of the Nation's population. This results in a population density that is less than one-sixth of the U.S. average. The area has experienced recent, rapid population growth and generally has a robust, diverse economy. As compared to historic conditions, the terrestrial, aquatic, forest, and rangeland systems have undergone dramatic changes. Forested landscapes are more susceptible to fire, insect, and disease than under historic conditions. Rangelands are highly susceptible to noxious weed invasion. The disturbance regimes that operate on forest and rangeland have changed substantially, with lethal fires dominating many areas where non-lethal fires were the norm historically. Terrestrial habitats that have experienced the greatest decline include the native grassland, native shrubland, and old forest structures. There are areas within the Assessment area that have higher diversity than others. Aquatic systems are now more fragmented and isolated than historically and the introduction of non-native fish species has complicated current status of native fishes. Core habitat and population centers do remain as building blocks for restoration. Social and economic conditions within the Assessment area vary considerably, depending to a great extent on population, diversity of employment opportunities, and changing demographics. Those counties with the higher population densities and greater diversity of employment opportunities are generally more resilient to economic downturns. This Assessment provides a rich information base, including over 170 mapped themes with associated models and databases, from which future decisions can benefit.

	Citation Citation Citation Abstract Copy Title: Undepleted natural flow of the upper Klamath River : natural inflow to, natural losses from, and natural outfall of Upper Klamath Lake to the Link River and of Lower Klamath Lake to the Klamath River at Keno Author: United States. Bureau of Reclamation. Denver Office. Technical Service Center Year: 2005, 2004 A monthly natural flow history was determined for the 1949 to 2000 period at the Keno gage of the Upper Klamath River basin in south-central Oregon. Included within the evaluation is an assessment of natural flows for the same period at the outfall of Upper Klamath Lake, which forms the head of the Link River at Klamath Falls, Oregon. Flow past the Link River gage is tributary to the Klamath River above Lower Klamath Lake. These natural flows were determined using standard and accepted methods. Records used in developing this analysis were derived from stream-gaging records and from climatic records for stations within and adjacent to the study area. Information was also obtained from published maps and reports, and file documents of the Klamath Area Office. Currently, received comments are being addressed and evaluation of elements related to these comments is in progress. The objective of this report is to provide a representative estimate of the monthly natural flow of the Upper Klamath River. Such an estimate is of the natural flow that would typically have occurred without the water-resources developments in the Upper Klamath Basin. A water-budget assessment was used in the determination of the natural flows. The assessment includes results from an evaluation of present-day irrigation depletions, and losses from reclaimed marshland, that have changed the natural inflow to, and resulting natural outfall from, Upper Klamath Lake. Also evaluated were losses to the natural inflow that would have been incurred due to pre-development marshland and evaporation associated with Upper Klamath Lake. The natural outfall from the lake comprised the natural flow of the Link River at Klamath Falls and also the consequent natural inflow to Lower Klamath Lake. Therefore, a similar evaluation was also completed for Lower Klamath Lake to estimate the natural flow of the Klamath River at Keno. The water-budget assessment was designed to simulate each lake as a natural water body within a stream-connected two-lake system. Much of the assessment was completed using Excel.
