	Citation Citation Citation Abstract Copy Title: Geology and ground-water resources of the Swan Lake-Yonna Valleys area, Klamath County, Oregon Author: Meyers, Joseph D. Year: 1952, 2007, 2005 Abstract The Swan Lake-Yonna Valleys area consists of two intermountain valleys with their subordinate side valleys adjoining slopes, and mountainous boundary ridges, In all the area covered is about 256 square miles but the essential agricultural sections are restricted to the floors of Swan Lake and Yonna valleys with their respective subsidiary extensions of Pine Flats and Alkali Lake flats, a valley-floor area totaling about 90 square miles The floors of Swan Lake Valley and Yonna Valley lie at an altitude of about U52OO feet but the mountainous boundary ridges rise generally to 6000 feeto Yonna Valley is largely drained to Lost River by Buck Creek but also in part to Alkali Lakeo Swan Lake Valley and Pine Flats have only internal drainage. The Swan Lake Valley floor is the top of a deep alluvial fill, while Yonna Valley floor is mainly an erosional surface sloping to lines of through drainage Precipitation is about lit inches annually on the valley floors 9 but must be much more, possibly 18 to 24 inches, on the higher parts of the drainage basins. The growing season is short and killing frosts do occur in late spring and early fall. The rock units forming the bedrock structure of the area are consolidated or semiconsolidated rocks of Tertiary age and are largely of volcanic-flow and volcanic-sedimentary originc They consist of three main elements, a lower lava-rock unit, a sedimentary and volcanic-sedimentary unit, and an upper lava-rock unito The unconsolidated deposits are the older alluvium of Quaternary (and in part of late-Tertiary) age and the younger alluvium of Quaternary age0 The bedrock is faulted and deformed particularly so along a northwest-southeast set of fault lines that have given a remarkable linearity to the topography. Unpublished records subject to revision Ground water occurs below a regional water table that slopes south-ward to the level of the Lost Rivero The upper lava rocks and the lower lava rocks contain the principal permeable zones that occur beneath the areao Breccia and other porous zones in those rocks in places yield water to wells at a rate as large as 35OOO gallons per minute with but 1 or 2 feet of drawdowno The economical construction of irrigation wells requires the determination of the best possible location at which those rocks may be tapped at shallow depth below the level of the water tableo The ground water in general relatively low in dissolved mineral matter and is but slightly to moderately hard and would be considered chemically satisfactory for most uaeso Irrigation is the principal use of the ground water in the area north of the Horsefly Irrigation Districto There 3? wells supplied about 6,000 acre-feet of water to about 3800 acres of land in 1950. Water-level records obtained since 19U8 and approximations of the probable annual recharge from precipitation indicate that the present withdrawals are considerably less than the annual increment of the ground-water recharge, Rough estimates indicate that an increase in withdrawals of as much as 100 percent or more can take place before ground-water levels, by a persistent lowering, will begin to indicate that the annual replenishment is being exceeded.

	Citation Citation Citation Abstract Copy Title: Water temperature monitoring of the Klamath River mainstem: final report Author: Karuk Tribe of California Year: 1999, 2005 WATER TEMPERATURE MONITORING KLAMATH RIVER MAINSTEM ABSTRACT This report summarizes the water temperature data collected by the Karuk Tribe of California (Karuk Tribe) from July 1993 to September 1997 at thirteen locations along the Klamath River from Upper Klamath Lake to the mouth of the Klamath River at the Pacific Ocean. This report describes the water temperature monitoring system designed by the Karuk Tribe, the data checks that were performed, and a summary of the water temperature data results. The Karuk Tribe began this study in part in response to the Klamath River Basin Fisheries Task Force stated objective to monitor water temperature conditions above, within, and below existing water projects along the Klamath River. With help from the California Department of Fish and Game, PacifiCorp, and the Klamath National Forest, this project was expanded from six to thirteen original monitoring sites in 1993. Water temperature data were collected by Ryan TempMentor? instruments typically on an hourly time interval. The data was checked for accuracy by consultants and reduced for this report to mean daily water temperature values each year on a monthly basis in US Geological Survey tabular format. Mean value data were entered into a Microsoft Access relational database for use on an IBM compatible computer. Although the period of record for the Klamath River water temperature data stretches over 5 years, several gaps in data inhibit detailed analysis. The analysis presented, illustrates when the minimum and maximum preferred temperature ranges for salmonids are exceeded. In addition, preliminary temperature trend shows that in August water temperature values below Iron Gate Dam were lower than other monitoring stations further downstream. Conversely, water temperature values in October are warmer below Iron Gate than in the unregulated reaches of the Klamath River downstream. Given this information, it appears that releases from Iron Gate Dam do influence the natural water temperature balance in the Klamath River. To more accurately determine the extent of reservoir releases on the natural thermal environment, additional water temperature measurements need to be collected.
