Year: 1948, 2004 SUMMARY To provide a basis for negotiations of a repayment contract with an irrigation district representing the water users of the Tule Lake Division of the Klamath Project, this report has been prepared. It covers past, present, and anticipated future agricultural and economic conditions and substantiates the proposed district's capacity to repay construction costs for irrigation water as well as to meet operation and maintenance charges It has been prepared according to procedures and policies established pursuant to the Federal Reclamation laws (Act of June 17, 1902, 32 Stat. 388, and acts amendatory thereof and supplementary thereto.) In general, a representative farm budget method of analysis was employed to determine the payment capacity* Gross income of the land was based upon average per acre yields in the area and 1939-44 prices received. Prices of certain crops were adjusted further in accordance with long term outlook for these crops. From the gross income, all farm operating and retention expenses, including cultural and harvesting costs, taxes, insurance, depreciation and replacement, interest on investment, and a reasonable allowance for family living predicated upon the same base period (1939-44) have been subtracted to arrive at payment capacity. Individual consideration has been given to the block of land entered prior to 1948 (the major portion of the area), the lands of the Coppock Bay Area which are principally Class 2, and the undeveloped lands of the area just south of Malin, Oregon, Area C, Plate 1. The annual payment capacity of the irrigable lands entered prior to 1914-8, is determined to be approximately $50 per acre. The Class 2 lands of the Coppock Bay Area are shown to have a payment capacity of $21 per acre, as a result of slightly higher operating costs and probable lower yield or quality of certain crops. For the undeveloped area just south of Malin, Area C of Plate 1, the payment capacity is determined at $18 per acre after development to the extent expected under settlement and development plans currently being formulated The weighted average payment capacity for these areas is calculated to be $26.25 per acre. There is no need for a development period for the lands of the Tule Lake Division, except for the latter area as indicated above. Furthermore, after liberal allowance for farming costs and a reasonable family living, the resulting payment capacities appear to be well in excess of any annual installments likely to be considered necessary for repayment of the District's construction obligation and operation and maintenance charges.

Year: 2002, 2005 Determining Surface Water Availability in Oregon By Richard M. Cooper, PE Abstract The Oregon Water Resources Department (Department or OWRD) limits appropriation from Oregon streams to assure new applicants use of surface water a reasonable amount of time and to minimize regulatory conflict. The standards for new appropriation of water are: (1) consumptive use from allocations for out-of-stream uses can total no more than the 80-percent ex-ceedance natural stream flow, and (2) allocations for in-stream flows can be no more than the 50-percent exceedance natural stream flow. OWRD has created and maintains a database of the amount of surface water available for appropriation for most waters in the state. This database is used to evaluate applications for new uses of water. Water availability (WA) is obtained from natural stream flow (QNSF) by subtracting existing storage (ST), out-of-stream consumptive uses (CU) and in-stream demands (IS). WA = QN -ST-CU-IS Ideally, water availability would be calculated for every watershed above a point of diversion or in-stream demand. Practically, the number of watersheds must be limited. The watersheds selected for analysis are called Water Availability Basins (WABs). Stream flow can be highly variable, and it is useful to characterize it in some way, usually by a statistic, e.g., a monthly or annual mean. For water availability, it is important to know how often water is available. The appropriate statistic in this case is exceedance stream flow. This statistic tells us how often to expect a given rate of stream flow to occur. Exceedance stream flows are determined directly from gage records, or for ungaged streams, by estimation through modeling. When determined from gage records, the exceedance flows must be corrected to a common base period, and then, to natural stream flow. When determined through modeling, the exceedance flows are estimated from statistical models that relate watershed characteristics to natural stream flow. The models are derived by multiple linear regression. Storage is water retained in a reservoir. It is debited from water availability when the water is stored. It diminishes availability both upstream and downstream of the point of diversion. Consumptive use is divided into three major categories: irrigation, municipal, and all others e.g., domestic, livestock. These uses are less than 100 percent consumptive. It is assumed the non-consumed part of a diversion is returned to the stream from which it was diverted. Consumptive use from irrigation is from estimates made by the US Geological Survey (Portland). Consumption from other uses is based on the associated water rights. In these cases, consumptive use is obtained by multiplying the maximum diversion rate allowed for the water right by a consumptive use coefficient. Consumptive use diminishes availability both upstream and downstream of the point of diversion. There are two types of in-stream demands: in-stream water rights and scenic waterway flows. In-stream demands diminish availability upstream only. Because they are non-consumptive, they do not diminish stream flow downstream as do consumptive uses. Water availability has been calculated for over 2500 WABs. In general, the calculation of water availability at one WAB cannot be considered in isolation from other WABs in the same stream system. For water to be available at any given upstream point, it must be available at all points of calculation downstream.
