Water marketing, or mechanisms to acquire and redistribute water such as temporary water transfers, can represent a valuable response to drought for irrigation districts. The Department of Ecology, the US Bureau of Reclamation, and a workgroup composed of members from various entities collaborated to develop the Yakima River Basin Integrated Water Resource Management Plan (Integrated Plan) to better manage water resources and address ecosystem issues in the Yakima River Basin. The Integrated Plan addresses water marketing but it does not provide specifics on how barriers to inter‐district water transfers will be eliminated. This study asks irrigation district managers in the Yakima River basin about the factors they consider when deciding whether to engage in a temporary inter‐district water transfer or not. Results show that institutional barriers are the most common barrier to inter‐district water transfers. This topic requires further research on fallowing and irrigation district behavior in relation to the other water supply efforts outlined in the Integrated Plan. Finally, the water market in the Yakima basin can benefit from education and outreach to senior water rights holders, shortening the time frame to process expedited transfers, and documentation from irrigation districts reporting denial reasons for temporary inter‐district water transfers.

Background: In paediatric clinical practice treatment is often adjusted in relation to body size, for example the calculation of pharmacological and dialysis dosages. In addition to use of body weight, for some purposes total body water (TBW) and surface area are estimated from anthropometry using equations developed several decades previously. Whether such equations remain valid in contemporary populations is not known. Methods: Total body water was measured using deuterium dilution in 672 subjects (265 infants aged < 1 year; 407 children and adolescents aged 1-19 years) during the period 1990-2003. TBW was predicted (a) using published equations, and (b) directly from data on age, sex, weight, and height. Results: Previously published equations, based on data obtained before 1970, significantly overestimated TBW, with average biases ranging from 4% to 11%. For all equations, the overestimation of TBW was greatest in infancy. New equations were generated. The best equation, incorporating log weight, log height, age, and sex, had a standard error of the estimate of 7.8%. Conclusions: Secular trends in the nutritional status of infants and children are altering the relation between age or weight and TBW. Equations developed in previous decades significantly overestimate TBW in all age groups, especially infancy; however, the relation between TBW and weight may continue to change. This scenario is predicted to apply more generally to many aspects of paediatric clinical practice in which dosages are calculated on the basis of anthropometric data collected in previous decades.
