[1] We created six new tree-ring chronologies in northern Utah, which were used with preexisting chronologies from Utah and western Wyoming to reconstruct mean annual flow for the Logan River, the largest tributary of the regionally important Bear River. Two reconstruction models were developed, a “Local” model that incorporated two Rocky Mountain juniper chronologies located within the basin, and a “Regional” model that also included limber pine and pinyon pine chronologies from a larger area. The Local model explained 48.2% of the variability in the instrumental record and the juniper chronologies better captured streamflow variability than Douglas-fir collected within the …

An accurate method for determination of in situ soil water flux density continues to be the most sought after and yet elusive hydrologic measurement. The penta-needle heat pulse probe (PHPP) employs a central heater needle surrounded by an orthogonal arrangement of four thermistor needles for two-component water flux density estimation. An analytical solution and inverse fitting method are presented for simultaneous estimation of thermal properties and soil water flux density using PHPP measurements. The approach yields estimates of both components of the flux in a plane normal to the axis of the PHPP needles. The method was evaluated using data …

Weber Basin Water Conservancy District (District) secured Bureau of Reclamation funding in spring 2011 to install individual secondary water meters at residential connections in order to implement water efficiency and accountability measures included in the District’s Water Conservation Plan (Weber Basin Water Conservancy District, 2010). Initially, the District will not use the meters for billing water use but, instead, will use them to help the District determine if end users are exceeding their contracted allotment of water and to promote water use accountability.The purpose of the study titled “Water User Dimensions of Meter Implementation on Secondary Pressurized Irrigation Systems” conducted …
