Harvey, F. E., Swinehart, J. B., Kurtz, T. M. 2001. Hydrogeology and Hydrochemistry of the Jumbo and Pullman Valley Fens, Cherry County, Nebraska (OFR-58). Appoximately 135 pp., size 8.5" x 11". Description: The purpose of this study was to characterize the physical and chemical hydrogeology of the Jumbo and Pullman Valley fens. Physical characterization was to provide information on the shallow geology of the fen, the local water table, seasonal groundwater levels, local groundwater flow dynamics, hydraulic gradients and hydraulic conductivity of the peat and groundwater flux into the fen. Chemical characterization of the groundwater was to determine the major ion chemistry, nutrient chemistry, origin of the groundwater and age of recharge of the local groundwater.
