Verde River Stories
Why is this study important? It represents a critical first step in characterizing the streamflow requirements of habitat and wildlife along the Verde River. Haney, J.A., Turner, D.S., Springer, A.E., Stromberg, J.C., Stevens, L.E., Pearthree, P.A., and Supplee, V., 2008, Ecological Implications of Verde River flows: A report by the Arizona Water Institute, The Nature […]
Why is this study important? This modern geologic map synthesizes the work of dozens of geologists over decades into a unified, comprehensive map of the upper and middle Verde River watersheds. DeWitt, Ed, Langenheim, Victoria, Force, Eric, Vance, R.K., Lindberg, P.A., and Driscoll, R.L., 2008, Geologic map of the Prescott National Forest and the headwaters […]
Why is this study important? It represents the most recent published groundwater-flow model analysis specifically for the Little Chino Sub-basin. Timmons, Daniel, and Springer, Abe, 2006, Prescott AMA model update report: Arizona Department of Water Resources, 77 p. In 1995, the Arizona Department of Water Resources developed a regional groundwater-flow model to quantify the impacts […]
Why is this study important? This report combines data collected from boring deep narrow holes into the ground with new aeromagnetic and gravity measurements. This combination of data provides the most comprehensive analysis to date of the thickness, shape, and boundaries of basin-fill aquifers of the Big Chino, Little Chino, and Verde Valley sub-basins. Langenheim, […]
Why is this study important? The report applies multiple lines of evidence to examine contributions to the baseflow of the upper Verde River. It concludes that the Little Chino aquifer provides approximately 14 percent and the Big Chino aquifer system provides between 80 and 86 percent of the Verde River baseflow measured at the Paulden […]
Why is this study important? This report represents several years of fieldwork and analysis by the U.S. Geological Survey and the Arizona Department of Water Resources. It provides well-documented, fundamental geologic and hydrologic information essential to the more recent development of the northern Arizona regional groundwater-flow model. Blasch, K.W., Hoffmann, J.P., Graser, L.F., Bryson, J.R., […]
Why is this study important? This is a brief summary and explanation of the more comprehensive report by Leake and Pool (2010). It is written in a style with the general public in mind, rather than an audience of scientists. Leake, S.A., and Haney, Jeanmarie, 2010, Possible effects of groundwater pumping on surface water in […]
Why is this study important? This is the first published application of the Northern Arizona regional groundwater-flow model. It predicts the effect of either pumping from wells or of artificial recharge on streamflow in the Verde Valley Basin. Leake, S.A., and Pool, D.R., 2010, Simulated effects of groundwater pumping and artificial recharge on surface-water resources […]
Why is this study important? This study documents a powerful new tool—the Northern Arizona regional groundwater-flow model—that enables elected officials and water-resource managers to evaluate the future consequences of local or regional water-management policies for groundwater levels and streamflow in the Verde River Basin. Pool, D.R., Blasch, K.W., Callegary, J.B., Leake, S.A., and Graser, L.F., […]
Why is this study important? It is the product of the authorization by the United States Congress for the United States Geological Survey (USGS) to assist in a collaborative and science-based water-resource planning and management partnership for the Verde River Basin. It describes the investigations needed in support of that authorization that will fulfill water-resource […]
