Annual summary of ground-water conditions in Arizona, spring 1986 to spring 1987

Water availability and use pilot: Methods development for a regional assessment of groundwater availability, southwest alluvial basins, Arizona

“…Although estimates were not developed for all 45 groundwater basins in the study area, the 15 basins investigated account for more than 85 percent of the total historical groundwater withdrawals for the State through 1987 (Konieczki and Wilson, 1992) and therefore represent most of the change in aquifer storage within the study area. Estimating the change in aquifer storage since before development for the most developed SWAB basins in Arizona involved basic hydrologic analyses of historical and recent groundwater-level surfaces.…”

“…Owing to time and budget constraints, groundwater indicators for only the 19 basins with the greatest historical groundwater withdrawals were developed and are presented here. These basins account for more than 96 percent of the estimated groundwater withdrawals in the State through 1987 (Konieczki and Wilson, 1992) and are referred to as the "most developed basins" in this section. For each indicator presented, with the exception of Recent Depth to Groundwater, hydrographs of all wells meeting the selection criteria were visually inspected to ensure a qualitative agreement between the groundwater-level data and the indicator.…”

“…In general, ground-water data are most plentiful in the AMAs, but some data exist in nearly all areas. Basins are being addressed in this project in the order of decreasing historical ground-water development according to pumpage records (Konieczki and Wilson, 1992). Analyses of several of the groundwater basins delineated by ADWR have been completed ( fig.…”
