Abstract
The Moscow basin encompasses an area of 65 square miles (170 square kilometres) in Latah County and borders the Idaho Washington State line (fig. 1). The basin is along the eastern edge of the "Palouse Country" where the rolling Palouse hills merge with the low mountains of northern Idaho. It is drained by the South Fork Palouse River, Paradise Creek, and Missouri Flat Creek, and their headwater tributaries.
All water supplies for the basin are derived from wells and springs. Virtually all large-capacity wells are owned by the City of Moscow and the University of Idaho. These wells are open to the basalt of the Columbia River Group and the interbedded sands in the Latah Formation (Stevens, 1960, p. 335; Jones and Ross, 1972, p. 12-13, fig. 4). Many domestic and a few commercial wells are also open to these same formations. Most of the City and University wells tap thick sections of these water-bearing formations. However, only about 25 percent of the total basin area is underlain by basalt. The approximate subsurface extent of the area underlain by basalt, as determined by well logs and geophysical data, is shown in figure 2.
The purpose of this report is to present basic geologic and hydrologic data that are available in the basin. Included are a table of well records, well logs, a table of annual ground-water withdrawals, water levels in observation wells, a contour map showing the approximate elevation of the water-level in the upper series of basalt flows and interbedded sediments in the southern part of the area (fig. 2), and a bibliography of the more important reports pertaining to ground water in the area. More than 90 percent of the wells tapping basalt were visited, but only a representative number of wells tapping other rocks were visited. Data that may have become available after December 1972 are not given except for water-level measurements made in March 1973.
