Interpretation of short term water level fluctuations in the Moscow Basin Latah County, Idaho. Pamphlet 137 Item Info

Moscow basin is underlain by a sequence of basalts and intercalated sediments along the eastern margin of the Columbia Plateau. The sequence includes at least 5 aquifers that are separated by rocks with such low permeability that hydraulic connection among aquifers is extremely poor. Not E>.ll aquifers are everywhere present throughout the basin. Potentiometric surfaces of deeper aquifers are successively lower. Each aquifer has a distinctive pattern ci. seasonal water-level fluctuations. Waterlevel rises correlate with rainfall in the basin and with snow melt and relatively heavy surface runoff from adjacent mcuntainous areas. All aquifers, except the lowermost, show seasonal recharge indicating that each is part of an active hydrologic system. Informa,tion on the lowermost is insufficient to determine if it is now being recharged significantly. Water levels in some wells responded to changes in barometric pressure, pumping in other wells, earthquakes, and wind, in addition to seasonal recharge. The largest fluctuation, caused by the Good Friday, 1964, earthquake in Alaska, was more than five feet. No permanent change in water level could be attributed to this or any other earthquake. Seasonal fluctuation of one-half foot in one well was identified by two methods, although the record was obscured by barometric fluctuations of more than one and one-half feet.
