Hydrologic interpretation of temporal variation in springs and wells in the Thousand Springs area, Idaho. Technical completion report 05-001 Item Info

An understanding of the relationship of spring discharge to aquifer water level is fundamental to modeling and managing the Eastern Snake River Plain Aquifer. Previous work has suggested that these relationships appear nearly linear but frequently are inconsistent with field observations of spring elevation. The purpose of this report is to document recently collected spring discharge and nearby aquifer water-level data and further evaluate the relationship between these measurements. Spring discharge is compared to aquifer water levels for 14 spring-well pairs. In most cases, the relationship between the spring discharge and well water level is approximately linear within the limited data range. In a few cases, either spring discharge or well water level exhibits atypical behavior and the linearity is diminished. This may be due to local recharge and discharge activities near either the spring or well. Extrapolation of the relationships consistently indicates that spring elevation should be higher than that observed in the field (the x-axis intercept). This implies that a non-linear relationship may exist below the data range observed, or that systematic errors were encountered in measurement of spring discharge or aquifer water level. Non-linearity at lower spring discharges could be due to unconfined aquifer conditions or other unknown phenomena.
