A three-dimensional groundwater flow model using MODFLOW-NWT was developed to evaluate historical and potential stream capture in the lower Humboldt River Basin, Nevada. The Humboldt River Basin is the only river basin that is contained entirely within the state of Nevada. The effect of groundwater pumping on the Humboldt River is not well understood. Tools are needed to determine stream capture and manage groundwater pumping in the Humboldt River Basin. Previous work has demonstrated that the river’s surface-water resource is sensitive to groundwater withdrawals, which have steadily increased since the 1950s for agriculture, municipal, and mining uses. A numerical groundwater flow model was developed for the purpose...

This data release consists of a Microsoft® Access database and Microsoft® Excel workbook that contain water-level data and other hydrologic information for wells in and near areas of underground nuclear testing at the Nevada Test Site (currently called the Nevada National Security Site). The database provides information for each well (well construction, borehole lithology, units contributing water to the well, and general site remarks) and associated water-level measurements (measurement source, status, method, accuracy, and specific water-level remarks). Additionally, the database provides hydrograph descriptions that document the water-level history and describe and interpret the water-level hydrograph for each...
