Hydrologic Studies in the East Mountain Area of Bernalillo County, NM

Recent expansion of suburban development and population growth in the Sandia Mountains of eastern Bernalillo County, NM (East Mountain Area, EMA), has led to increased residential and commercial construction and increased demands on available water resources. Information about the spatial and temporal variability of water resources is needed for continued population and economic growth....

Changes in Groundwater Levels in the Albuquerque Metropolitan Area

The U.S. Geological Survey, in cooperation with the Albuquerque Bernalillo County Water Utility Authority (ABCWUA) has been investigating the effects of groundwater withdrawal on groundwater levels throughout the Albuquerque metropolitan area in the Middle Rio Grande Valley of central New Mexico (fig. 1). Historically, the water supply requirements of the Albuquerque metropolitan area were met...

Aquifer Compaction, Recovery, and Land-surface Elevation Change in the Albuquerque Basin

In many groundwater basins in the arid to semiarid western United States, permanent regional-scale land-surface elevation change has resulted from substantial drawdown of groundwater levels. By the end of 2008, groundwater drawdown from municipal pumping in the Albuquerque area had reached as much as 120 feet below predevelopment (~1950s) water levels. In 2014 the USGS, in cooperation with the...

Updating Low-Flow Statistics at USGS Streamgages and Regionalization of Selected Low-Flow Characteristics for Alabama Streams

As part of their mission to protect public health and aquatic ecosystems, Alabama state agencies need accurate and representative streamflow statistics to establish realistic and applicable criteria for both water quality and water quantity (fig. 1). Historically, low-flow statistics, such as the annual minimum 7-day average flow that likely will occur, on average, once every 10 years (7Q10),...

Upper Kittitas County

The Issue: Baseflows in the tributary streams in the western portion of Kittitas County are important in the late summer and fall when demands on these streams peak. An ongoing USGS Yakima River basin study indicates that groundwater and surface water are interconnected, however the hydrogeologic framework and the potential impacts of groundwater withdrawals on tributary streamflow in the...

Recharge and frozen ground in the PNW

The Issue: Seasonally frozen ground occurs over approximately one-third of the contiguous United States, and the extent and duration of frozen ground have been decreasing as a result of global warming. In semi-arid regions such as the Columbia Plateau and Snake River Plain in the Pacific Northwest, nearly all natural recharge occurs between October and March when intermittent...

Assessing Groundwater/Surface Water Interaction and Stream Discharge Uncertainty in the Snake River

The State of Idaho needs to determine stream discharge, adjusted to remove fluctuations resulting from the operation of hydropower facilities, in the Snake River below Swan Falls Dam near Murphy, Idaho. The State will use this information to distribute water to owners of water rights in the middle Snake River, particularly at thresholds of 3,900 and 5,600 ft3/s.
