Background The North Atlantic Coastal Plain (NACP) covers a land area of approximately 34,000 mi 2 along the eastern seaboard of the United States from Long Island, N.Y., southward to the northern portion of North Carolina. This area is underlain by a thick wedge of sedimentary deposits that form a complex groundwater system in which the sands and gravels function as confined aquifers, and the silts and clays function as confining units. These confined aquifers of the NACP constitute a major source of water for public and domestic supply for the nearly 27 million people living in the region, as well as being important source of water for industrial and agricultural purposes. Increases in population and changes...

Delivering adequate water supplies to support expanding human enterprise while maintaining the necessary flow regimes to support desired riparian ecosystems and formally protected wildlife species that depend upon them is increasingly difficult in the arid western United States. Many riparian systems have undergone dramatic alteration over the last 50 - 100 years, exacerbating the conflicts between resource use and biodiversity protection. One of the most visible changes that is in part due to altered flow regimes is the establishment of invasive plant species in riparian ecosystems. The highest priority invasive riparian plant is the Eurasian tree/shrub, tamarisk (or saltcedar, Tamarix spp.) the third most abundant...

Consistent with sound business practice and the Agency’s stewardship responsibilities, Reclamation is continuously striving to identify and apply advanced approaches allowing the operation of Reclamation hydropower plants in a more efficient manner—generating more electricity per acre-foot of water released. One of the challenges of efficient hydropower generation is the matter of setting short-term generation schedules from multiple sources. On at least an hourly basis, Reclamation’s power plant operators must determine the best combination of generator units to bring online, and at what levels, given the existing demand for electricity and other operating costs and constraints. This is known as the economic dispatch...
