New Hampshire

New Hampshire is in the temperate broadleaf and mixed forests biome and is the state with the highest percentage of timberland area in the country. Much of the state, in particular the White Mountains, is covered by the conifers and northern hardwoods of the New England-Acadian forests. New Hampshire also has the shortest ocean coastline of any state in the United States, approximately18 miles.

Arsenic variability in water-supply wells

The USGS, in cooperation with the Town of Seabrook, New Hampshire and a private well owner, is assessing the variability of arsenic over multiple time scales. A network of three wells is being used to monitor changes in arsenic, arsenic species, a host of other chemical constituents, and the distribution of ages of groundwater entering the wells. The wells—one domestic bedrock aquifer well,...

Climate Change, Hydrologic Responses and Impacts on Carbon Cycling as Inferred by Changes in Fluvial Dissolved Organic Carbon Fluxes

This project investigates the links between terrestrial and marine carbon cycling and fluvial transport of freshwater and dissolved organic carbon (DOC) to the near-coastal ocean. The project analyzes DOC export that integrates complex interacting processes in natural and human-impacted terrestrial and aquatic environments. Changes in DOC export may indicate changes in terrestrial ecosystem...

Geospatial Dataset of Wells and Attributes in the New England Groundwater Level Network, 2017

The drought of 2016 affected hydrologic conditions throughout New England. Responses of USGS groundwater observation wells to this event, however, were not uniform and were sometimes markedly different from site to site. Although USGS scientists were able to provide explanations for most of these situations, the event highlighted the need for additional well information to develop quantitative...

Development of Streamflow Record Extension Equations in New Hampshire

Currently, there are 16 designated rivers in New Hampshire in need of daily mean streamflow estimates for managing instream flows. Many of New Hampshire’s Designated Rivers have current and/or historical streamflow data that may be used to extend an existing streamgages streamflow record in time through record extension techniques. Evaluating the feasibility of record extension techniques to...

Nutrient Loads from the Upper Connecticut River Watershed

River-borne nutrients, especially nitrogen, contribute to water-quality degradation in Long Island Sound. The Connecticut River is the largest tributary to the Sound, and quantification of nutrient loads from the three upper States in the watershed, as well as the State of Connecticut, is essential for prioritizing efforts to improve the Sound’s water quality.

Orthoimagery Data

Orthoimagery data typically are high resolution aerial images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a planimetric map. The National Map offers public domain, 1-meter orthoimagery for the conterminous United States with many urban areas and other locations at 2-foot or finer resolution.

The National Map Small-Scale Collection

The National Map offers a collection of small-scale datasets, most of which are at 1:1,000,000. The National Map publishes two data collections at one million-scale: one for Global Map users and one for National Map users. In terms of vector geometry, the lines, points, and areas in these data collections are identical. The difference is in the attributes assigned to these features.

High-resolution geophysical and sample data collected in Moultonborough Bay, Lake Winnipesaukee, New Hampshire in 2005, U.S. Geological Survey Field Activity 2005-004-FA

 This study utilized geophysical systems and conventional water-quality measurements to identify lake-floor environments that may provide suitable habitat for the establishment and growth of variable leaf water-milfoil. The results of the study are intended to assist resource managers in federal and state agencies.

Estimated withdrawals and use of freshwater in New Hampshire, 1990

Estimated freshwater withdrawals during 1990 in New Hampshire totaled about 422 million gallons per day from ground-water and surface-water sources. The largest withdrawals were for thermoelectric-power generation (60 percent), public supply (23 percent), and industrial use (9 percent). Most withdrawals, 358 million gallons per day, were made from...

National water summary 1987: Hydrologic events and water supply and use

Water use in the United States, as measured by freshwater withdrawals in 1985, averaged 338,000 Mgal/d (million gallons per day), which is enough water to cover the 48 conterminous States to a depth of about 2.4 inches. Only 92,300 Mgal/d, or 27.3 percent of the water withdrawn, was consumptive use and thus lost to immediate further use; the...
