Maine is the northernmost and least densely populated state in the contiguous United States east of the Great Lakes. It is known for its jagged rocky coastline; low rolling mountains; heavily forested interior and picturesque waterways. Geologists describe this type of landscape as a "drowned coast", where a rising sea level has invaded former land features, creating bays out of valleys.
The USGS Soil-Water-Balance model (SWB) is being used to estimate potential recharge across the State of Maine. The average and range (minimum and maximum) of annual recharge were estimated for the 25-year period from 1990 to 2015.
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, staff who participated in drought advisory panels realized the need for a quantitative...
FEMA has requested USGS expertise in hydraulics, hydrology, and mapping to general Flood Insurance Maps for New England.
Development of Regional Regression Equations to Estimate the Magnitude of Peak Flows for Selected Annual-Exceedance Probabilities in Maine
Knowledge of the magnitude and frequency of floods is needed for the effective and safe design of bridges, culverts, and other structures. This information is also important for flood-plain planning and management. The flood-frequency characteristics for streamgages and regression equations for estimating flood magnitudes at ungaged sites were last developed in 1999 (Hodgkins, 1999).
This project will provide a deterministic watershed model of the Meduxnekeag River watershed with a capacity to model water-temperatures capable of simulating future hydrologic and temperature changes based on projected climate estimates.
The Bird Banding Laboratory (BBL) is an integrated scientific program established in 1920 supporting the collection, archiving, management and dissemination of information from banded and marked birds in North America. This information is used to monitor the status and trends of resident and migratory bird populations. Because birds are good indicators of the health of the environment, the...
Development of a Multimetric Index for Integrated Assessment of Salt Marsh Condition in the Northeast Coastal and Barrier Network
Salt marsh ecosystems along all US coastlines have been altered, degraded, and destroyed by human activities, including ditching and drainage of the marsh platform, tidal restrictions, discharge of pollutants, and introduction of invasive species. The National Park Service conducts long-term monitoring of salt marsh vegetation and nekton (fish and free-swimming crustaceans) to provide...
Recovery of Eelgrass (Zostera marina L.) in Casco Bay, Maine, Following Destruction by European Green Crabs
Eelgrass provides essential functions to the ecology and economy of Maine’s coastal zone. When over half the eelgrass in Casco Bay, Maine, disappeared between 2012 and 2013, USGS experimental evidence identified disturbance from invasive European green crabs as the leading cause. Natural revegetation is occurring, but there is interest in learning whether restoration may hasten recover.
Estuaries worldwide are threatened by nutrient over-enrichment from watershed development. USGS led development of a regional protocol to monitor estuarine nutrient status in northeastern coastal National Parks. Synthesis and reporting of monitoring results at local and regional scales allows park managers to identify changing nutrient loads and susceptibility to eutrophication.
Seagrasses are among the most productive ecosystems on the planet. Worldwide losses of this important habitat have been caused by water quality degradation association with watershed development. Improved approaches to detect threats of nutrient enrichment are paramount to seagrass conservation.
Use of Structured Decision Making to Optimize Salt Marsh Management Decisions at Northeastern National Wildlife Refuges
A regional assessment of salt marsh integrity (SMI) has been completed on 15 National Wildlife Refuges/Refuge Complexes in the northeastern US. Developed within a structured decision making (SDM) framework, the SMI assessment provides essential baseline data on salt marsh condition relative to regional management objectives. These data now provide the basis for applying the SDM framework to...

USGS data portray selected structures data, including the location and characteristics of manmade facilities. Characteristics consist of a structure's physical form (footprint), function, name, location, and detailed information about the structure. The types of structures collected are largely determined by the needs of the disaster planning and response and homeland security organizations.
Boundaries data or governmental units represent major civil areas including states, counties, Federal, and Native American lands, and incorporated places such as cities and towns.
The National Hydrography Dataset (NHD) and Watershed Boundary Dataset (WBD) are used to portray surface water on The National Map.

Predators shape distribution and promote diversification of morphological defenses in Leucorrhinia , Odonata
Predators strongly influence species assemblages and shape morphological defenses of prey. Interestingly, adaptations that constitute effective defenses against one type of predator may render the prey susceptible to other types of predators. Hence, prey may evolve different strategies to escape predation, which may facilitate adaptive radiation...Petrin, Zlatko; Schilling, Emily Gaenzle; Loftin, Cyndy; Johansson, Frank
Effects of introduced fish on macroinvertebrate communities in historically fishless headwater and kettle lakes
Widespread fish introductions have led to a worldwide decline in the number of fishless lakes and their associated communities. Studies assessing effects of fish stocking on native communities in historically fishless lakes have been limited to high-elevation headwater lakes stocked with non-native trout. Little is known about the effect of fish...Schilling, Emily Gaenzle; Loftin, Cynthia S.; Huryn, Alexander D.
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...Carr, Jerry E.; Chase, Edith B.; Paulson, Richard W.; Moody, David W.

USGS field crews are deploying storm-tide and wave sensors today from Maine to Delaware to track and study a Nor’easter forecasted to begin tomorrow.
Significant flooding along the coast of Massachusetts occurred Thursday, January 4, 2018, caused by a powerful blizzard. Peak storm surge of approximately 3.00 feet occurred at the astro high tide; and, according to the National Weather Service, is the highest since records began at the Boston tide station in 1921.
A carbonatite here, a glacial moraine there, a zig-zagging fault or two, even a behemoth of a batholith. The geology of the 50 States is an enormous patchwork of varied forms, beautiful in their variance but challenging to present as a single map.
If coastal salt marshes are like savings accounts, with sediment as the principal, all eight Atlantic and Pacific coast salt marshes studied are "in the red," researchers found.
A high-tech buoy that monitors water quality in real time was just installed in one of New England’s most popular lakes, where in the future it will help with determining when swimmers should and shouldn’t be in the water.
New USGS models help predict storm effects on beaches
As the 2016 hurricane season opens, weather forecasters, emergency managers and coastal residents have access to tools developed by the U.S. Geological Survey that predict, more precisely than ever, where beach erosion and beachfront flooding will take place during hurricanes and other storms.
First-of-its-kind survey shows that algal toxins are found nationwide
More vital coastal storm-tide information needed to help guide storm response efforts following major storms is now available with the addition of Maine’s newest U.S. Geological Survey installed tide gauge.
Much of the coast from Maine to Virginia is more likely to change than to simply drown in response to rising seas during the next 70 years or so, according to a new study led by the U.S. Geological Survey.
