Environmental streamflows in the United States: historical patterns and predictions

The term environmental streamflows refers to the magnitude, frequency, seasonal timing, duration, and rate of change of streamflows needed to sustain freshwater and estuary ecosystems and human wellbeing. It is important that environmental streamflow assessments by water managers consider changes in climate, land use, and water management; this cannot be done effectively without understanding...

Remembering Tropical Storm Irene in New England

On August 28, 2011 Tropical Storm Irene made landfall in New England, leading to coastal storm surge, significant riverine flooding, sediment transport to Long Island Sound, and major infrastructure damage and destruction. Ten years later, the USGS New England Water Science Center looks back at Irene, the data collected by our Center during the event, the response by our employees before, during...

Long-Term Data Collection Provides Insight to Changes in Water Resources in New England

Primarily through the efforts of Glenn Hodgkins and Robert Dudley, the New England Water Science Center has been studying historical changes in streamflows, groundwater levels, and lake ice in New England and across the country for 20 years. Glenn and Rob have analyzed a wealth of historical data, including 100+ years of streamflow data and 150+ years of lake-ice data at some locations...

New England Drought, 2020

Below average and infrequent rainfall from May through September 2020 led to an extreme hydrologic drought across much of New England, with some areas experiencing a flash (quick-onset) drought.

New England Drought Information

Droughts are one of the most expensive and damaging hydrologic hazards in the United States. They are generally slow in developing, frequently occur over a long period of time, and can affect large areas and populations.

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 and...
