New England Drought Information
Science Center Objects
Current streamflow and ground water conditions are shown to help with understanding the extent and severity of the drought in New England. These maps are updated daily.
This is a static map, however the map from the USGS Water Watch website shows the 7-day average streamflow conditions in hydrologic units. Thus, the map shows conditions adjusted for this time of the year.
The colors represent 7-day average streamflow percentiles for the day of the year. USGS sites having at least 30 years of record are used.
The data used to produce this map are provisional and have not been reviewed or edited. They may be subject to significant change.

This is a static map, however the map on the USGS WaterWatch page shows the current real-time streamflow conditions for New England stations.
The colors represent the real-time streamflow compared to percentiles of historical daily streamflow for the day of the year. Only streamgages with at least 30 years of record are used.
The data used are provisional and have not been reviewed or edited. They may be subject to significant change.

Date published: October 28, 2020Status: CompletedNew 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.

2020 drought in New England
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 drought, reflecting its quick onset. The U.S. Geological Survey (USGS) recorded record-low streamflow and groundwater levels throughout the region. In September, the U.S....

Meeting the challenge: U.S. Geological Survey North Atlantic and Appalachian Region fiscal year 2020 in review
The utilization, preservation, and conservation of the Nation’s resources requires well-informed management decisions. The North Atlantic and Appalachian Region (NAAR) of the U.S. Geological Survey (USGS) supports science-based decision making for Federal, State, and local policymakers to meet the challenges of today and into the future. The...
Enhancement of primary production during drought in a temperate watershed is greater in larger rivers than headwater streams
Drought is common in rivers, yet how this disturbance regulates metabolic activity across network scales is largely unknown. Drought often lowers gross primary production (GPP) and ecosystem respiration (ER) in small headwaters but by contrast can enhance GPP and cause algal blooms in downstream estuaries. We estimated ecosystem metabolism across...

Tropical river suspended sediment and solute dynamics in storms during an extreme drought
Droughts, which can strongly affect both hydrologic and biogeochemical systems, are projected to become more prevalent in the tropics in the future. We assessed the effects of an extreme drought during 2015 on stream water composition in the Luquillo Mountains of Puerto Rico. We demonstrated that drought base flow in the months leading up to the...

Flood- and drought-related natural hazards activities of the U.S. Geological Survey in New England
The U.S. Geological Survey (USGS) has many ongoing and recent water-related natural hazard activities in New England that can be used to help mitigate the effects of natural hazards in cooperation with other agencies. The themes related to potential hazards and the tools and science to better understand and address them include the following:...

Hydrologic Drought Decision Support System (HyDroDSS)
The hydrologic drought decision support system (HyDroDSS) was developed by the U.S. Geological Survey (USGS) in cooperation with the Rhode Island Water Resources Board (RIWRB) for use in the analysis of hydrologic variables that may indicate the risk for streamflows to be below user-defined flow targets at a designated site of interest, which is...

Drought Conditions in Maine, 1999-2002: A Historical Perspective
Hydrologic drought can be defined as reduced streamflow, declining ground-water levels, and (or) reductions in lake or reservoir levels. Monthly precipitation totals, annual 7-day low-flow surface-water recurrence intervals, and month-end ground-water levels from drought years 1999-2002 show that 1999-2002 was the driest period of hydrologic...

Date published: April 9, 2019Drought Streamflow Probabilities in Northeast Region
Maximum likelihood logistic regression (MLLR) is used to estimate drought probabilities for selected Northeast rivers and streams. Winter streamflows are used to estimate the chance of hydrologic drought during summer months. This application allows the display and query of these drought streamflow probabilities for Northeastern streams.

Why doesn't a drought end when it rains?
Rainfall in any form will provide some drought relief. A good analogy might be how medicine and illness relate to each other. A single dose of medicine can alleviate symptoms of illness, but it usually takes a sustained program of medication to cure an illness. Likewise, a single rainstorm will not break the drought, but it might provide temporary... -
When does a drought begin and end?
The beginning of a drought is difficult to determine. Several weeks, months, or even years might pass before people know that a drought is occurring. The end of a drought can occur as gradually as it began. The first evidence of drought is usually seen in records of rainfall. Within a short period of time, the amount of moisture in soils can begin... -
Where in the Nation are droughts or very low flows occurring now? How can I see these sites on a map and get to the data?
To view the USGS streamflow information on drought, see the drought map on our WaterWatch site, which shows below-normal, 7-day average streamflow compared to historical streamflow for the United States. Links to additional maps and drought data are listed on our Drought website and the U.S. Drought Portal . -
What causes drought?
A drought is a period of drier-than-normal conditions that results in water-related problems. The amount of precipitation at a particular location varies from year to year, but over a period of years, the average amount is fairly constant. In the deserts of the Southwest, the average precipitation is less than 3 inches per year. In contrast, the...
