High-water marks from tropical storm Irene for selected river reaches in northwestern Massachusetts, August 2011 High-water marks from tropical storm Irene for selected river reaches in northwestern Massachusetts, August 2011
A Presidential Disaster Declaration was issued for Massachusetts, with a focus on the northwestern counties, following flooding from tropical storm Irene on August 28–29, 2011. Three to 10 inches of rain fell during the storm on soils that were susceptible to flash flooding because of wet antecedent conditions. The gage height at one U.S. Geological Survey (USGS) streamgage rose nearly...

Estimates of future inundation of salt marshes in response to sea-level rise in and around Acadia National Park, Maine Estimates of future inundation of salt marshes in response to sea-level rise in and around Acadia National Park, Maine
Salt marshes are ecosystems that provide many important ecological functions in the Gulf of Maine. The U.S. Geological Survey investigated salt marshes in and around Acadia National Park from Penobscot Bay to the Schoodic Peninsula to map the potential for landward migration of marshes using a static inundation model of a sea-level rise scenario of 60 centimeters (cm; 2 feet). The...

Simulation of groundwater conditions and streamflow depletion to evaluate water availability in a Freeport, Maine, watershed Simulation of groundwater conditions and streamflow depletion to evaluate water availability in a Freeport, Maine, watershed
In order to evaluate water availability in the State of Maine, the U.S. Geological Survey (USGS) and the Maine Geological Survey began a cooperative investigation to provide the first rigorous evaluation of watersheds deemed "at risk" because of the combination of instream flow requirements and proportionally large water withdrawals. The study area for this investigation includes the...

Simulation of streamflow in the Pleasant, Narraguagus, Sheepscot, and Royal Rivers, Maine, using watershed models Simulation of streamflow in the Pleasant, Narraguagus, Sheepscot, and Royal Rivers, Maine, using watershed models
The U.S. Geological Survey (USGS) began a study in 2008 to investigate anticipated changes in summer streamflows and stream temperatures in four coastal Maine river basins and the potential effects of those changes on populations of endangered Atlantic salmon. To achieve this purpose, it was necessary to characterize the quantity and timing of streamflow in these rivers by developing and

Inventory and protection of salt marshes from risks of sea-level rise at Acadia National Park, Maine Inventory and protection of salt marshes from risks of sea-level rise at Acadia National Park, Maine
Recent U.S. Geological Survey (USGS) climate studies in the northeastern United States have shown substantial evidence of climate-related changes during the last 100 years, including earlier snowmelt runoff, decreasing occurrence of river ice, and decreasing winter snowpack. These studies related to climate change are being expanded to include investigation of coastal wetlands that might...

Hydrogeomorphic Classification of Wetlands on Mt. Desert Island, Maine, Including Hydrologic Susceptibility Factors for Wetlands in Acadia National Park Hydrogeomorphic Classification of Wetlands on Mt. Desert Island, Maine, Including Hydrologic Susceptibility Factors for Wetlands in Acadia National Park
The U.S. Geological Survey, in cooperation with the National Park Service, developed a hydrogeomorphic (HGM) classification system for wetlands greater than 0.4 hectares (ha) on Mt. Desert Island, Maine, and applied this classification using map-scale data to more than 1,200 mapped wetland units on the island. In addition, two hydrologic susceptibility factors were defined for a subset...

Using hydrogeomorphic criteria to classify wetlands on Mt. Desert Island, Maine – Approach, classification system, and examples Using hydrogeomorphic criteria to classify wetlands on Mt. Desert Island, Maine – Approach, classification system, and examples
A wetland classification system was designed for Mt. Desert Island, Maine, to help categorize the large number of wetlands (over 1,200 mapped units) as an aid to understanding their hydrologic functions. The classification system, developed by the U.S. Geological Survey (USGS), in cooperation with the National Park Service, uses a modified hydrogeomorphic (HGM) approach, and assigns...

August Median Streamflow on Ungaged Streams in Eastern Aroostook County, Maine August Median Streamflow on Ungaged Streams in Eastern Aroostook County, Maine
Methods for estimating August median streamflow were developed for ungaged, unregulated streams in the eastern part of Aroostook County, Maine, with drainage areas from 0.38 to 43 square miles and mean basin elevations from 437 to 1,024 feet. Few long-term, continuous-record streamflow-gaging stations with small drainage areas were available from which to develop the equations; therefore...

Hydrologic Data Collected in Small Watersheds on Mount Desert Island, Maine, 1999-2000 Hydrologic Data Collected in Small Watersheds on Mount Desert Island, Maine, 1999-2000
The US Geological Survey, in cooperation with Acadia National Park, began collecting data for two projects related to nutrient loading to coastal estuaries on Mount Desert Island in 1999. Streamflow data from 16 sites and chemical concentration data from 14 sites in 13 small watersheds on the island are presented in this report. Data were collected from January 1999 to September 2000...

Desert Island, and estimated ground-water use, recharge, and dilution of nitrogen in septic waste in the Bar Harbor area, Maine
In 2002, the U.S. Geological Survey, in cooperation with the town of Bar Harbor, Maine, and the National Park Service, conducted a study to assess the quantity of water in the bedrock units underlying Mt. Desert Island, and to estimate water use, recharge, and dilution of nutrients from domestic septic systems overlying the bedrock units in several watersheds in rural Bar Harbor. Water...

Hydrologic data were collected at the Eastland Woolen Mill Superfund Site, Corinna, Maine, from March 19, 1999 through June 11, 1999 as part of a study to formulate a geologic characterization and conceptual model of this study area. Data-collection consisted of measurements of water-surface elevations at 7 surface-water sites and 20 wells.
