Data and hydraulic models at selected dam-removal and culvert-retrofit sites in the northeastern United States Data and hydraulic models at selected dam-removal and culvert-retrofit sites in the northeastern United States
This dataset contains U.S. Geological Survey (USGS) developed hydraulic models, USGS developed hydrology data, US Fish and Wildlife Service (USFWS) supplied data (topography/bathymetry and structure data for pre removal conditions), and USGS field surveyed data at nine dam-removal and culvert-retrofit sites in the northeastern United States (Olson and Simeone, 2021). The hydrology, the...

Hydraulic modeling at selected dam-removal and culvert-retrofit sites in the northeastern United States Hydraulic modeling at selected dam-removal and culvert-retrofit sites in the northeastern United States
Aquatic connectivity projects, such as removing dams and modifying culverts, have substantial benefits. The restoration of natural flow conditions improves water quality, sediment transport, aquatic and riparian habitat, and fish passage. These projects can also decrease hazards faced by communities by lowering water-surface elevations of flood waters and by removing the risk of dam...

Methods for estimating regional coefficient of skewness for unregulated streams in New England, based on data through water year 2011 Methods for estimating regional coefficient of skewness for unregulated streams in New England, based on data through water year 2011
The magnitude of annual exceedance probability floods is greatly affected by the coefficient of skewness (skew) of the annual peak flows at a streamgage. Standard flood frequency methods recommend weighting the station skew with a regional skew to better represent regional and stable conditions. This study presents an updated analysis of a regional skew for New England developed using a...

Development and evaluation of a record extension technique for estimating discharge at selected stream sites in New Hampshire Development and evaluation of a record extension technique for estimating discharge at selected stream sites in New Hampshire
Daily mean discharges are needed for rivers in New Hampshire for the management of instream flows. It is impractical, however, to continuously gage all streams in New Hampshire, and at many sites where information is needed, the discharge data required do not exist. For such sites, techniques for estimating discharge are available. The U.S. Geological Survey, in cooperation with the New...

The Connecticut Streamflow and Sustainable Water Use Estimator—A decision-support tool to estimate water availability at ungaged stream locations in Connecticut The Connecticut Streamflow and Sustainable Water Use Estimator—A decision-support tool to estimate water availability at ungaged stream locations in Connecticut
Freshwater streams in Connecticut are subject to many competing demands, including public water supply; agricultural, commercial, and industrial water use; and ecosystem and habitat needs. In recent years, drought has further stressed Connecticut’s water resources. To sustainably allocate and manage water resources among these competing uses, Federal, State, and local water-resource...

Tropical storm Irene flood of August 2011 in northwestern Massachusetts Tropical storm Irene flood of August 2011 in northwestern Massachusetts
A Presidential disaster was declared in northwestern Massachusetts, following flooding from tropical storm Irene on August 28, 2011. During the storm, 3 to 10 inches of rain fell on soils that were susceptible to flash flooding because of wet antecedent conditions. The gage height at one U.S. Geological Survey streamgage rose nearly 20 feet in less than 4 hours because of the combination...

Flood Map for the Winooski River in Waterbury, Vermont, 2014 Flood Map for the Winooski River in Waterbury, Vermont, 2014
From August 28 to 29, 2011, Tropical Storm Irene delivered rainfall ranging from approximately 4 to more than 7 inches in the Winooski River Basin in Vermont. The rainfall resulted in severe flooding throughout the basin and significant damage along the Winooski River. In response to the flooding, the U.S. Geological Survey (USGS), in cooperation with the Federal Emergency Management...
