The Impact of Climate Change on Culturally Significant Wetland Plants and Their Habitat in the Meduxnekeag River Watershed in Maine

Wetland plants are important to Wabanaki people in Maine and are central to Houlton Band of Maliseet Indian (HBMI) identity. HBMI peoples have harvested culturally important plants within the Meduxnekeag watershed for generations. Basket making and medicinal plant harvesting are forms of cultural preservation that are also important to Tribal economies. Projections for climate change in the no

Digital Elevation Model and Derivative Datasets to Support the Integration of Stormwater Drainage into the StreamStats Application for the Mystic River Watershed, Massachusetts

The U.S. Geological Survey’s StreamStats program is a publicly-accessible web application (https://streamstats.usgs.gov) that can be used to delineate drainage areas, compute basin characteristics, and estimate flow statistics for user-selected locations on streams. StreamStats services are typically implemented at the statewide or watershed scale (referred to as state or basin applications), and

Computed Streamflow Using Satellite Data for the Copper, Nushagak, Tanana, Yukon, Susitna, and Knik, Koyukuk Rivers, Alaska, 2008-2021

Relations between satellite altimetry water-surface elevation data and dynamic surface water extent data derived from LANDSAT imagery data were used with a modified Manning's equation to compute remotely sensed streamflows (RSQ) at locations on the Tanana, Yukon, Susitna, Nushagak, Copper, Koyukuk and Knik Rivers in Alaska using satellite data.

Data for Models Estimating Baseflow for Streams Containing Endangered Atlantic Salmon in Maine, USA

The U.S. Geological Survey (USGS) developed a regression model for estimating August mean baseflow per square mile of drainage area to help resource managers assess relative amounts of baseflow in streams with Maine Atlantic Salmon habitat. The model was derived from August mean baseflows computed at 31 USGS streamgages in and near the Gulf of Maine Atlantic Salmon Habitat Recovery Units. An ordin

Maine Lidar-Derived Watersheds

Lidar Digital Elevation Models (DEMs) at 2-meter resolution have been used to derive watershed boundaries for the State of Maine. Geographic Information Systems (GIS) software was used to hydrologically enforce lidar DEMs and delineate watershed boundaries at pre-existing pour point locations (Price, 2016). The watershed boundaries are comparable in size to the 12-digit Hydrologic Unit catchments

Data and shapefiles used to document the floods associated with the January and March 2018 Nor'easters for Coastal Areas of New England (ver. 2.0, November 2021)

The U.S. Geological Survey (USGS) New England Water Science Center worked with the Federal Emergency Management Agency to document the floods of January 4, 2018 and March 2-4, 2018, in coastal Massachusetts. USGS conducted a frequency analysis of stillwater elevations at three National Oceanic and Atmospheric Administration coastal gages following the coastal floods of 2018. The data for these an

Transportation Risk Assessment for Planning and Project Delivery (TRAPPD) Python Script Tool for Maine

Over 40,000 road crossings in Maine are maintained by Maine Department of Transportation (MaineDOT) managers, emergency managers, natural resource planners, and municipalities. Resource managers need a way to quickly and comprehensively assess, during the planning stages of potential transportation-related projects, how ecological, hydrologic, and structural characteristics of bridges and culverts

Thirty- and ninety-year data sets of streamflow, groundwater recharge, and snowfall simulating potential hydrologic response to climate change in the 21st century in New Hampshire

Documentation and mapping of flooding from the January and March 2018 nor’easters in coastal New England

In January and March 2018, coastal Massachusetts experienced flooding from two separate nor’easters. To put the January and March floods into historical context, the USGS computed statistical stillwater elevations. Stillwater elevations recorded in January 2018 in Boston (9.66 feet relative to the North American Vertical Datum of 1988) have an annual exceedance probability of between 2 and 1 perce
