Data collected at Pawtuckaway Beach in Nottingham, New Hampshire, 2015-2017, including data from Escherichia coli (bacteria) samples, and from USGS meteorological and water-quality stations

In the summer of 2014 at Pawtuckaway Beach at Pawtuckaway State Park in Nottingham New Hampshire, the U.S. Geological Survey (USGS) established a seasonal meteorological station (430508071091801) on the beach and a seasonal water-quality station (01073389) in Pawtuckaway Lake proximal to the swimming area. Data recorded at 15-minute intervals by the meteorological station were wind speed, wind...

Drought 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.

National Water Information System (NWIS) Mapper

The NWIS mapper provides access to over 1.5 million sites contained in the USGS National Water Information System (NWIS), including sites where current and historical surface-water, groundwater, springs, and atmospheric data has been collected. Users can search by site type, data type, site number, or place.

Baseline groundwater-quality data from a densely developed coastal neighborhood, Falmouth, Massachusetts (2016 - 2019)

This data release provides a comprehensive dataset of sampling-site characteristics and baseline groundwater-quality data collected from a network of multilevel sampling wells installed in a densely developed coastal neighborhood undergoing a conversion from onsite septic systems to municipal sewering. Groundwater samples were collected during multiple events from a total of 227 well screens...

Database of Lithostratigraphic Observations and Grain-Size Distributions From a Boring Drilled to Bedrock in Glacial Sediments Near Nantucket Sound in East Falmouth, Cape Cod, Massachusetts

This dataset presents descriptions of sediments collected from a boring drilled to bedrock near Nantucket Sound in East Falmouth, Cape Cod, Massachusetts. There are four types of descriptions—units, features, subsamples, and grain-size distributions: 1) Units correspond to “lithostratigraphic units” described by Hull and others (2019). Units are vertically...

Digital Photographs of Sediment Cores From a Boring Drilled to Bedrock in Glacial Sediments Near Nantucket Sound in East Falmouth, Cape Cod, Massachusetts

This dataset contains high-resolution digital photographs of sediment cores collected from a boring drilled to bedrock near Nantucket Sound in East Falmouth, Cape Cod, Massachusetts. Following collection and transportation to a processing facility, the upper half of each core was scraped to form a flat surface along the length of the core. Digital photographs were taken of 8-inch (20-...

Highway-Runoff Database (HRDB) Version 1.1.0

The Highway-Runoff Database (HRDB) was developed by the U.S. Geological Survey, in cooperation with the Federal Highway Administration (FHWA) to provide planning-level information for decision makers, planners, and highway engineers to assess and mitigate possible adverse effects of highway runoff on the Nation’s receiving waters. The HRDB was assembled by using a Microsoft Access...

Temperature and Seepage Data from the Nearshore Bottom Sediments of Five Groundwater Flow-Through Glacial Kettle Lakes, Western Cape Cod, Massachusetts, 2015-18

Hydrologic data were collected in the nearshore lake-bottom sediments of five lakes on western Cape Cod, Massachusetts: Ashumet (Falmouth), Long (Centerville), Santuit (Mashpee), Shubael (Barnstable), and Snake (Sandwich) Ponds. Water budgets of flow-through glacial kettle lakes are commonly dominated by groundwater flow into and surface-water seepage out of the lake, and inputs and losses...

Observations of Lithostratigraphy and Hydrogeology From a Boring Drilled to Bedrock in Glacial Sediments Near Nantucket Sound in East Falmouth, Cape Cod, Massachusetts

Lithostratigraphic and hydrogeologic observations for the unconfined aquifer of western Cape Cod are limited near coastal groundwater-discharge areas. In spring 2015, a 310-foot-deep boring was drilled and a well was installed to 100 feet below land surface to facilitate detailed study of aquifer characteristics along the southern coast of Cape Cod. Characteristics of interest included the...

InterpretSELDM version 1.0 The Stochastic Empirical Loading and Dilution Model (SELDM) output interpreter

The InterpretSELDM program is a graphical post processor designed to facilitate analysis and presentation of stormwater modeling results from the Stochastic Empirical Loading and Dilution Model (SELDM), which is a stormwater model developed by the U.S. Geological Survey in cooperation with the Federal Highway Administration. SELDM simulates flows, concentrations, and loads in stormflows from...

Polycyclic Aromatic Hydrocarbons (PAHs) in Parking Lot Dust and Pavement Runoff Receptor Sites in Augusta, Maine

The dataset includes results from the analysis of sediments and solids collected from receptor sites receiving runoff from adjacent parking lots and other paved surfaces. Receptor sites include parking lot catch basins, retention ponds, drainage ditches, and storm-water discharge zones in streams and rivers. Samples were analyzed for percent moisture content and concentrations of 17 U.S....

Snow Depth and Snow Water Equivalents at Sleepers River Research Watershed, Danville, Vermont

Snow depth and snow water equivalent (SWE) measurements have been made at Sleepers River Research Watershed starting in 1960. Initial snowpack measurements were made by the Agricultural Research Service joined by the National Weather Service in 1966. Cold Regions Research and Engineering Laboratory started measuring the snowpack in 1979, followed by the U.S. Geological Survey from 1993 to the...
