The coastal areas of southeastern New York (fig. 1) are highly vulnerable to tidal flooding (fig. 2). Timely evacuation of people from flood-threatened areas in advance of approaching hurricanes and nor'easters (northeast coastal storms) requires adequate flood-warning time. To begin addressing this need for immediate information on coastal flooding, the U.S. Geological Survey (USGS), in cooperation with the Town of Hempstead Department of Conservation & Waterways, Village of Freeport, and New York State Department of Environmental Conservation, has operated a network of real-time tidal water-elevation and meteorological stations since 1997 in the coastal areas of Long Island and New York City. Each tidal water-elevation...

Problem The presence of pathogens in Long Island marine embayments and the hazards they pose to marine resources and human health is of increasing concern. Many waterbodies on the New York State Section 303(d) List of Impaired Waters have pathogens listed as the primary pollutant that are suspected to originate from urban/storm runoff. There is neither a clear understanding of the relative magnitude and geographic origin of sources of loadings of pathogens (from urban/storm runoff, submarine groundwater discharge, etc) on Long Island, nor clear understanding about the host organisms from which they originate (such as human, mammals, or birds). Pathogen loads to specific embayments are affected by watershed land-use,...

The remnants of Hurricane Ida produced significant rainfall over the five boroughs of New York City (NYC) for several hours on September 1st, 2021. The long-duration, high-intensity rainfall resulted in extensive inundation of streets, buildings, subways, and other public spaces. In response to a Federal Emergency Management Agency (FEMA) mission assignment, the U.S. Geological Survey (USGS) identified and surveyed high-water marks (HWMs) at 83 locations across NYC to document the peak water elevation in impacted areas (Capurso and others, 2023). This data release contains maps of water-depth and inundation extents for areas within 250 meters of surveyed HWM locations. These depth maps assume a constant water-surface...

In 2013, the U.S. Geological Survey (USGS) in partnership with the U.S. Federal Highway Administration (FHWA) published a new national stormwater quality model called the Stochastic Empirical Loading Dilution Model (SELDM; Granato, 2013). The model is optimized for roadway projects but in theory can be applied to a broad range of development types. SELDM is a statistically-based empirical model pre-populated with much of the data required to successfully run the application (Granato, 2013). The model uses Monte Carlo methods (as opposed to deterministic methods) to generate a wide range of precipitation events and stormwater discharges coupled with water-quality constituent concentrations and loads from the upstream...

This dataset describes streamflow and precipitation event statistics for four watersheds located in Clarksburg, Maryland, USA. Streamflow and precipitation events were identified from fourteen years of sub-daily (5- and 15-minute) monitoring data from October 1, 2004 through September 30, 2018. A 6-hour inter-event window was used to define discrete streamflow and precipitation events. The following streamflow metrics were calculated for each event area normalized peak streamflow, runoff yield, runoff ratio, streamflow duration, time to peak, and rise rate. Precipitation event metrics include total precipitation depth and precipitation event duration.

This data release documents the data and models used to assess flows, concentrations, and loads of highway and urban runoff and of stormwater within receiving streams in southern New England. There are more than 48,000 locations in southern New England where roads cross streams and many more locations where runoff from developed areas may discharge to receiving streams; information about runoff discharges and the quantity and quality of stormflow upstream and downstream of discharge points is needed to inform resource-management decisions. This analysis was done with a version 1.1.1 of the Stochastic Empirical Loading and Dilution Model (SELDM) that was populated with regional statistics for southern New England....
BACKGROUND The Adirondack region of New York has a history of relatively high atmospheric sulfur (S) and nitrogen (N) deposition (Greaver et al. 2012). Adirondack ecosystems have been impacted by these inputs, including soil and surface water acidification, and impaired health and diversity of forest vegetation and aquatic biota. Air quality management, through the Clean Air Act, the U.S. Environmental Protection Agency NOx Budget Trading Program, and the Clean Air Interstate Rule (CAIR) has resulted in decreases in atmospheric S and N deposition in the Adirondacks and throughout the eastern U.S. (Lehmann et al., 2005), which is driving the recovery of surface waters from past acidification. Section 303(d)...
Four dichloroacetamide herbicide safeners (AD-67, benoxacor, dichlormid, and furilazole) and two co-applied herbicides (acetochlor and metolachlor) were measured in water samples from 7 streams across Iowa and Illinois. Iowa water samples were collected from March 2016 to June 2017, and Illinois water samples were collected from September 2016 to June 2017. The compounds studied are applied to corn, and Iowa and Illinois are the two largest corn producing states in the U.S. The seven stream sites are all adjacent to agricultural fields in corn production. Water samples (1-L) were collected in amber glass bottles using a grab or depth weighted approach. With the exception of one site, Iowa River at Wapello (USGS...

This U.S. Geological Survey data release contains datasets that combine past data with future projections of nitrogen sources and nitrogen export to the Chesapeake Bay watershed for the years 1950-2050. To help understand the effect of human and environmental changes over this time period, data for nitrogen sources from wastewater, agricultural fertilizer and manure, and atmospheric deposition are combined with datasets of population and land use. These datasets were used in conjunction with a previously calibrated SPAtially Referenced Regression On Watershed attributes (SPARROW) modeling tool to estimate the mean annual loads of total nitrogen to the Chesapeake Bay and nontidal stream reaches in the watershed at...
Nitrapyrin, a nitrification inhibitor, 6-CPA, a nitrapyrin degradate, and three co-applied herbicides (acetochlor, atrazine, and metolachlor) were measured in surface drains from eights sites in Illinois. Water samples were collected from April to June 2017. The compounds studied are applied to corn, Illinois is one of the largest corn producing states in the U.S. Water samples (1-L) were collected in amber glass bottles using a grab or depth weighted approach. Water samples were filtered (0.7 micrometers), extracted via solid phase extraction (Oasis® MAX cartridge), and analyzed (nitrapyrin and herbicides by gas chromatography with mass-spectrometry; 6-CPA by liquid chromatography tandem mass-spectrometry).

Nitrogen (N), phosphorus (P), and total suspended solids (TSS) loads, in Hampton Roads, Virginia stormwater conveyance systems have been calculated using monitoring data from 12 intensively monitored watersheds for the period from water year (October - September) 2016 through 2020. Nutrient and TSS loads were computed using a surrogate (multiple-linear regression) approach with lab analyzed N, P, and TSS samples as the response variable and basic water-quality parameters (e.g. turbidity, specific conductance, water temperature), streamflow, a baseflow separation Boolean term, and time and seasonal terms as predictor (surrogate) variables. Load results represent the mass of N, P, and TSS exported from each of the...

Chloride deicers have been applied by the Oregon Department of Transportation (ODOT) to Interstate-5 (I-5) from the Oregon-California border north to mile marker 10 for several years in the high-elevation area known as the Siskiyou Pass. Magnesium chloride (MgCl2) and sodium chloride (NaCl) are applied to keep the interstate safe for drivers and allow for efficient transport of goods and people through adverse weather conditions, particularly snow and ice. The USGS entered into a cooperative agreement with ODOT to research the effects of the application of these chloride deicers in the Carter Creek and Wall Creek watersheds within the Siskiyou Pass. Hydrologic and meteorological data were collected within the study...

Stormwater Action Monitoring (SAM) is a collaborative monitoring program between western Washington municipal stormwater permittees, state and federal agencies. SAM’s role is to use the results of regional monitoring and focused studies to inform policy decisions and identify effective strategies to improve stormwater management in the Puget Sound region. The SAM program includes status and trends monitoring of water quality, stream biota (macroinvertebrates, algae), and stream habitat to measure whether conditions are getting better or worse and identify patterns in healthy and impaired Puget Lowland streams. The first round of status and trends monitoring of Puget lowland streams took place in 2015 and one goal...
This tabular dataset includes precipitation data, inflow and outflow data, and other associated data for a bioretention garden in Douglas County, Nebraska. At the Douglas County Health Center (DCHC) biorentention garden the general monitoring design corresponded to a water balance approach to characterize the inputs, outputs, and change in storage within the bioretention gardens. The components of the water balance that were measured or calculated were precipitation volume, stormwater inflow volume to bioretention garden, overflow volume, and evapotranspiration. The performance of the bioretention gardens was evaluated for a series of rainfall events. The start of an event was determined based on when rainfall began...

Background The proposed study will examine any existing data from the monitoring wells, weather station, and flow through the storm sewer system (supplied by Buffalo Sewer Authority) to determine the dynamics of the system during storm events. Further analysis using all available information is needed to fully understand the relationship of events to the implementation of Green Infrastructure stormwater-control measure effectiveness. Questions to be addressed include: How do pipe flows and groundwater levels respond to storms? Can the data be used to quantify water-budget components at the site? To what extent can the effect of the Green Infrastructure in reducing stormwater volumes and peaks be quantified? Based...
