Flood frequency and source data used in the regional regression analysis of annual peak flows in Connecticut (2020) (ver. 2.0, April 2021) Flood frequency and source data used in the regional regression analysis of annual peak flows in Connecticut (2020) (ver. 2.0, April 2021)
Current estimates of the magnitude and frequency of floods at gaged and ungaged stream sites are critical for assessing flood risk, delineating flood zones, designing hydraulic structures, and managing flood plains. The Connecticut Department of Transportation collaborated with U.S. Geological Survey (USGS) in a study to improve the flood-frequency estimates in Connecticut and develop...
Results of peak-flow frequency analysis and regionalization for selected streamgages in or near Maine, based on data through water year 2019 Results of peak-flow frequency analysis and regionalization for selected streamgages in or near Maine, based on data through water year 2019
The U.S. Geological Survey (USGS) recently completed a report documenting methods for peak-flow frequency analysis following implementation of the Bulletin 17C guidelines (https://doi.org/10.3133/tm4B5). The methods provide estimates of peak-flow quantiles for 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs) for selected streamgages operated by the...
Nitrogen concentrations and loads and seasonal nitrogen loads in selected Long Island Sound tributaries, water years 1995-2016 Nitrogen concentrations and loads and seasonal nitrogen loads in selected Long Island Sound tributaries, water years 1995-2016
This U.S. Geological Survey data release presents tabular data on nitrogen concentrations and loads for multiple nitrogen species, and river discharge data used in the analysis of data collected from October 1994 to September 2016. Data on flow and nitrogen concentrations were analyzed using the USGS EGRET R package, and the method of WRTDS (Weighted Regression on Time Discharge and...
Borehole, Surface and Water-Borne Geophysical Surveys at the Callahan Mine Superfund Site in Brooksville, Maine: October 2016 to July 2018 Borehole, Surface and Water-Borne Geophysical Surveys at the Callahan Mine Superfund Site in Brooksville, Maine: October 2016 to July 2018
From October 2016 to July 2018, the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers and Maine Department of Transportation, collected surface, marine and borehole geophysical surveys to characterize the subsurface materials on land and under the water at a former mine facility in Brooksville, Maine. Three water-based geophysical methods were used to evaluate...
Modeled and observed trends at reference basins in the conterminous U.S. from October 1, 1983 through September 30, 2016 Modeled and observed trends at reference basins in the conterminous U.S. from October 1, 1983 through September 30, 2016
This data release contains trend results computed on the basis of modeled and observed daily streamflows at 502 reference gages across the conterminous U.S. from October 1, 1983 through September 30, 2016. Modeled daily streamflows were computed using the deterministic Precipitation Runoff Modeling System (PRMS), and five statistical techniques: Nearest-Neighbor Drainage Area Ratio...
Worksheet for computing annual exceedance probability flood discharges and prediction intervals at stream sites in Connecticut Worksheet for computing annual exceedance probability flood discharges and prediction intervals at stream sites in Connecticut
The U.S. Geological Survey (USGS), in cooperation with Connecticut Department of Transportation, completed a study to improve flood-frequency estimates in Connecticut. This companion data release is a Microsoft Excel workbook for: (1) computing flood discharges for the 50- to 0.2-percent annual exceedance probabilities from peak-flow regression equations, and (2) computing additional...

Simulation of groundwater flow in the regional aquifer system on Long Island, New York, for pumping and recharge conditions in 2005–15 Simulation of groundwater flow in the regional aquifer system on Long Island, New York, for pumping and recharge conditions in 2005–15
A three-dimensional groundwater-flow model was developed for the aquifer system of Long Island, New York, to evaluate (1) responses of the hydrologic system to changes in natural and anthropogenic hydraulic stresses, (2) the subsurface distribution of groundwater age, and (3) the regional-scale distribution of groundwater travel times and the source of water to fresh surface waters and...

Quality of data from the U.S. Geological Survey National Water Quality Network for water years 2013–17 Quality of data from the U.S. Geological Survey National Water Quality Network for water years 2013–17
Water samples from 122 sites in the U.S. Geological Survey National Water Quality Network were collected in 2013–17 to document ambient water-quality conditions in surface water of the United States and to determine status and trends of loads and concentrations for nutrients, contaminants, and sediment to estuaries and streams. Quality-control (QC) samples collected in the field with...

Considerations for incorporating quality control into water quality sampling strategies for the U.S. Geological Survey Considerations for incorporating quality control into water quality sampling strategies for the U.S. Geological Survey
This report describes considerations for incorporating routine quality-assessment and quality-control evaluations into U.S. Geological Survey discrete water-sampling programs and projects. U.S. Geological Survey water-data science in 2020 is characterized by robustness, external reproducibility, collaborative large-volume data analysis, and efficient delivery of water-quality data...

Meeting the challenge: U.S. Geological Survey North Atlantic and Appalachian Region fiscal year 2020 in review Meeting the challenge: U.S. Geological Survey North Atlantic and Appalachian Region fiscal year 2020 in review
The utilization, preservation, and conservation of the Nation’s resources requires well-informed management decisions. The North Atlantic and Appalachian Region (NAAR) of the U.S. Geological Survey (USGS) supports science-based decision making for Federal, State, and local policymakers to meet the challenges of today and into the future. The science centers in the NAAR have well-deserved

Estimating flood magnitude and frequency on gaged and ungaged streams in Maine Estimating flood magnitude and frequency on gaged and ungaged streams in Maine
Accurate estimates of flood frequency and magnitude on rivers and streams in Maine are a key component of effective flood risk management, flood mitigation, and flood recovery programs for the State. Flood-frequency estimates are published here for 148 streamgages in and adjacent to Maine. Equations are provided for users to compute flood-frequency estimates at any location on a stream...
