Between 3 to 9 inches of rain fell within 48 hours across the state of Vermont over four days in July 2023 causing significant flooding and millions of dollars in damage. The high amount of rain caused several rivers to peak at record levels, in some cases exceeding records set during Tropical Storm Irene in 2011. This dashboard compares the high-water marks of the two storms.

The Fairfax Water Quality Dashboard provides access to water quality data from 6 intensive monitoring stations and 15 trend monitoring stations in Fairfax County.

The Hampton Roads Water Quality Dashboard displays data from 12 water-quality monitoring stations across the cities of Chesapeake, Hampton, Newport News, Norfolk, Portsmouth, and Virginia Beach. This application provides access to current conditions at each monitoring station and visualize timeseries plots for continuously monitored parameters collected at each monitoring stations.

This interactive web application displays U.S. Geological Survey (USGS) data-collection locations in the Long Island Sound watershed. Station types include water-quality sampling sites, streamgages, groundwater-level and tidal monitoring sites, and meteorological sites. The sites shown on this map were active data-collection locations from May 2022 to May 2023.

This geonarrative describes the sediment and turbidity monitoring conducted as part of the Chester County - U.S. Geological Survey Cooperative Water Resources Program.

This dashboard application displays nitrogen concentrations and loads in selected Long Island Sound tributaries.

This geonarrative is an interactive online presentation of the USGS Pennsylvania Water Science Center's data collection efforts related to Hurricane Ida. This geonarrative includes a summary of the storm in Pennsylvania, USGS data collection methods, embedded interactive maps of flood extents in 5 southeastern Pennsylvania localities, and visual depictions of the storm’s impact across the state.

A method (commonly referred to as the Frimpter method) was developed in early 1980’s to estimate probable high groundwater levels across Massachusetts. The map and table on the web page linked above provide information on wells in the Massachusetts Observation-Well Network which have been used as index wells.

The Nontidal Network Mapper is a data-driven, interactive narrative that shares the short-term nutrient and suspended-sediment load and trend results for the Chesapeake Bay Program’s non-tidal network (NTN) and provides interactive tools to further examine results.

The Chesapeake Data Catalog Application is designed to allow users to identify and interact with datasets used in and across efforts related to the USGS Chesapeake Bay Watershed studies. Metadata gathered for items included in the Catalog for which this app was developed are intended to inform users of dataset details, indicate best practice
