This ArcGIS Online Dashboard provides an interactive platform to view drilling waste land application data in Oklahoma.

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.

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

The U.S. Geological Survey collects long-term hydrologic data and conducts scientific research within Long Island Sound and its watershed. This geonarrative summarizes the history, features and the ecological and societal importance of the Long Island Sound and its watershed. It also discusses the ongoing challenges that threaten the Sound’s environmental health.

This interactive geonarrative presents information on how feasible it is to develop a GIS-based hydraulic modeling tool for preliminary culvert designs for stream crossings in Massachusetts.

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.
