Long Island Depth to Water Viewer 2010
USGS collects groundwater data at varying measurement frequencies to monitor the hydrologic conditions on Long Island, New York. Each year during April and May, the USGS conducts a synoptic survey of water levels to define the spatial distribution of the water table and potentiometric surfaces within the three main water-bearing units underlying Long Island.
Groundwater Conditions on Long Island, New York in 2010
USGS online mapper for water-table altitude, and potentiometric surface of the Magothy, Jameco, Lloyd, and North Shore aquifers on Long Island, NY, in 2010.
MODFLOW
MODFLOW is the USGS's three-dimensional (3D) finite-difference groundwater model. MODFLOW is considered an international standard for simulating and predicting groundwater conditions and groundwater/surface-water interactions.
SPARROW
SPARROW (SPAtially-Referenced Regression On Watershed attributes), is watershed based and designed for use in predicting long-term average values of water characteristics, such as concentrations and amounts of selected constituents that are delivered to downstream receiving waters.
Hazard Exposure Reporting and Analytics (HERA)
The Hazard Exposure and Reporting Analytics (HERA) website helps communities understand how natural hazards could impact their land, people, infrastructure, and livelihoods. HERA provides tools and data to help communities as they plan and prepare for natural hazards.

North American Aquatic Macroinvertebrate Digital Reference Collection (NAAMDRC)
Aquatic invertebrates are a key component of freshwater ecosystems, and an understanding of aquatic invertebrate taxonomy is central to freshwater science. The North American Aquatic Macroinvertebrate Digital Reference Collection (NAAMDRC) was created by the USGS Aquatic Experimental Lab (AXL) to provide users with high-quality digital microscopy photographs.
APPLICATION - Discharge, Sediment, and Water Quality Monitoring Application
This link launches the Grand Canyon Monitoring and Research Center’s discharge, sediment and water quality monitoring application gateway. Sediment and water quality information can be accessed from here for our on-going monitoring taking place across the Southwest U.S.
Tracking Water Quality of the Nation's Streams and Rivers
An online graphical data tool provides annual summaries of nutrient and sediment concentrations and loads and streamflow information for 106 sites monitored as part of the USGS National Water-Quality Network for Streams and Rivers.
Photographs of Willow Creek Reservoir near Heppner, OR
Interactive photograph viewer used to see changes to Willow Creek Reservoir. Includes 5 cameras. Best viewing starts after September 17, 2016.
FishVis Mapper
The FishVis Mapper is the product of an Upper Midwest and Great Lakes LCC project, “A Regional Decision Support Tool for Identifying Vulnerabilities of Riverine Habitat and Fishes to Climate Change” that developed an approach for predicting fish species occurrence under current climate conditions and project how fish species occurrence may change under future climate conditions.
