Fire Danger Viewer, Map and Data Products

The Map and Data Products page offers bulk download of the Fire Danger Forecast data suite.

Georgia Water Use

The U.S. Geological Survey (USGS) South Atlantic Water Science Center and the Environmental Protection Division of the Georgia Department of Natural Resources have been collecting and compiling water-use information in Georgia since 1980 as part of an ongoing cooperative agreement.

Surface Water Flow Trends in the Nation's Streams and Rivers

Changes in streamflow conditions can affect infrastructure, water supply, and ecosystems. The IWAAs Surface Water Flow Trends mapper provides access to information about long-term changes in low flows, mean flows, and peak flows. View national trends for the last 100, 75, or 50 years, or calculate trend values for a custom time period at an individual site.

Hydrogeology of the Adelaida Area, San Luis Obispo County, CA

The USGS is conducting a comprehensive evaluation of groundwater resources of the Adelaida area. Use this map to explore the hydrogeology of the area, including land use, geology, and USGS hydrologic data by watershed or water management district. 

TrendPowerTool: A web lookup tool for estimating the statistical power of a monitoring program to detect population trends

A simulation-based power analysis can be used to estimate the sample sizes needed for a successful monitoring program, but requires technical expertise and sometimes extensive computing resources. We developed a web-based lookup app, called TrendPowerTool.

Philadelphia Water Quality Monitoring Network

The Philadelphia Water Department (PWD) and USGS have been working together to create and expand the water-quality monitoring network for Philadelphia. Data from these gaging stations will allow PWD scientists and engineers to monitor spatial and temporal water quality/quantity trends in the City in support of watershed restoration initiatives occurring within the City. 

Southwestern Willow Flycatcher Habitat Viewer

The Flycatcher Habitat Viewer was developed to meet the needs of organizations by providing maps of predicted flycatcher breeding habitat throughout its range. Maps are provided from 2013 to present and cover 57 satellite scenes. Maps identify predicted flycatcher habitat based upon the amount of green vegetation within a 120-m radius of each cell, and the size of floodplain within a 360-m radius.

USGS Hydrologic Conditions Network for New York

Hydrologic Conditions Network Map displays Streamflow Monitoring Network, Groundwater Bedrock Aquifer Monitoring Wells, and Groundwater Unconsolidated Aquifer Monitoring Wells in New York State Drought Regions.

Assessing Phytoplankton and Nutrient Abundance in the San Francisco Estuary and Delta

A data visualizatoin exploring the relationship between nutrient distribution and phytoplankton under different conditions across the San Francisco Delta and Estuary. Assessing distribution and abundance aids understanding of how managing nutrient supplies affects aquatic food webs, helping managers evaluate the potential environmental benefits of future nutrient reduction efforts agains

Decision-Making with the Multiple Objective Vireo Explorer (MOViE) Tool for the Santa Clara River

This tool is constructed around a model that integrates the major factors influencing the continued recovery of least Bell's vireo along the Santa Clara River in California (i.e., habitat quantity and configuration, habitat quality, and cowbird parasitism). 

Earth Observation Requirements Evaluation System (EORES)

The Earth Observation Requirements Evaluation System (EORES) provides long-term capability to collect, maintain, and analyze Earth observaton requirements and capabilities using relational databases, user interfaces, and analysis tools.
