Water Resources
Maps
The Water Resources Mission Area creates a wide variety of spatial products from GIS datasets, online mappers and decision-support tools, data visualizations, and traditional static maps.
Mississippi/Atchafalaya River Basin (MARB) SPARROW Mapper, 2002
The mapper displays SPARROW nutrient load and yield data and the importance of various nutrient sources for the MARB, given nutrient inputs similar to 2002. Rankings can be shown by major watershed, state, HUC8, tributary, and catchment. Nutrient data can be explored using maps and interactive graphs and tables. Modeling results can be exported as an Excel spreadsheet or a geospatial dataset.
How much water do we use?

USGS StreamStats
StreamStats is a Web-based tool that provides streamflow statistics, drainage-basin characteristics, and other information for USGS streamgaging stations and for user-selected ungaged sites on streams. When users select the location of a streamgaging station, StreamStats provides previously published information from a database. When users select a site on an ungaged stream,
U.S. Geological Survey Flood Inundation Mapping Science
Static flood-inundation map libraries consist of maps that have been created in advance of a flood that are ready to be served through the Internet. Each library consists of a set of flood extent and depth maps developed for predetermined stream stage intervals (for example, a map for each one foot of stage).
NAWQA Nao
The goals of the NAWQA program are being achieved through ongoing or planned investigations of 59 of the Nation's most important river and aquifer systems, which are referred to as study units. These study units were selected to represent the diverse geography, water resources, and land and water uses of the Nation. The Mobile River Basin is one such study unit, designed to supplement water.
