Streamflow statistics and basin characteristics for most streams in specific US states using the Streamstats program. Data for areas can be selected from interactive maps and by an automated process. Includes a tutorial.
Consistent, historic, and up-to-date surface-water data, such as gage height (stage) and streamflow (discharge), collected at major rivers, lakes, and reservoirs, downloadable from the USGS National Water Information System as graphs, tables, or files.
Photos, publicatons and recordbreaking flood peaks from the flood that included 9 states, the Mississippi and Missouri Rivers, and completely inundated 75 towns.
Upcoming interagency study to assess status of ecological conditions, their relationships with contaminants and nutrients, anthropogenic factors affecting these, and develop models that may predict these ecological conditions.
Explains the characteristics and history of this distinctive way of describing geographic position characteristic of the midwestern and western states of the US.
Summary of part of the USGS interdivisional Mississippi Basin Carbon project that will study the changes in climate and the environment through carbon cycle changes recorded in lake sediments in the Upper Mississippi River Basin.
This updated subset of USGS streamgages for which the streamflow primarily reflects prevailing meteorological conditions for specified years, screened to exclude sites where human activity affects the natural flow of the watercourse.
We use moderate resolution satellite data to assess live fuel condition for estimating fire danger. Using 23 years of vegetation condition measurements, we are able to determine the relative greenness of wildland vegetation susceptible to burning.
