Consistent, real-time water data from streams, lakes, reservoirs, ground-water, and meteorological sites, are available from the USGS National Water Information System as graphs, tables, or files to download.
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.
Recent physical changes over time, including trends toward earlier snowmelt runoff, decreasing river ice, and increasing spring water temperatures, may affect salmon populations; we want to know how important these effects are.
Locations for nine species of large constrictors, from published sources, along with monthly precipitation and average monthly temperature for those locations. Shapefiles for each snake species studied.
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.
A broad survey of regional patterns in stream flow nationwide. Maps and graphs summarizing streamflow conditions for water-year 2010 (October 1, 2009 to September 30, 2010) in the context of the 81-year period 1930-2010.
