Feb 2008

  • Water-quality data now updated nightly if changes occur in the USGS Water Science Centers' NWIS Database.
  • Updated Automated Retrievals web page to show how to do water-quality retrievals.
  • It is now possible to search for water-quality data at the national level using data attributes.
  • Monthly statistics now calculated over user specified time period instead of limited by USGS defined statistical summary period.
  • Date format now output in user selected sequence for measurements and daily values.
  • Now displays graphs of today's data for sites on other side of international dateline.
  • "Site Home Page" from pulldown menu has now been renamed to "SUMMARY OF ALL AVAILABLE DATA".
  • Instantaneous value tab-separated data outputs now have masking periods applied correctly.
  • Latitude/Longitude searching for sites on other side of international dateline should now work correctly (negative longitudinal values).
  • Added new current condition┬áparameter codes:
    • 00048 Total partial pressure of dissolved gases, water, unfiltered, percent of saturation
    • 00197 Evaporation, accumulated, inches
    • 72036 Reservoir storage, thousand acre feet
    • 72125 Atmospheric water vapor pressure, calculated, kilopascals
  • Surface water measurements are now redirected to the nwis.waterdata system.
  • Precipitation accumulation periods are now calculated based upon current date and time rather then the result date of the data for the first site on the page.
  • Added documentation for current_rating_nu in the Surface Water help section.
  • Fixed issue where groundwater level graphs were not being created.
  • Updated water quality method code documentation.
  • Improved Taxonomic units documentation.
  • Updated rdb header text for water-quality tab separated data outputs.
  • Period of record is now used if no begin date is specified but an end date is specified for water-quality searching.
  • Multiple masking periods are now correctly being applied for Daily Value data.
  • Removed GW tutorial Link.
  • Parameter code searching will now match regardless of case for parameter name and group name.
  • Calendar/water year properly displayed in annual statistic tab-separated (rdb) outputs.
  • Sites with a mean value of .0 should now display that value correctly.
