OTHER DATA AVAILABLE
Information of a more detailed nature than that published for most of the gaging
stations such as discharge measurements, gage-height records, and rating tables
is on file in the district offices. Also most gaging-station records are available
in computer-usable form and many statistical analyses have been made.
Water-quality records also are collected at or near some gaging stations. Data
are obtained on the chemical quality of the stream water, on water temperature, and on
sediment. Under "Remarks" of the station description, reference is made to water-
quality records collected on a regular basis for the station. Results of the data collected
are published in annual water-supply papers entitled "Quality of Surface Waters of the
United States" and in annual reports issued by States beginning with 1964 water year; the
state reports are entitled, "Water Resources Data for (state), Part 2. Water Quality
Records."
Information on the availability of unpublished data, statistical analyses, or quality
of water records, may be obtained from the district offices listed on page 2.
RECORDS OF DISCHARGE COLLECTED BY AGENCIES OTHER
THAN THE GEOLOGICAL SURVEY
Records of discharge have been collected by other agencies at numerous sites
throughout the United States that are not published by the Geological Survey. The
Office of Water Data Coordination, Water Resources Division, U.S. Geological Survey,
Washington, D. C., 20242, maintains an index of such sites. Information on records
available on specific sites can be obtained upon request.
