Ohio Water Science Center - Annual Water Data Reports

Ohio River Basin (Vol 1) and St. Lawrence River Basin (Vol 2)

The Water Resources Division of the U.S. Geological Survey (USGS), in cooperation with state agencies, obtains a large amount of data each water year (a water year is the 12-month period from October 1 through September 30 and is identified by the calendar year in which it ends) pertaining to the water resources of Ohio. These data, accumulated during many years, constitute a valuable data base for developing an improved understanding of the water resources of the State. To make these data readily available to interested parties outside the USGS, they are published annually in this report series entitled "Water Resources Data---Ohio."

This report (in two volumes) includes records on surface water and ground water in the State containing:
(1) discharge records for streamflow-gaging stations, miscellaneous sites, and crest-stage stations, 
(2) stage and content records for streams, lakes, and reservoirs, 
(3) water-quality data for streamflow-gaging stations, wells, synoptic sites, and partial-record sites, and 
(4) water-level data for observation wells. 

The data in this report represent that part of the National Water Data System collected by the USGS and cooperating State and Federal agencies in Ohio.

This series of annual reports for Ohio began with the 1961 water year with a report that contained only data relating to the quantities of surface water. For the 1964 water year, a similar report was introduced that contained only data relating to water quality. Beginning with the 1975 water year, the report was changed to present (in two to three volumes) data on quantities of surface water, quality of surface and ground water, and ground-water levels.
