State Water & Monitoring Well Repository
Overview
The Department is the steward for low temperature water and monitoring well location data for the state.  In this capacity it hosts a repository of water well locations as defined by the Oregon Water & Monitoring Well Standard. In 2010, OWRD worked with several other state and local agencies, with input from federal and private entities, to create the state GIS standard.  It is intended to provide a link between the various water well data sets in Oregon.  So far, OWRD has populated it with its own well data for those locations with a latitude & longitude coordinate.  The objective is to incorporate water well location data from other agencies in Oregon that maintain information about water wells for their business.

Links to water/monitoring well data from other agencies in Oregon
Other agencies in Oregon also maintain their own water well data.  Here are links to some of those data sets:
 
Oregon Department of Environmental Quality:  Link to LASARWeb application
 
Oregon Health Authority:  The Oregon Drinking Water Program's Data Online tool allows access to information on public water systems in Oregon.  This tool contains data collected from wells, springs, and surface water intakes that are used to supply drinking water through more than three service connections or that is used by 10 or more people per day.  Data includes coliform test results, chemical test results, contacts, violations, enforcements, public notices, and basic water system information.  Many of the wells in the Data Online tool are identified by Water Resources Department Well Log Numbers and/or Well Tag Numbers.  However, it should be understood that, as a matter of water system security, public water supply well locations are not available on this website.  Therefore, water quality data can only be linked to specific wells if Public Water System ownership of the well has been determined prior to using the Data Online tool.
