Water Resources Explorer

Water right records can be searched on the Water Resources Explorer by:

  • Document/record number.
  • The name of the person to whom the water right was issued.
  • The name of the claimant, if it is a water right claim.

The web map is an efficient tool for anyone researching water rights or water right claims, or seeking to obtain a water right in Washington state. Consultants, real estate agents, local government staff, elected officials, and holders of existing water rights will find the map a valuable source of information.

The web map section and/or quantity report section allows users to query and view data and documents relating to water rights and claims. This includes, if completed, the mapped place of water use and water sources (existing and proposed) for water right certificates, water use permits, applications for water use, and claims of water use as described on the documents maintained by us.

Links to water right documents allow the user access to scanned images of water resource documents that include:

  • Water right certificates, water use permits, applications for water use, and claims of water use
  • The authorized, claimed, or requested quantity of water (both current and annual) and number of irrigated acres
  • The purpose of water use, priority date or date of first use, as well as the name of record
  • Information regarding metering, if required
  • Information not maintained directly by us or USGS flow data from stream gauging stations
