• Login with Water Right ID and Reporting Identifier: Letters contained in your Water Right ID or Reporting Identifier need to be capitalized in the login fields. Water Rights ID's usually start with a letter followed by six numbers. Reporting Identifiers are six numbers, letters, or a mix of both.
• Access Multiple Water Rights using an email as your User ID and Password: This method will allow you to use the same User ID (email) and Password to complete all of your water right reporting requirements for those with multiple Water Rights to manage.
• New Multiple Water Rights Users: Connect multiple water rights here. You will need the Water Right IDs (e.g. A012345) and the Reporting Identifiers associated with your water right records.
• If you set up an email account and forgot your password: Reset Password
