Adjudication

Why is my basin being adjudicated?

The purpose of the general adjudication of water rights is to make a complete and accurate record of all existing water rights.  IDWR must have this list to deliver water to those who are entitled to it when disputes arise. Also, the list is needed to estimate how much water is available for future development.  The reason for determining all water rights in one single large adjudication is to obtain a single decree which is binding for everyone.

How do I know if I should file a claim?

A Notice of Claim should be filed for all water rights including unrecorded water rights (established through historic use by the diversion and application of water to a beneficial use), previously decreed or licensed rights, or water right permits if proof of beneficial use was filed on or before the commencement of the Adjudication.

Water users of a small domestic and/or stockwater (“D&S”) right, as defined by Idaho Code §§ 42-111 & 42-1401A, may elect to file a Notice of Claim now or defer (postpone) the filing until a later time in this proceeding.

If you receive your water from a city system, water district, or water delivery organization, that entity should file for your use.  You can verify that your water delivery organization filed a claim by using the Idaho Department of Water Resources water right search tool, or by contacting your water delivery organization.
