Adjudication

The purpose of a water right adjudication is to catalog and confirm through the court all water rights and to which property those water rights belong, binding all property owners and parties to the court decree of those water rights.


The mission of the IDWR Adjudication Section is to determine the water rights accurately in the Snake River Basin Adjudication and the Northern Idaho Adjudication.


Snake River Basin Adjudication (SRBA)

The SRBA was an administrative and legal process that began in 1987 to determine the water rights in the Snake River Basin drainage. The Final Unified Decree for the SRBA was signed on August 25, 2014, and that decree can be viewed at srba.idaho.gov.


Northern Idaho Adjudication (NIA)

Discovering the value of certainty in water right decrees, the State instructed IDWR to move forward with an administrative and legal process to determine the water rights in Idaho's panhandle in three separate adjudications, creating the Northern Idaho Adjudcation. On November 12, 2008, the district court ordered the commencement of the Coeur d'Alene-Spokane River Basin Adjudication (CSRBA). This is phase 1 of the NIA and it covers the Coeur d'Alene-Spokane River water system, which includes the sole source supply of the Spokane Valley-Rathdrum Prairie Aquifer.
