Update the Water Right Query System to be a user-friendly tool that easily provides access to full, accurate, detailed information about Montana water rights.

In October 2023, the Water Resources Division decommissioned the legacy, end-of-life WRQS and made the new WRQS publicly available. The same database that served the legacy WRQS continues to serve the new WRQS application, using the same data. The difference is an improved user interface and a sustainable, scalable platform with capabilities to support additional planned enhancements.

The WRQS project team faced a complex build, issues with the end-of-life legacy system, and a compressed timeline. Given these challenges, the dynamic nature of Montana water rights, and the diversity of the WRQS’s use, some updates are still considered work-in-progress. There will be continuous testing and improvements over the coming months. In addition to improving the public experience, these 2023 updates lay the foundation for additional functionality being built for 2024:

  • Provide general abstracts of all versions of water rights.
  • Provide Final Decree Abstract when complete.
  • Map building tools to assist with water right applications.
  • One central webpage (hub) for all water management resources.


We'll be summarizing new deployments to the WRQS in the DNRC Water News "Online Tools Newsletter."
