The Nevada Division of Water Resources (NDWR) is pleased to announce the release of the 2025 Water Right Map Guidelines, now available on the NDWR website under Library → Informational Guides. These guidelines set the requirements for preparing maps that support water right filings, including applications, proofs of appropriation, proofs of beneficial use, and relinquishments. The update is intended to make map preparation clearer, reduce corrections and rejections, and help ensure consistency in the review and filing process.
Effective Date:
All water right maps submitted for which surveys were completed after October 31, 2025, must comply with the new guidelines. Surveyors are welcome to begin using the updated guidelines immediately.
Informational Session:
To assist with the transition, NDWR will host a virtual informational session to review the changes and answer questions:
