DWR > Ground Water > Designated Basins (CGWC) > CGWC Documents > Rulemaking Designated Basins


The Ground Water Commission (Commission) would like to make all interested parties aware that it is undertaking a general review of the Rules and Regulations for the Management and Control of Designated Ground Water (Designated Basin Rules).  This process was initiated under directives from the Governor and Division of Natural Resources requiring regulatory efficiency reviews.  The current Designated Basin Rules are available to view and download here.

Staff of the Commission has drafted initial proposed changes to the Designated Basin Rules.  A draft of the initial proposed wording of the changes to each rule proposed to be changed, including the reason for each proposed change, is available to view and download here.

In contemplating these changes to the Designated Basin Rules, the Commission hereby invites participants with an interest in the subject of the rulemaking to submit views or otherwise participate informally in conferences on the proposals under consideration.  Interested parties may participate and present their thoughts, ideas, and reasoned opinions on the proposed changes by attending meetings and/or submitting written comments.

Staff of the Commission held public meetings to allow for input on November 13 and December 18, 2017 and has been accepting written comments on the proposed amendments.  Those who desire to provide additional written comments for Staff to consider in its next draft of the proposed amendments should submit them by January 18, 2018. 

Written comments should be submitted to Keith Vander Horst, Chief of Water Supply, Basins, by email to, or by US mail to 1313 Sherman St. Room 821, Denver, CO 80203.  Written comments that have been submitted regarding changes to the Designated Basin Rules are available to view and download here.

Upon modifying its proposed amendment, Staff plans on scheduling additional public meetings to allow for additional input.  Notice of those meetings will be provided as they are scheduled.

This web page will be updated with additional information on the rulemaking process as it becomes available.  We will also be using email to keep in contact with any interested party that wishes to receive notifications and updates on the process.  Anyone may be added to the email notification list by emailing
