Rulemaking Rule 7.4 



The Ground Water Commission (Commission) would like to make all interested parties aware that it is initiating the process to possibly amend Rule 7.4 of the Rules and Regulations for the Management and Control of Designated Ground Water (Designated Basin Rules).  The current Designated Basin Rules are available to view and download here.

The proposed change to Rule 7.4 initially proposed by the Staff of the Commission requires that a change of water right consisting of a change of description of irrigated acres may not result in an increase over the historic depletion of the aquifer by a well.  A draft of the initial proposed wording of the rule change is available to view and download here.

In contemplating this rule change 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 proposal under consideration.  Interested parties may participate and present their thoughts, ideas, and reasoned opinions on the proposed change by attending meetings and/or submitting written comments.

Staff of the Commission will hold a public meeting to allow for input on July 18, 2017, at 1:00 p.m., in Room 814, 1313 Sherman St, Denver, CO, 80203.  Interested parties may participate in person or by phone.  Phone attendance can be accomplished by dialing 303-866-3581 x7622.  Additional public meetings may be scheduled as needed.

Written comments should be submitted to Keith Vander Horst, Designated Basins Team Leader, by email to, or by US mail to 1313 Sherman St. Room 821, Denver, CO 80203.  Interested parties are encouraged to submit any written comments prior to the public meeting.

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
