From The Pueblo Chieftain (Matt Hildner):
The rules would help govern how the Engineer’s Office regulates the subdistrict, which is made up of groundwater users in the north-central part of the valley who will tax themselves to buy replacement water for pumping that injures senior surface water rights and to fallow ground in an effort to restore aquifer levels. The rules would also apply to groundwater irrigators who are not part of a subdistrict…
The effective date of the rules also will be pushed back to 2012.
The other pending hurdle for the draft rules will come when the advisory committee gets a look at the response functions of the Rio Grande Decision Support System, a computer program designed to model the flow of the valley’s groundwater. That system may be used to help the Engineer’s Office determine where injuries from pumping will occur and from which wells, but the draft rules allow the office to use other means when it’s determined that reliance on the computer model would be inappropriate.
