The Rio Grande Water Conservation District, Rio Grande Water Users Association, Conejos Water Conservancy District, State Engineer, and Farming Technology Corporation filed Supporters’ Motion to Amend Decree on July 8. The following day, the senior water users filed notices of appeal to Colorado’s higher courts in two closely associated water and civil cases.
The senior water users’ attorneys contended in their appeals that the amended plan, and the judge’s conditions regarding its approval, still did not provide enough protections for senior water rights. They contended that injury would continue to occur to senior water rights as long as wells were allowed to pump within the sub-district area without state curtailment. They stated that such pumping constituted out of priority depletions. They also questioned whether the water management plan was complete, comprehensive and detailed enough and whether it complied with Senate Bill 04-222 and Colorado law…
Objectors also questioned whether the trial court erred in:
• determining that the plan of water management need not contain sufficient terms and conditions for the trial court to determine “no injury” to other water rights as a result;
• delegating to the sub-district and state and division engineers the authority to determine “annual replacement plans” to replace depletions from sub-district well pumping;
• deferring a finding regarding whether the plan of water management will result in injury to other water rights and instead relying on retained jurisdiction over the plan;
• approving the use of response function, a method for determining water injuries;
• determining that a plan of water management may use a reduction in the amount of water consumed by native vegetation to increase the quantity of water available to be pumped by sub-district wells;
• not requiring the sub-district to prove ownership or control over sufficient legally available replacement water to cover depletions from pumping sub-district wells;
• allowing the sub-district to utilize the water rights subject to the decrees referred to in Case Nos. 06CV64 and 07CW52 as the “recharge decrees” and in approving the quantification of fully consumable water in estimating ground water depletions;
• finding that the sub-district’s proposed use of Closed Basin Project water is not prohibited;
• allowing a 50 acre foot per year lower limit for the determination of injurious depletions and in allowing the replacement of injurious depletions in subsequent years;
• not adopting, rejecting, or referring back the plan of water management to the sub-district (the judge had referred the plan back to the sub-district board of managers once before);
• not affording objectors the opportunity to propose specific terms and conditions to the plan of water management;
• not requiring the sub-district to replace all injurious depletions, including ongoing depletions resulting from past pumping of sub-district wells, until the year 2012;
• approving Appendix 4 (budget and accounting plan) and Appendix 5 (operational timelines) of the plan of water management;
• determining the sub-district may contract with the owners of any non- sub-district wells.
• finding that individual plans of augmentation in Water Division 3 are not presently possible and cannot be completed with any engineering validity;
• finding that the calculation of the Surface Water Credit in Appendix 2 of the plan of water management is reasonable and supported by the record;
• finding that the amended plan of water management’s change in timing for removing land from irrigation to effectuate further recovery of the unconfined aquifer to a sustainable condition is lawful.
