From the Valley Courier (Rob Phillips):
This is the 15th article in the series from the Rio Grande Basin Roundtable, regarding the formation and implementation of the Basin Water Plan. The primary goal of Subdistrict No. 1 is to remedy injurious depletions to senior surface water rights and keep those water users whole.
The Subdistrict has several methods to do this. First, the subdistrict has purchased and leased water, both native to the Rio Grande Basin and water imported from the West slope. This water is stored and released as directed by the Division Engineer to replace stream depletion replacement within stream reaches of the Rio Grande as they occur. By doing this, the river itself is kept whole with wet water replacing the depletions in time, location and amount.
The subdistrict can also use what are known as forbearance agreements. Colorado law allows the subdistrict to remedy injurious depletions by a means other than supplying wet water. The subdistrict can do this by agreeing with a ditch that, rather than replace depletions with water, the subdistrict will pay the ditch some amount of money for each acre-foot of water the ditch does not receive because of depletions caused by subdistrict wells.
Each day the Division Engineer tells the subdistrict which ditch is “on the bubble,” that is the most junior ditch that is in priority that day and that is not receiving its full water supply under that priority. The subdistrict then looks at the Annual Replacement Plan to see the depletions caused by subdistrict wells on that day, water that the ditch on the bubble would have received. The subdistrict keeps track of the total amount of water due to each ditch that has a forbearance agreement and pays them at the end of the year. The ditch can then do what it wants with the money, for example upgrading the ditch or simply dividing it up among the ditch users. Forbearance agreements allow ditches and water users to remain whole, while not locking up scarce water resources. So far, the subdistrict and the forbearing ditches are very happy with this arrangement and look forward to continuing working together to reach the best solution for everyone. How the subdistrict is working towards aquifer sustainability
Throughout the recent drought, the aquifer has been shrinking as producers pump more water than is recharged back to the aquifer. The other primary goal of Subdistrict No. 1 is to recover and sustain the Unconfined Aquifer below the subdistrict to the level that existed in the early 1980s. The primary way the subdistrict plans to do this is by reducing the amount of irrigated acres within the subdistrict, which will reduce the amount of pumping from the aquifer. This concept is built into the Subdistrict’s Plan and requires 20,000 acres be retired by the fifth year from judicial approval of the plan, 30,000 acres less by the end of the seventh year, and up to 40,000 acres less by the end of the tenth year all from a base year of 2000.
One tool the subdistrict has to meet these goals is financial incentives and participation in the federal Conservation Reserve Enhancement Program (CREP) to retire up to 40,000 irrigated acres. Currently, 1,970 acres were enrolled in the program in 2013 while another 1,370 acres are currently proposed in 2014. However it is not just CREP acres that count towards the 40,000-acre goal, any program or change that retires acres reduces pumping and assists in achieving and maintaining sustainability . But remember, the subdistrict can only provide incentives, it does not have the power to require wells stop pumping.
The producers of the closed basin area within the San Luis Valley stepped forward when no one else did and created a subdistrict and imposed fees on themselves to replace their wells’ depletions and work to recover and sustain the unconfined aquifer. They did this not because rules or regulations were in place requiring this action, but because they believed these things had to be done.
The process has never been easy and the debate about the best way to achieve the subdistrict’s goals continues. But the subdistrict, led by its board of managers, has continuously worked towards those goals and they remain the leaders in the Valley for replacing depletions and working towards sustainability . Currently, other proposed subdistricts within different hydrological areas of the San Luis Valley are going through the same processes in an attempt to have their plan up and running before the state engineer’s ground water rules are approved within the Rio Grande Basin.
These forming subdistricts have watched and learned from Subdistrict No. 1’s struggles and accomplishments . Those other subdistricts will provide the same protection to their wells, a locally based and operated group that provides an alternative to state administration of ground water withdrawals in Division 3 while protecting senior surface water rights and providing for a long-term , sustainable ground water system.

Meanwhile Sub-district No. 2 is gearing up for operations according to this report from Lauren Krizansky writing for the Valley Courier:
Well owners residing in the Valley’s second sub-district are ready to push forward with a petition after months of voluntary work.
Rio Grande Water Conservation District (RGWCD) Program Manager Cleave Simpson updated the Alamosa County Commissioners (ACC) Wednesday morning on the latest happenings regarding the creation of the next sub-district , which sits in both Alamosa and Rio Grande Counties.
Sub-district No. 2, also known as the Rio Grande Alluvial Sub-district , is comprised entirely of unconfined wells, and is taking on a different form than Sub-District No. 1, he said. The zone is much smaller, only 300 wells compared to 1,000, participation is voluntary and there is no “sustainability requirement” because the wells do not tap into the confined aquifer.
“We are not drawing a boundary,” Simpson said. “We will go to each individual landowner… There are not the same benchmarks to meet.”
Out of the second sub-district’s 300 wells, 152 average more than 10 acre-feet a year, making them subject to the state’s demand to either join a sub-district or to develop an augmentation plan. There are 10 non-private wells in the mix and 60 private well owners.
“It will be a patchwork of parcels,” Simpson said.
Out of those well owners, he said between 12 and 15 have regularly participated in the workgroups over the past few months, and they represent more or less half the wells in the second subdistrict .
In addition, the City of Monte Vista, the Town of Del Norte, Homelake, Colorado Parks and Wildlife and two school districts are in the zone, but will not join the second sub-district because government entities cannot legally be assessed.
They will be held, however, to the same standards, he said, and have the option to contract with Sub-district No. 2, which would include them in its Annual Replacement Plan.
Although assessment methods and fees to replace depletions are still to be determined, he said Subdistrict No. 2 is ready to petition for legitimacy.
“They are ready to go to the public,” Simpson said. “They are ready to start these discussions.”
It depends on where the state is with its pending water rules and regulations in coming months, he said, but the second sub-district hopes to submit its petition to the district court in January 2015.
“The (water) model and rules and regulations are not final ,” Simpson said. “That could cause a delay.”
Once Sub-district No. 2 is established, he said a board of managers (BOM) will be appointed via a court-approved process.
If there is no opposition to the to the second subdistrict’s formation, he said the BOM’s first task will be to draft a management plan, and, if it is also goes unchallenged , fees assessments will begin in late 2015 with collection notices delivered to Sub-district No. 2 participants in conjunction with their January 2016 county issued tax documents.
Due to its uniqueness, he said the second sub-district has options when it comes to mitigating its groundwater depletions.
“There could be some reduction in irrigated agriculture,” Simpson said, “but we might see changes in technologies, crops requiring less consumption and increases in (water) efficiency.”
He added the value of the zone’s water could also increase, but that is also to be determined.
Sub-district No. 1 has resulted in increased values, in some cases almost double, and is drawing interest from buyers from outside of the Valley. The Rio Grande Alluvial Sub-district is the second out of six identified in the Valley to come to fruition under the watch of the RGWCD. Alamosa County will eventually have three within its borders. In addition to Subdistricts No. 1 and No. 2, the fourth sub-district will also fall within its jurisdiction, but it is still in an infant stage.
“It’s good to see the well owners come together,” said Alamosa County Chair Michael Yohn. “Everyone has to be accountable for their water use.”
