SUMMARY The 2008 Watermaster Report was posted to the Office of the State Engineer (OSE) website in mid-March. We held a public forum on Water Use on March 31, 2009 that was very well attended. There were many accomplishments in 2009. The OSE dedicated much time and resources to the following activities which showed our commitment to the Gallinas River basin: the continuing adjudication process, involvement in the City of Las Vegas (COLV) Remand negotiations, signing of the remaining ditch metering agreements, installing flow measuring devices, building a State-funded weir at the Storrie Project point of diversion with the reconstruction of the attached river gate and the monitoring of flows and diversions (see Attachment A-6A & A-6B). The snow melt did not increase the Gallinas River stream flows during the 2009 Spring very much due to a less than average snowpack (see Attachments A-15 & A-16). The 2009 rains did not generate much storm run-off upstream of the USGS Montezuma gage (see Attachments A-10 & A-11) keeping the Gallinas River stream flows (at the USGS Montezuma gage) low in the later months of the irrigation season. The slightly below average rains did provide effective precipitation for agriculture and COLV residents’ outdoor uses (see Attachments A-8 & A-9). The Rio Gallinas Acequia Association (RGAA) requested that the irrigation season start in mid-March to take advantage of the snow melt runoff in the early spring. The RGAA also requested that the OSE not implement a rotation during low flows in the irrigation season as it might conflict with their negotiations on the “river-sharing” agreement with the COLV in the ongoing adjudication Remand negotiations. The COLV and the RGAA acequias implemented a “river-sharing” agreement during the year, which set stream flow and City storage triggers and when the City would come on/off the river.
INTRODUCTION
The State Engineer has the broad authority to administer water rights and it is specifically provided for the Gallinas River by NMSA 1978, Section 72-3-1 (1919) and in Section 72-3-2 (1907). Administration in the Gallinas River was established by declaration of the Gallinas River Water Sub-district of the Pecos River Stream System filed as New Mexico Administrative Code (NMAC) Order 19.26.11, which became effective August 29, 2003. The Gallinas River basin is located in north-central New Mexico (see Attachment A-1). The Gallinas River headwaters are located on the eastern slopes of the Sangre de Cristo Mountains, at an elevation of approximately 11,660 feet. From its headwaters, the river traverses southeasterly approximately 85 miles and enters the Pecos River six miles upstream of the Village of Colonias. The COLV is located in the north-central part of the drainage basin.

The Gallinas River has no major perennial tributaries. The larger tributaries are Porvenir Canyon, Trout Springs, Cañon Bonito, Pecos Arroyo, and Aguilar Creek. The drainage basin of the Gallinas River and its tributaries contains approximately 610 square miles. The OSE Gallinas River Water Master has the responsibility of managing the Gallinas River. For management purposes, the Gallinas River is divided into three separate areas. The following diverters arecurrently recognized in the three separate areas: Upper Gallinas Area From the headwaters to the USGS Montezuma gage
Middle Gallinas Area From USGS Montezuma gage to the USGS Lourdes gage
Lower Gallinas Area From the USGS Lourdes gage to the Pecos River

There is an ongoing adjudication process in the Gallinas River basin; therefore, this listing of diversions is subject to changes as the court recognizes water rights.
MEETINGS
The OSE held a public meeting at the Luna Community College on March 31, 2009, a Forum on Water Use that was very well attended. The Memorial Middle School Ag Program, the San Miguel County Ag Extension Service, and the Las Vegas Wildlife Refuge made presentations at the Forum. Talks continued between the OSE and the RGAA on the language in the ditch metering agreement with the assistance of OSE Community Liaison Richard Trujillo. After the RGAA and OSE agreed to the language (see Attachments A-2 & A-3), the remaining major acequias signed off on their ditch metering agreements. The OSE held a meeting on April 23, 2009 with some acequias to determine the alternating groups and the intervals on/off the river for the rotation among the Acequias during low flows for this irrigation season (see Attachments A-4 & A-5). The RGAA
Page 3 of 7
later requested that the OSE not implement a rotation so that it would not conflict with their negotiations on the river-sharing agreement with the COLV. The RGAA and the COLV decided on a “river-sharing” agreement in 2009 amongst themselves to resolve the remand litigation which would define the priority of the City’s water rights. The intent was that the agreement would be tested for three years beginning in 2009 to fine-tune the details. It was anticipated that after each irrigation season, changes could be made to the agreement conditions for the next irrigation season. The COLV and the RGAA followed the diversion schedule defined in the agreement in 2009. At the request of Storrie Project WUA, the Acequias and the OSE, the NRCS prepared a design to modify the Storrie diversion structure that would allow the high flows to be diverted to Storrie Lake and the low flows to continue downstream to the senior acequias. The OSE agreed to fund the project and construction began in November 2009. (See Attachment A-6A).
HYDROLOGY
Installation and Measurement of Flow Measuring Devices The ditch diverters were consulted on the size of the flume and its placement location at each ditch or canal. OSE staff: Vince Chavez and Brian Gallegos coordinated with Sutron, the contractor, and the acequias, on the installation of the flumes and the bubbler. The following locations had flow measuring devices installed in 2009 (see Attachment A-6B): DIVERTER MEASURING DEVICE MONTH 2009

The United World College and Cleo Fresquez installed pipe meters in 2009 to measure their river pump diversions. The Trout Springs Ranch, Archie Allemand and Marc May should be installing pipe meters before the next irrigation season. The weir construction at the Storrie Project WUA point of diversion and the reconstruction of the attached river gate began in November 2009. This project included a flow measurement device on the Gallinas River immediately downstream of the above-mentioned river gate. Staff gages will be or have been installed in the following locations: Placita Arriba Ditch Upper Maestes Ditch El Porvenir Ditch Max Nordhaus Ditch (pending staff gage installation) Agapito Vigil Ditch (pending ditch curve) Pappen Ditch Gallinas River below Pappen Ditch Point of Diversion (to measure stream flows) Pecos Arroyo (to measure stream flows) Ancon del Gato (pending ditch curve)
In 2009, the OSE Water Master was not assisted by Acequia Majordomos nor Highlands University students in monitoring diversions and flows in the Gallinas River. Ditch curves were not developed for some of the staff gauges that had to be replaced or moved to a better location. Due to many reasons, the Gallinas River flows and diversions were not monitored as often as in the two prior years. The monitoring of flows and diversions at least once a week began in late May, therefore there was no data collected in March, April and part of May (see Attachment A-7). Precipitation, Stream flows and Weather. The 2009 precipitation for the Las Vegas area was 12.24 inches (see Attachment A-8). For the irrigation season, there were 11.40 inches of precipitation and 10.10 inches of effective precipitation (see Attachment A-9). For the irrigation season from April 1 – October 31, 2009, the Gallinas River flows measured at the USGS Montezuma gage totaled 6,818.99 acre-feet (see Attachment A-10). The spring runoff provided average daily flows above 15 cfs, measured at the USGS Montezuma gage, from April 14 – May 30 and rains provided them for a week in June, a few days in July, and two weeks in September. The average daily flows were at 15 cfs or below for 144 days of the 214 days (⅔ of the time) of the irrigation season (see Attachment A-11). The rains did little to increase the Gallinas River stream flows (as measured at the USGS Montezuma gage) during the monsoon months of the irrigation season, but they did help reduce the demand on the river in June, July and September. The average daily flows were above 50 cfs only twice this year: once in July and once in October.

For 2009 the last freeze of winter occurred on March 27, 2009 when temperatures rose above 32º F and the first freeze of winter occurred on December 2, 2009 when the temperatures fell below 32º F. Observations from 2009 Diversions and Enforcement Activities. The COLV operated in accordance with a “river-sharing” agreement which was signed by the City and the acequia members of the RGAA. The agreement defined when the COLV would be on/off the river, stream flow and City storage triggers, and its diversion rate in 2009. The COLV was off the river for two weeks in June and two weeks in July through the first part of August for a total of 34 days (see Attachment A-12). While off the river the City used their water storage until they hit the storage trigger that put them back on the river. The COLV supplemented their surface water with water from the Taylor Well Field to help them keep up with their demand. The diversions and flows of the Gallinas River for four separate dates in 2009: August 13, August 21, August 28 and October 8 were placed on an attached table (see Attachment A-13). The table shows that the diversions and flows in the Middle Gallinas River section (downstream of the Storrie Project POD and upstream of the COLV WWTP) were approximately 350%, 450%, 350% and 150% of the flows estimated at the Gallinas River gate at the Storrie Project POD, indicating that return flows and/or natural gains provide a substantial water supply in the Middle Gallinas River Area. The diversions and flows of the Gallinas River on the above-mentioned dates show that without an agreed rotation among the acequias, that either they were all diverting, with insufficient flow going to each ditch; or that one or two acequias were taking all the stream flow. Without a formal rotation what normally happens is that, acequias divert water only when the upstream acequias are satisfied, or they have to request the upstream acequias to bypass flows. Enforcement issues were limited to two incidents. In April a parciante was cleaning the river of silt along their property. The investigation revealed that the silt removal was minor and did not appear to modify the flooding patterns. In September a parciante used a river pump to irrigate his land from an illegal/unpermitted Point of Diversion. In both instances, they ceased the activity and no further enforcement actions were pursued.

PENDING MATTERS AND OUTLOOK FOR 2010 The COLV and the acequias in the RGAA will meet early in 2010 to discuss the problems that occurred during the implementation of their 2009 river-sharing agreement and come up with a 2010 river-sharing agreement. In 2010 the OSE will have more accurate measurements of diversions and flows thanks to the installation of the flumes with their corresponding data recorders in 2009. Approximately 95 % of the flows in the river system will be measured continuously (data recorders) and another 3% periodically (staff gages). The Water Master is responsible for maintaining the flumes clear of debris for their proper operation. Majordomos should report any debris or obstructions that they notice in the flow measuring devices. The weir downstream of the river gate at the Storrie Project WUA Point of Diversion and the pipe meter on the San Augustin Community Ditch should be installed prior to the 2010 irrigation season. The accuracy of measuring diversions using staff gauges will depend on the availability of the Water Master to monitor diversions and flows in 2010, the availability of summer help (college students) and the collaboration by majordomos in communicating with the OSE Watermaster when they open and/or close their headgates. OSE staff need to perform additional flow measurements in the acequias to develop or calibrate the ditch curves to continue to use the staff gauges to measure flows and diversions. A rotation is strongly suggested in 2010 for the period of low flows during the irrigation season. As of March 25, 2010, the SNOTEL report showed 59.0 inches of snow and 16.4 inches of snow water equivalent at their Wesner Springs site which is above average for this time of year. The snow accumulation is slightly above average due to late winter storms which should provide much better snow melt runoff in the Spring of 2010 than last year, in 2009 (see Attachments A-14, A-15 & A-16). The installation in 2009 of several flow measuring devices at key stream locations and at diversion points on the Gallinas River shall help improve the management of Gallinas River basin. Talks and cooperation among the diverters should continue toward common solutions to the challenges that arise from the periodic droughts that occur in this area. For the common good of the region, the diverters should make the effort, to minimize waste and limit their diversions for beneficial use and of their water rights per annum.
