instream flow conditions and the needs of the water users. A sample "call sheet" for District 25 is <br />provided as Attachment 3. <br />Interaction with Division 3 <br />While the District Commissioner is responsible for on-the-ground administration of water rights, <br />his efforts are directed and overseen by the Water Division 3 office. Daily diversion and storage <br />records are compiled by the Commissioner, then provided directly to the Division 3 office for <br />review and incorporation into the State's diversion record database. <br />Interstate Compact Administration <br />Use of water rights within District 25 is not effected by requirements set forth under of the Rio <br />Grande Compact because all streams in the District are tributary to the Closed Basin and do not <br />effect the Rio Grande. <br />Swing ("calling") Rights <br />The daily administration of water rights in District 25 is routinely effected by several calling <br />priorities. These calling priorities (or "swing rights") differ depending on the flow levels of the <br />many different creeks. In general, major calls occur where major decrees come on line. For San <br />Luis Creek and its tributaries, significant swing rights include number S land number 55 priorities <br />(upper San Luis Creek) and the number 9 priority (Kerber Creek). The Commissioner noted that <br />approximately 25 cfs is needed at the Kerber Creek gage to be able to deliver water to the number <br />23, 33, and 36 priorities which are all located within the lower reach of San Luis Creek. <br />Interaction with Water Users <br />As previously described, Commissioner interaction with water users is frequent, and discussions <br />with owners of the larger ditch systems typically occur on a daily basis. These discussions often <br />address creek flow rates and calling water rights. The Commissioner appears to have developed <br />excellent relationships with most water users in the District and discussions are informal, friendly <br />and cooperative. The Commissioners frequently attend water user meetings and discussion <br />groups. <br />Irrigation Techniques in the District <br />The majority of irrigation in District 25 occurs using flood irrigation and flood border techniques. <br />There are also a few sprinkler systems (center pivots) in the District. The efficiency of the flood <br />techniques that are used tend to be fairly low, although to some degree the losses that are <br />experienced serve to raise the water table, thereby providing asub-irrigation supply. <br />Cropping in the District <br />Cropping in District 25 consists of a mix of field crops including alfalfa, pasture hay and small <br />grains. Cropping information is provided by water users in the District on an annual basis and <br />this information is recorded in the State's database. <br />C:Acdss\D25_Mem.doc District 25 Interview July 2, 1999 -Page 8 of 9 <br />
