instream flow conditions and the needs of the water users. A sample "call sheet" for District 20 is <br />provided as Attachment 6. <br />While the majority of diversion records reflect actual observations by the Commissioners, <br />diversions through other structures may be reported by the ditch owners ("user supplied" <br />information). Records that are supplied by ditch owners typically occur on the smaller, junior <br />water rights that are less important from an administrative perspective. <br />Interaction with Division 3 <br />While the District Commissioners are responsible for on-the-ground administration of water <br />rights, their efforts are directed and overseen by the Water Division 3 office. Daily diversion and <br />storage records are compiled by the Commissioners, then provided directly to the Division 3 <br />office for review and incorporation into the State's diversion record database. In addition, <br />Division 3 plays an integral role in District administration in that it provides information <br />regarding Rio Grande Compact delivery obligations. Additional information regarding the <br />Compact administration can be found in memorandum documenting the Division 3 interview. <br />Interstate Compact Administration <br />Use of water rights within District 20 is significantly effected by delivery requirements set forth <br />under the Rio Grande Compact. The Compact defines specific water delivery requirements that <br />must be made to New Mexico as measured at the Rio Grande at Lobatos Gage. These delivery <br />requirements are a function of flows measured at several "Index Gages" located on the Rio <br />Grande and Conejos River in Colorado. <br />District Commissioners work closely with Division 3 staff to obtain delivery obligations from the <br />Rio Grande. These delivery requirements are in effect considered to be a permanent call, and use <br />of all other water rights are administered to meet this obligation. Day-to-day administration of <br />the Compact delivery requirements occurs by way of establishing a "curtailment" percentage of <br />flows measured at the Del Norte Gage after several adjustments are considered. This curtailment <br />percentage is determined and monitored by Division 3 staff every ten days during the irrigation <br />season and communicated to District Commissioners for adjustment if necessary. Additional <br />information regarding the Compact administration can be found in the memorandum <br />documenting the Division 3 interview. <br />Swing ("calling") Rights <br />The daily administration of water rights in District 20 is routinely effected by several calling <br />priorities. These calling priorities (or "swing rights") differ depending on the flow levels of the <br />Rio Grande. In general, major calls occur where major decrees come on line, for example the <br />Rio Grande Canal's 318.4 cfs right and the Empire Canal's 312.3 cfs right. <br />Interaction with Water Users <br />As previously described, Commissioner interaction with water users is frequent, and discussions <br />with superintendents of the larger ditch systems typically occur on a daily basis. These <br />discussions often address River flow rates, the Compact curtailment status, calling water rights. <br />The Commissioners appear to have developed excellent relationships with most water users on <br />the River and discussions are informal, friendly and cooperative. The Commissioners frequently <br />attend water user meetings and discussion groups. <br />C:Acdss\D20_Mem.doc District 20 Interview July 2, 1999 -Page 7 of 9 <br />
