between late April and mid-May. These conditions commonly require Commissioners to identify <br />futile call situations and to administer water deliveries accordingly. <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 and curtailment percentages. <br />Interstate Compact Administration <br />Use of water rights within District 22 is significantly effected by requirements set forth under the <br />Rio Grande Compact. The Compact defines specific water delivery requirements that must be <br />made to New Mexico. These delivery requirements are a function of flows measured at several <br />"Index Gages" located on the Rio Grande River and Conejos River in Colorado. <br />District Commissioners work closely with Division 3 staff to obtain delivery obligations to the <br />Rio Grande at the downstream end of the District. These delivery requirements are an obligation <br />under the Compact, and use of all other water rights are administered to meet this obligation. <br />Day-to-day administration of the Compact delivery requirements occurs by way of establishing a <br />"curtailment" percentage of flows measured at the District's three Index Gages (Conejos at <br />Magote, Rio San Antonio at Ortiz, and Rio Los Pinos at Ortiz). This curtailment percentage is <br />determined by Division 3 staff every ten days during the irrigation season and communicated to <br />District Commissioners. See the RGDSS memorandum documenting discussions with Division 3 <br />for more information about Compact administration. <br />Swing ("calling") Rights <br />The daily administration of water rights in District 22 is routinely effected by several calling <br />priorities. These calling priorities (or "swing rights") differ depending on the flow levels of the <br />Conejos ,Rio San Antonio and Rio Los Pinos. In general, major calls occur where major decrees <br />come on line. For the Conejos River and its tributaries, significant swing rights include the <br />Santiago Ditch (priority number 16 for 42 cfs). As soon as the Santiago Ditch right (priority <br />number 16) goes out, no additional water is delivered down the North Branch below the Core. <br />The Magote Ditch (priority number 115 for 342 cfs) and the Antonito Ditch (priority number 113 <br />for 139 cfs) are additional significant swing ditches. <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 River flow rates, the Compact curtailment status, calling water rights. The <br />Commissioners appear to have developed excellent relationships with most water users on the <br />River and discussions are informal, friendly and cooperative. The Commissioners frequently <br />attend water user meetings and discussion groups. <br />C:Acdss\D22_Mem.doc District 22 Interview July 2, 1999 -Page 7 of 9 <br />
