In dry yeazs, the call is assumed to run from July 1 <br />to October 1. <br />MCC ensures that when the Mount Gunnison Pipeline was out of priority, the river is "left whole" <br />via an arrangement for flow releases as described below. MCC will provide future call status and <br />total water diversions in subsequent Annual Hydrology Reports. <br />When there is no water right call on the North Fork, MCC is able to divert using the Mount <br />Gunnison Pipeline in priority. When there has been a call, however, MCC has offset its out-of- <br />priority diversions (via the Mount Gunnison Pipeline) by augmenting the North Fork flows through <br />releases from the East Beckwith No. 1 Reservoir (Lost Lake Slough), MCC's upstream storage <br />right. The State Engineer's Office (SEO) has allowed the Mount Gunnison Pipeline to continue to <br />divert out of priority and has required the appropriate releases from East Beckwith No. 1 Reservoir <br />to prevent injury to other vested water rights. <br />Table 46 provides MCC's diversions, return flows and depletions to the North Fork for three <br />different time periods. (The significance of these time periods is described in the following Section, <br />Mine Water System). <br />~~ <br />2.05-215 Revised Jun /995 PR06; Revised Nov. 1998 TR80; 1/98 PR08; Rev.
