<li>All uncontracted storage available in Prineville Reservoir on the annual day of allocation, up to a maximum of 13,000 acre feet, is held until the end of the active irrigation season² and thereafter released at a daily average rate of 50¹ cfs as measured at PRVO.</li>
<li>All City of Prineville mitigation storage available in Prineville Reservoir on the annual day of allocation and not required for another mitigation use³, up to a maximum of 5,100 acre feet, is held until December 1 and thereafter released in lieu of uncontracted storage to maintain the daily average flow of 50 cfs as measured at PRVO.</li>
<li>The combined total of available uncontracted storage (up to 13,000 acre-feet) and available City of Prineville mitigation storage described herein is insufficient to maintain the daily average flow of 50 cfs as measured at PRVO until the beginning of the next irrigation season.</li>
</ol>
<p> Water that is temporarily leased instream from OID patrons may be used to support the flow of 50 cfs (±5 cfs), except during the period from December 1 through January 31.</p>
<p>During the active irrigation season, the DBHCP will not obligate OID or NUID to allow bypass of live flow or release of contracted storage by Reclamation on OID’s or NUID’s behalf to maintain specific instream flows at PRVO Gage or CAPO Gage. However, OID will not divert stored water at the Crooked River Diversion until the water has been released from Prineville Reservoir and adequate time has elapsed for the water to reach the diversion. In addition, as the operator of Bowman Dam, OID will respond to calls for Prineville Reservoir stored water from other contract holders and begin releasing the requested water within 24 hours.</p>

<ol>
<li>The OWRD’s or Bureau of Reclamation’s predicted March month end contents of Prineville Reservoir are less than or equal to the 50 percent exceedance level of the contents at March 31 based on all data from the prior 30 years, and</li>

<ol>
<li>The conditions necessary for a Dry Year Declaration do not apply, or</li>
<li>When OWRD fails to make any written Dry Year Declaration.</li>

</ol>
<p>OWRD shall maintain discretion to apply and interpret the Dry Year Declaration metric if there is an extenuating circumstance(s) with respect to predicted March month end contents of Prineville Reservoir or its outflows 30 days prior to a Dry or Non Dry Year Declaration so as to target a Dry Year recurrence interval of 3 out of 10 years over a 30 year period. Further, upon request by NUID and the DRC, OWRD may revise the metric, including revisions to the timing for finalizing a Dry Year or Non-Dry Year Declaration, if it is expected that the recurrence interval of a Dry Year Declaration over a 30 year period will change from 3 out of 10 years.<br /> <br /><strong>The Crooked River is also affected by CR-4, 5, and 7, conservation measures that are not dependent on stream gauging.
