This notification confirms that the release volume from Glen Canyon Dam for March 2015 will be 650,000 acre-feet. Hourly and daily average releases from Glen Canyon Dam for March 2015 will be scheduled through Western Area Power Administration to be consistent with the Glen Canyon Dam Operating Criteria (Federal Register, Volume 62, No. 41, March 3, 1997) and to also achieve, as nearly as is practicable, this monthly volume. Hourly releases during March 2015 are anticipated to fluctuate between approximately 7,250 cfs in the nighttime and approximately 13,250 cfs in the daytime.
We anticipate the release volume for April 2015 will be 600,000 acre-feet with fluctuations between approximately 7,500 cfs and 13,500 cfs. The anticipated release volume for May 2015 is 700,000 acre-feet with fluctuations between approximately 8,500 cfs and 14,500 cfs. This will be confirmed in a subsequent notification toward the end of March.
