It has come to my <br />attention that some of the Board members may have a conflict with the Board's meeting date in <br />November due to the National Water Resources Association Annual Conference in Phoenix, Arizona <br />from November 9-12,1999. The Board members may want to consider moving the meeting to either <br />November 3'd or November 17'b. <br /> <br />AGENCY MANAGERS' REPORT <br /> <br />The Agency Managers have not met since the July Board meeting. <br /> <br />PROTECTION OF EXISTING RIGHTS <br /> <br />Colorado River Water Report <br /> <br />During June 1999, storage in the major Upper Basin reservoirs increased by <br />2,234,000 acre-feet and storage in the Lower Basin reservoirs decreased by 155,000 acre-feet.
