<br />00245!1 <br /> <br />. <br /> <br />. <br /> <br />') <br /> <br />Glen Canyon Dam Adaptive Manauement Program <br /> <br />Mr. Harris and I attended the recent meeting of the Glen Canyon Dam Adaptive Management Work <br />Group (AMWG) on April 25-26, 2002, in Phoenix, Arizona. At the meeting, there were reports associated <br />with the following: (I) the Grand Canyon Monitoring and Research Center's (GCMRC) preparation of the <br />biennial report to Congress; (2) development of potential non-native fish controls in the Little Colorado <br />River and Bright Angel Creek; (3) Colorado River Basin hydrology; (4) proposed experimental flow <br />releases in Water Year 2003; (5) proposed FY -2004 budget; and (6) continued review and discussion of <br />proposed information needs and management objectives associated with the overall Glen Canyon Dam <br />adaptive management program. <br /> <br />There was substantial discussion associated with the proposed experimental flow releases for Water <br />Year 2003. These science flows are intended to mobilize existing sediment resources in the main river <br />channel and deposit them on the banks and beaches. The issue is the timing of the proposed science flows. <br />Generally, the scientists in the GCMRC propose to lower releases from Glen Canyon Dam in the late- <br />Summer and early-Fall in order to conserve sediment resources input into the system from localized storm <br />events, and then conduct a 45,000 cubic-feet.per-second "spike-flow" release in December or January to <br />move the sediment up onto the beaches. The proposed hydrologic scenarios may affect the generation of <br />electrical energy for Colorado River Storage Project (CRSP) customers. <br /> <br />Finally, related to the proposed science flows, I can report that there are additional discussions <br />occurring among participants in the AMWG, Basin States' representative, Western Area Power <br />Administration, and Reclamation regarding the current Colorado River Basin hydrologic and reservoir <br />conditions and potential Glen Canyon Dam release regimes in the context of the Annual Operating Plan <br />and Section 602(a) of the Colorado River Basin Project Act. <br /> <br />, <br />~ . \ <br /> <br />WATER QUALITY <br /> <br />Colorado River Basin Salinity Control Forum <br /> <br />The seven Basin States established the Colorado River Basin Salinity Control Forum in 1973, for <br />interstate cooperation and to provide the states with the information necessary to comply with Section <br />303(a) and (b) of the Clean Water Act. The Forum is composed of three representatives from each of the <br />Basin States, appointed by the governors of the respective states. <br /> <br />Historically, one of California's representative on the Forum has been the Executive Director of <br />the State Water Resources Control Board (SWRCB). With the retirement of Mr. Walter Pettit, the State <br />of California has initiated the process to appoint Ms. Celeste CantU, the new Executive Director of the <br />SWRCB. Hopefully, Ms. CantU will be able to attend the Forum's next meeting scheduled for June 5, <br />2002, in Silverthorne, Colorado. <br /> <br />7 <br /> <br />~. <br />
