At the beginning of the runoff season <br />the basin wide snowpack was about 146 percent of average. <br /> <br />Unregulated inflow into Lake Powell was 20,058 MCM (16.261 MAF) in water year 1997, <br />approximately 139% of average. This inflow resulted in a gain of approximately 1,433 MCM <br />(1.162 MAP) of storage in Lake Powell. Approximately 741 MCM (.600 MAF) of storage was <br />gained in upstream reservoirs, approximately 2,706 MCM (2.193 MAF) was gained in Lower <br />Basin reservoirs, and the total Colorado storage system gain approximately 4,880 MCM (3.955 <br />MAP) during water year 1997. It is estimated that with average inflow during 1998, the system <br />will remain relatively full. During 1997, all deliveries of water to meet obligations pursuant to <br />"The Law of the River" were maintained. <br /> <br />Tables I (a) and I(b) list the expected October I, 1997 reservoir vacant space, live storage, water <br />elevation, percent of capacity, change in storage, and change in water elevation during water <br />year 1997. <br /> <br />3 <br />
