<br />maf minimum objective release year. Releases will continue to follow this pattern through the <br />winter months. Additional water released over and above the 8.23 maf. as required for storage <br />equalization between Lake Powell and Lake Mead. will likely take place in the ~er months <br />of 2002. <br /> <br />Inflow to Lake Powell has continued to be below average in water year 2002. Unregulated <br />inflow to in October. 2001 was 244.000 acre-feet (45 percent of average), and unregulated inflow <br />in November, 2001 was 330.000 acre-feet (63 percent of average). December. 2001 unregulated <br />inflow was 280.000 acre-feet (65 percent of average). <br /> <br />With forecasted 2002 April through July inflow to Lake Powell at only 67 percent of average, it <br />is looking like water year 2002 may be the third consecutive year with below average inflow. <br />Unregulated inflow in water years 2000 and 2001 was 62 percent and 59 percent of average. <br />respectively. <br /> <br />The current elevation of Lake Powell is 3,655.5 feet (44.5 feet from full pool). Current storage is <br />approximately 17.9 maf (73 percent of capacity). Under the current forecasted inflow, Lake <br />Powell would reach a peak elevation of about 3,660 feet in late June or early July. The actual <br />peak elevation for Lake Powell in 2002 will ultimately depend upon observed runoff this spring. <br />Observed inflow often deviates from early season inflow forecasts. <br /> <br />;;. <br />
