Gauge Information
Gauge Description:
Combined flows of Green and Colorado. Average annual peak is approximately 45,000 cfs. Highest recorded flow was 110,500 cfs on 27 May 1984, but it's been higher.
Lake Powell elevation and inflow.
Colorado River flows have been below average since the year 2000, leading to lower lake levels. In the winter of 2005 (before the spring run-off) the lake reached its lowest level since filling, an elevation of 3,550 feet (1,080 m) above sea level, which was approximately 150 feet (46 m) below full pool (elevation 3700'). Since 2005 the lake level has risen 78 feet (24 m), to a high elevation of 3,628 feet (1,106 m) above sea level in spring/early summer 2008. It is estimated this upcoming spring runoff may produce a peak elevation of 3638' during mid-summer 2008.
