<br />ALTERNATIVES (Continued <br />from page 1) <br /> <br />Steady Flow <br />Alternatives <br /> <br />The Steady Flow Alternatives <br />have been designed to <br />substantially reduce fluctuations <br />resulting from peaking power <br />generation and to protect <br />downstream resources. Releases <br />may be adjusted throughout the ~ <br />year in order to avoid spills and U <br />.5 <br />balance storage between Lake <br />Powell and Lake Mead. <br /> <br />Year-Round Steady Flow <br />Alternative - This alternative was <br />developed to release water from <br />Glen Canyon Dam at a steady <br />year-round rate, eliminating <br />daily and monthly river <br />fluctuations except as necessary <br />for monthly forecasted <br />adjustments. The figure <br />compares releases under the <br />Year-Round Steady Flow <br />Alternative (solid black line) with <br />actual releases in water year 1989. <br /> <br />Seasonally Adjusted Steady <br />Flow Alternative - This <br />alternative features a flow regime <br />that addresses the varying <br />seasonal needs of downstream <br />biological resources and includes <br />water releases at a constant rate <br />within each month. Although <br />the cooperating agencies approve <br />of the concept of this alternative, <br />specific operational parameters <br />are still being reviewed. The <br />figure compares seasonally <br />adjusted steady flows (solid black <br />line) with water year 1989 <br />operations. <br /> <br />32,000 <br /> <br />28,000 <br /> <br />24,000 <br /> <br />20,000 <br /> <br />18,000 <br /> <br />~ <br />o <br />iL <br /> <br />12,000 <br /> <br />8,000 <br /> <br />4,000 <br /> <br />32,000 <br /> <br />28,000 <br /> <br />24,000 <br /> <br />20,000 <br /> <br />ff! <br />o <br />.5 <br />~ <br />o <br />r;: <br /> <br />16,000 <br /> <br />12,000 <br /> <br />8,000 <br /> <br />4,000 <br /> <br />Year-Round Steady Flow Alternative <br />(1989 Conditions - 8.2 mat annual release) <br /> <br />_ AcIuIIl_ c.IIy FI..ge <br />- StMdyFlow__ <br /> <br />o <br /> <br /> <br />OCT NOV DEe JAN FEB MAR APR MAY JUN JUL AUG SEP <br />Water Year 1989 <br /> <br />Seasonally-Adjusted Steady Flow Alternative <br />(t 989 Conditions - 8.2 mal annual release) <br /> <br />_ AcluaIl9B9 Dally Range <br />- Steady Flow AIlematIve <br /> <br />o <br /> <br /> <br />OCT NOV Dee JAN FEB MAR APR MAY JUN JUL AUG SEP <br />Water Year 1989 <br /> <br />5 <br />
