Shortages increase as follows: <br />The first month that a rule curve is violated a 30S shor- <br />tage is set. the second month - 50S shortage. the third <br />month - 70S. and the fourth month 100S shortage. <br />Releases for water sales were also shorted if the useable <br />power pool went dry. <br /> <br />50 <br /> <br />Power Release for Reservoir Storage Regulation. Additional <br />simulated powerplant releases in excess of required <br />releases. Silt Project releases. and total water sales <br />are projected beginning October 16 to achieve desired <br />winter drawdown and not deplete the usable power pool by <br />April 15. An average power release was computed beginning <br />in the October 16-31 period and adjusted in December. with <br />no power releases made if reservoir storage fell below <br />specified levels. A perfect April 1 - July 31 -forecast- <br />was modeled in February and power release rates adjusted <br />accordingly depending on a high or low forecast. During <br />high runoff years. additional power releases were made in <br />May - July if necessary to prevent a reservoir spill in <br /> <br />excess of powerplant capacity. assuming a <br /> <br />perfect <br /> <br />-forecast. - <br />
