<br />Key questions relating to reconciling risks of spill <br />and purposeful spike flows <br /> <br />AOP Issues <br /> <br />'B11~r <br />What is the appropriate triggering mechanism for allowing spike flows to <br /> <br />occur? <br /> <br />How are January and July target levels and end of water year storage affected <br /> <br />by spill avoidance? <br /> <br />Identify the various release pattern alternatives for various inflow scenarios. <br /> <br />T echnicallStatistical <br /> <br />What are the risk levels that correspond to the need to release greater than <br />25,000 cfs? <br />What is the long term frequency of reaching a trigger mechanism at various <br />levels of risk? <br />What is the long term frequency and magnitude of uncontrolled spills? <br />Are the historic forecast error curves still valid? <br />What are the technical issues associated with use of the spillway? <br /> <br />Resource Management Concerns <br /> <br />What are the resource issues associated with making high releases to avoid <br />uncontrolled spills? <br />What are the effects of uncontrolled spring spills? of double spills? <br />What are the power costs associated with spring spills and their avoidance? <br />What are the 1998 impacts of releases greater than 20,000 cfs? 25,000 cfs? <br />What are the various resource values at each month in the winter/spring, and <br />how do operations decisions affect them? <br />
