<br />(6) For printout purposes, uncontrolled cumulative local flows <br />(flow below all upstream reservoirs) do not include releases from upstream <br />reservoirs if one acre-foot or more of flood control storage is used, <br />otherwise uncontrolled local flows will include flows from upstream <br />reservoir drainage areas. <br /> <br />(7) In addition to flood control operation, conservation operation <br />may be specified to provide minimum flows at one or more downstream <br />1 ocati ons, for two levels of dependabi 1 ity (des i red and requi red). based <br />on reservoir storage. <br /> <br />(8) A reservoir can operate to meet at-site power requirements or <br />allocatee system energy in kilowatt-hours. <br /> <br />h.
