<br />The following represent desirable outcomes. Some goals are more attainable than others. <br />They are intended as guidance for water suppliers in their operating decisions. All goals <br />are subject to the principles contained on page 4. The details of the goals are contained <br />on the page referenced. <br /> <br />1. <br /> <br />,Oo;tl <br />Spinney Mountain Reservoir --When inflow is low Inake <br />storage releases to maintain 111inimum outflow. <br /> <br /> <br /> <br />2. <br /> <br />Eleven Mile Reservoir - When inflow is low I1lake <br />stora e releases to maintain nUniITIUln outflow. <br />Cheeslnan Reservoir - When inflow is low Inake storage <br />releases to ll1aintain Ininilnllnl outflow. <br />Operate Spinney Mountain Reservoir for outflows in <br />o tiU1U111 ran e of 50 to 150 cfs. <br />Operate Eleven Mile Reservoir for outflows in optinlUITI <br />ran :rc of 50 LO 100 cfs. <br />Operate CheeSJ11an Reservoir for outflows in optimum <br />range of 50 to 150 cfs (August-March) and 100 to 225 cfs <br />(A ril-Jul ). <br />Spinney Mountain Reservoir - Operate to lninimize <br />S iIlin . <br />Eleven Mile Reservoir - When reservoir is spilling, <br />operate to discharge within optilTIUlTI range of 50-600 F <br />(June - September) with a Inaxilnum of 650 F and <br />fluctuations no more than 100F er da . <br />Cheestnan Reservoir -When reservoir is spilling~ operate <br />to discharge within optimUITI range of 50-600 F (June- <br />Septenlber) with a 111axi'TIUI11 of 650 F and fluctuations no <br />more than looF er day. <br />Discharges froIl1 the Roberts Tunnel into the North Fork <br />will consider the needs of \vhitewater recreation and fish <br />habitat.
