The plan, which will guide reservoir operations between November 1 and April 2018, calls for DWR to maintain lower-than-average lake level's during the winter months to provide space for inflows and manage releases from the substantialily reconstructed main spillway. "This plan puts public safety first, while also meeting our water supply and environmental obligations as we repair and rebuild the Lake Oroville spillways," said DWR Director grant Davis, "We will operate Lake Oroville conservatively until construction on both spillways is complete in late 2018, early 20119."' The, plan calls for DWR to lower the lake level to an elevation of 700 feet by November 1, compared to the average 780 feet elevation maintained on that date in prior years. The lower level will provide more than 2.2 million acre-feet of flood reserve storage to accommodate inflows during the rainy season. The lower lake level, combined with operational contingencies, should allow DWR to keep releases from the mostly reconstructed main spillway at 100,01010 cubic-feet per second (cfs) or less over the winter and ensure lake levels 1 ^. • .. � � .� s • r - r � • .� � � OM1 ""` � �, r � •1 X11 — _ * � .. .. �. - � s w ar W � - r � � ,� � ,w � � ,.,� ,.�� r i � "^• � � • r� -i •�- , � , .,, , / i/ /� � ( i/J „// // / i� j � hili / 1 // / I / / //l � / / / /i/ I // / l/ � i / / ./ I/ � / / i t � i //� / /f/ / / / r / / / �l f �rr r J � � � l � / 1 l �. ,� / f �e i i / I I r 1, / / y / /// / / / / / / I/! l // r ,� ,, / I r // /� / // / r � I / y � /� t i //� � / / l � , , / r l P � � / � / / / / / � r / ,, � / � / / ,/ , // l G / � / / r , 1, � / 1 � I ' i � i l/ i � � I/ � � � / I /i � r l ,f � 91 T , / � �' � / � � /,, r �' r/ � r � / � f /1 /i � / / / / /� r � � � >' i 1 � / / r / � ! ,, � / �' � f // � r /, � �, � � i , , /� � � r f f , �� i � e , /� �` �/ � / ,� � I � � I � � , � 1, � � � � t �r� a � � , , � � , �� � � � � � � � � �` �!/ v ,, / � , � � / � � , / / � ,, f ,, � � J � f I � � , �,� � � � � � I � ! ,> > � ,�, � , / � � , , , , � y , � ,� , / � o �, 1, ,,1 �� f r�, � �, / / r � r � / I / /,� � y � I � / � r l � / � j � / (, / � I �� 1 � /, l � � l � � , ! / � �r � /, , / ��, i i, , / � �, f� � >' f / � , ,/ i '/ / / /r � , � � / / i � / r � r / � � �, /�� J � � �/ 1 , / / % ,/ / � / l �l / � / � / �,/i / / / f „ - A � � r / �, / I/ /, 1 � �, � � / / / / i l � � , I, r / � l >'J � /� � / / / r/ / / , �� / � � / / � / f, � , � � , � r � � / f � i � � .. � � ,, i � � � , f t � f � ,/ �/ r / >' f / � � � , , i� � , , � � t �� , , , � �� � I � T � � �� � �,� i '� / / � /' e a / / / � / / / l / /, / � 1 / / I r � / / / �/ �� � / , � �� t� � l r �, „l n....:.. rr� ,l'„ ,.l.,. i rr ,... .I i n .r �, ,..,.y .. l� ,/.�.o .. . ,..1,. ..,../ r,p ,.. ..r ,. !� I � / / � i" � r/ I y r, i ! , 1 r 1 / , l fl � � � � r ��i I / i r it i /, � / r r r Or � / / // i /� ,1 r i 1 � f / 1 I ( /� l / r / / i, i�r l // rt � / / / / // 1/ % // l � / // � l f �/ / / l // /J i l/ // J / % / � / / / / / r i I / / // ` , , � / � I, / 1 r � � ,, / / „ J / l � ///J�� % �/, l//i/ /� ,/ l/�/, l; /,� , //i // G,// . ,, 1, , , t / � �// r� i.,, l Vii, /I /�. . r,. r ,..,re .... � i ,,, �.,.�.r / ... ,,, � ,,., r..,.r,itr. ..r �I ...� ,/.../. i.�,r i / . .
