I I I I I / ( I I I I ! I I , c~ .-) ~ e,;\ QO The study showed CAP to pump an aver~ge 1,466,000 acre-feet annually for 64 traces over the period 1986 through 2050. Average CAP pumping for each year from 1986 through 2050 is illustrated in figure C-2. IMPACTS TO CAP WATER SrpPLY Figure C-2 shows a consistently declining average CAP pumping from 1992 through about 2040. After 2040, the average pumping appears to stabilize through 2050. CAP does not experience a declared shortage until 2016 when one is declared among 64 traces. From 2016 through 2050, CAP experiences inc~easing occurrences of shortage (see figure E-4). CAP incurred declared shortages most frequently (17 times) in 2048. Occurrences of declared surpluses and of CAP pumping above its normal schedule behave simil~rly and are illustrated in figures E-5 and E-6. These frequencies generally decline from 1992 through about 2025. After 2025, the frequencies remain at about 5 and 6, respectively, of 64 possible for declared surplus and pu~ping above the normal schedule. I~WACTS TO METROPOLITAN WATER SrpPLY T"e study showed Metropolitan annual pumping to average 637,000 acre-feet for 66 traces over the period 1986 through 2050. Average Metropolitan pumping may be seen in figure C-1 to decline from 1986 through 2025. As it declines, the rate of decrease becomes less as 2025 is approached. After 2025, Metropolitan average annual pumping remains between 556,000 and 570,000 acre-feet through 2050. Figure E-2 illustrates the frequency of Metropolitan's pumping above its normal schedule. Similar to the decline in average pumping, pumping above normal schedule declines in a like pattern through 2028. After 2028, pumping above the normal schedule remains at roughly 6 occurrences of 64 possible. IMPACTS TO ROBERT B. GRIFFITH (SNWP) WATER SUPPLY The study showed SNWP annual pumping to average 240,000 acre-feet for 64 traces 1986 through 2050. Average annual SlfWP pumping is illustrated in figure E-7.
