<br />ARKANSAS BASIN <br /> <br />Basinwide Conditions Assessment <br />The SWSI value for the month was +3.1 The <br />Natural Resources Conservation Service reports that April 1 <br />snowpack is 141 % of normal. Flow at the gaging station <br />Arkansas River near Portland was 711 cfs, as compared to <br />the long-term average of 368 cfs. Storage in Turquoise, <br />Twin Lakes, Pueblo, and John Martin reservoirs totaled <br />100% of normal as of the end of March. <br /> <br />Outlook <br />Total distributed reservoir storage following the <br />Pueblo Winter Water Program was 153,035 acre-feet, <br />including 53,237 acre-feet in Pueblo Reservoir, 77,075 acre- <br />feet in off-channel reservoirs, and 22,155 acre-feet in John <br />Martin Reservoir (after distribution to accounts). Storage in <br />John Martin Reservoir through March 31, 2008 in <br />conservation storage totaled 26,097 acre-feet. <br /> <br />Administrative/Manaqement Concerns <br />Heavy snowpack in the Arkansas Basin has <br />prompted significant planning in anticipation of potential <br />runoff issues and to manage storage in Pueblo Reservoir <br />and upstream reservoirs in an optimum manner to avoid <br />spills from Pueblo Reservoir while still preserving adequate <br />space for higher than average expected Fryingpan-Arkansas <br />Project water imports. <br /> <br />Apr-08 <br /> <br />ARIWS6S BASlN9/lS HSTCRY <br /> <br />~ <br /> <br /> <br />w <br />::: <br /><t <br />> 0 <br />x <br />w <br />o <br />Z <br />-.1 <br />>- <br />0:: <br />o <br />.2 <br /> <br />.3 <br /> <br />.. <br />J<n-99 Jan-OJ Jcn-01 Jan-02 Jen-03 Jan-04 Jcn-05 Jan-03 Jcn-07 Jan-CB <br /> <br />M:N1H/\S'R <br /> <br />ARKANSAS RIVER NR PORTLAND, FLOW BY WATER YEAR <br /> <br />250, CXXJ <br /> <br /> <br />1D <br />,f 2OJ, CXXJ <br />dJ <br />" <br /><t <br /> <br />~ 15O,CXXJ <br />-' <br />LL <br />W <br />> <br />~ 100,CXXJ <br />-' <br />::J <br />::;; <br />::J <br />U 50, CXXJ <br /> <br />o <br />Cct <br /> <br />Nov <br /> <br />Dee <br /> <br />Jan <br /> <br />Feb <br /> <br />M3rch <br /> <br />--8- V\ET (1934) <br /> <br />-+- DRY (=l <br /> <br />~AVG <br /> <br />"*- 2OJ8 <br /> <br />REPRESENTATIVE RESERVOIRS <br /> <br />250.00J <br /> <br /> <br />2OO,00J <br /> <br />1D <br />2 <br />dJ <br />g 150,(0) <br /><Ii <br />OJ <br />ro <br />o <br /> <br />~ 100,(0) <br />:0 <br />ro <br /><f> <br />::J <br /> <br />5O.00J <br /> <br />John M3rtin <br /> <br />Pueblo <br /> <br />Turquoise <br /> <br />Twn Lakes <br /> <br />II Avg. 3131 Contents <br /> <br />113131/08 Contents <br /> <br />4 <br />
