<br />ARKANSAS BASIN <br /> <br />Basinwide Conditions Assessment <br />The SWSI value of -0.9 indicates that for April the <br />basin water supplies were nearly normal. The Natural <br />Resources Conservation Service reports that May 1 <br />snowpack is 72% of normal. Flow at the gaging station <br />Arkansas River near Portland was 401 cfs. as compared to <br />the long-term average of 439 cfs. Storage in Turquoise, Twin <br />Lakes, Pueblo. and John Martin reservoirs totaled 198% of <br />normal as of the end of April. <br /> <br />Outlook <br />Reservoir storage levels remained high during April. <br />Pueblo, John Martin and Trinidad reservoirs averaged 95% <br />of conservation pool capacities. <br /> <br />Administrative/Manaoement Concerns <br />Entities owning water in the Pueblo Reservoir <br />seasonal conservation pool spilled water in April in order to <br />evacuate water out of the fiood pool. Approximately 3,900 <br />acre-feet of Winter Water and 2,529 acre-feet of If and When <br />contract water spilled over a three day period. <br /> <br />Public Use Imoacts <br />The spill in April provided the Bureau of Reclamation <br />with an opportunity to test the Safety of Dams repairs work <br />at Pueblo Reservoir. Releases up to 5,000 cfs were <br />successfully accomplished with no problems noted. <br />Winter water storage commitments during the first <br />part of April reduced outflows from Pueblo Reservoir and <br />allowed several canal companies to repair diversion <br />structures damaged during last year's fioods. <br /> <br />r <br /> <br />May-OO <br /> <br />~Bol.SINS\I\GIHsrCRY <br /> <br />. <br /> <br />. , <br />< <br /> <br /> <br />.. <br />3 <br />< <br />> 0 <br />x <br />. <br />o <br />;;;;., <br /> <br />> <br />g;-l <br /> <br />, <br /> <br />.5-"- <br />""91 ..,.9;2 ......93 ......94 .....~ Jr.-ll6 Jln.9' .....9& _99 JIn4l <br /> <br /><(NTHI"",, <br /> <br />.4RK.AN&\S RIVER ~ F'Cffi1A/\O, FlON BY 'NA.TER YEAR <br /> <br />l.200,COO <br /> <br />..-..... __....n ---1--'-- --']---r ._.~- - <br /> I <br /> I / ? <br /> / , <br /> , <br /> / A , <br /> // - <br /> , <br /> -' <br /> <br />~l.00J.oco <br />. <br />'I <br />~ BlJ.OCO <br />g <br />~ <br />w fOO,COO <br />> <br />~ <br />< <br />~ <br />~ 400,0:0 <br />:> <br />u <br /> <br />. <br /> <br />2lXJ.<XXJ <br /> <br />o <br />O:lt'bfce:,a,F€bMRtl~tv'eyJ..n!JJyA..gSel::c <br /> <br />-e- 'A€T' (1S64) <br /> <br />__CRY{19n) <br /> <br />~AVG <br /> <br />-><-2OXJ <br /> <br />REPRESENTATI'vE FeiERvORS <br /> <br />"''''' <br /> <br /> <br />"""" <br /> <br />di250.OOl <br />~ <br />. <br />b <br />~200.00l <br />. <br />~ <br />. <br />. <br />i.i5150.axJ <br />. <br />D <br />~ <br />~ lOO,OXl <br /> <br />~"" <br /> <br />. <br /> <br />J:tr1MWn <br /> <br />"""0 <br /> <br />.Avg.4i3lCOllerts <br /> <br />r"""", <br />O""",,Ca;e;, <br /> <br />Twnlal<es <br /> <br />4 <br />
