<br />ARKANSAS BASIN <br /> <br />Basinwide Conditions Assessment <br />The SWSI value of 2.0 indicates that for July the <br />basin water supplies were above normal. Flow at the gaging <br />station Arkansas River near Portland was 1.477 cfs, as <br />compared to the long-term average of 1,664 cfs. Storage in <br />Turquoise, Twin lakes, Pueblo, and John Martin reservoirs <br />totaled 204% of normal as of the end of July. <br /> <br />Outlook <br />The water supply in the Arkansas River basin <br />remains exceptional. Record rainfalls have keep either a <br />very junior call or a free river in effect on the main stem, with <br />fairly junior calls on the tributaries as well. <br />Virtually all storage facilities continue to be full with <br />no large release demands predicted for the near future. This <br />condition will probably continue until next spring. <br /> <br />Administrative/Manaaement Concerns <br />The ability of the Arkansas River to pass high flows <br />through the La Junta area continues to be a concern after <br />dikes were over topped last May by flows of 25,000 cfs. <br />Under current repairs to a dike protecting the north la Junta <br />area, the channel is estimated to be capable of passing only <br />6,500 to 7,000 cfs. With the help of restricting releases from <br />Pueblo Reservoir, a peak of 6,100 cfs,due to runoff from <br />Fountain Creek, was safely routed through this area the first <br />week of August. <br /> <br />Public Use Imoacts <br />The frequent rains of this summer have begun to <br />negatively impact the agricultural community. Farmers and <br />ranchers have had difficulty bringing in their cuttings of hay, <br />and some watermelon crops have already been lost. <br /> <br />Aug-99 <br /> <br />AA<PNSOS BtISIN SVIS HSTCRl' <br /> <br />~ 2 <br />r <br />> 0 <br />~ <br />~., <br /> <br /> <br />>- <br />~-2 <br /> <br />-3 <br /> <br />.. <br /> <br />~ <br />_.....,-------- <br />1.OIIH/'11:AR <br /> <br />ARKANSAS ~ toR F'ClRTl.MQ FlO.'V BY VlAlER YEAR <br /> <br />1,200.000 <br /> <br />200,000 <br /> <br /> .-- <br /> / <br /> / <br /> I v ~ <br /> ~ <br /> ~ '/ <br /> - <br /> -- <br />- <br /> <br />~ 1.000.000 <br />~ <br />~ lm,OOO <br />9 <br />... <br />~ 8Xl,OOO <br />S <br />::l 4100.000 <br />~ <br />u <br /> <br />o <br />Q:l NoY Dee .Ian FS> Mm1,Api1 M9y .lrIe .uy Aug ~ <br /> <br />-e-V\ET(1S64) . .....[R((1977) <br /> <br />.......AVG <br /> <br />......1S!l9 <br /> <br />~FEI!BWRS <br /> <br />3I),lID <br /> <br /> <br />3Il1lD <br /> <br />!3I),lID <br />~ . <br />.lID,lID <br /> <br />JUQlID <br /> <br />Gl <br />Zi <br />~1ClllID <br /> <br />lIltID <br /> <br />J:tnMnn <br /> <br />R8il Tuq.dse <br />II Ag 7131 Clri!l1s 117I31/IJj0:rlsls <br /> <br />"M1Laes <br /> <br />4 <br />
