ARKANSAS BASIN <br />Basinwide Conditions Assessment <br />The SWSI value for the month was +1.3. Flow at <br />the gaging station Arkansas River near Portland was 1331 <br />cfs, as compared to the long-term average of 1163 cfs. <br />Storage in Turquoise, Twin Lakes, Pueblo, and John Martin <br />reservoirs totaled 92% of normal as of the end of May. <br />Outlook <br />Climate conditions were very unusual in May with <br />high expectations for a better than average runoff tempered <br />by low amounts of precipitation and windy, dry conditions at <br />lower elevations. Runoff was slow to start in the Arkansas <br />Basin due to a series of periodic cool fronts that pushed <br />through during the month. Although significant acreage was <br />prepared and planted in May, ditch companies had to rely on <br />large reservoir supplies where available in lieu of the <br />anticipated higher runoff flows that were projected. The cool <br />periods slowed crop growth and pushed back the growing <br />season for some crops. <br />The river call at the beginning of the month was fairly <br />senior at the Amity #1 right of 212111887. The river flows <br />began to increase later in the month to allow a modest shift <br />to the Fort Lyon #2 water right (3/31/1887). <br />AdministrativelManagement Concerns <br />The Bureau of Reclamation continued to move down <br />large quantities of water from Twin Lakes and Turquoise <br />Reservoirs to Pueblo Reservoir to make room for Fryingpan- <br />Arkansas imports through Boustead Tunnel which were <br />anticipated to reach 100,000 acre-feet in 2008; much higher <br />than imports from any of the recent years. The increase in <br />storage in Pueblo Reservoir cause many entities to call for <br />releases of stored water for use prior to any potential spill or <br />to move water to storage in Lake Meredith. <br />Jun-08 <br />ARKANSAS BASIN SUUSI HISTORY <br />4 <br /> <br />3 <br />2 <br />W <br /> <br />1 <br />W <br />J <br />Q <br />~ ~ <br />X <br />W <br />0 <br />z <br />-1 <br />} <br />0 <br />-2 <br />-3 <br /> <br /> <br />Jan-99 Jan-00 Jan-01 Jan-02 Jan-03 Jan-04 Jan-05 Jan-06 Jan-07 Jan-08 <br />MONTHlYEAR <br />1,200,000 <br />1,000,000 <br />L <br />U <br />>~ 800,000 <br />0 <br />J <br />W 600,000 <br />Q <br />~ 400,000 <br />U <br />200,000 <br />ARKANSAS RIVER NR.
