<br />SAN JUAN/DOLORES BASIN <br /> <br />Sep-05 <br /> <br />Basinwide Conditions Assessment <br />The SWSI value of +0.8 indicates that for August the <br />basin water supplies were near normal. Flow at the gaging <br />station Animas River near Durango was 545 cfs, as <br />compared to the long-term average of 552 cfs. Storage in <br />McPhee, Vallecito, and Lemon reservoirs totaled 121% of <br />normal as of the end of August. <br />August started with signs of a break from the dry <br />spell experienced in July. Storms brought needed moisture <br />into the division culminating with a major event on August 81h <br />with almost an inch of precipitation in Durango. The rains <br />were sporadic and distributed so that some areas received <br />more than others. After August 16 no precipitation was <br />recorded in Durango, although some mountain areas <br />continued to have thundershower activity. Durango ended <br />the month with 73% of normal precipitation (1.86 inches), <br />bringing the water year total down to 115% of normal (20.1 B <br />inches). <br />Temperatures were fairly warm. Daily lows were 4' <br />above the 100-year average at 52.9'F in Durango. <br />Some rivers rose slightly, although in general ran <br />slightly below average for the month. The Dolores River <br />finished Its Groundhog releases early and fiows at the <br />Dolores gage dropped significantly to about 120 cfs at the <br />end of August. <br />Reservoirs continued to hold up on storage staying <br />above average at, the .major reservoirs, across the area. <br />Vallecito Reservoir still contained 95,OOO acre-feet at the end <br />of the month, 137% of average. <br /> <br />Outlook <br />The outlook is for continued dry conditions, as it <br />appears the weather cycle of non-productive storm <br />development similar to the past several years is the current <br />pattern, This could change quickiy, however. It does appear <br />that ample water will be carried over by the reservoirs into <br />next year. <br /> <br />Public Use Imoacts <br />Normal summer activities continued with fishing use <br />being observed In many areas. River sports continued and <br />the mountain springs continued flowing for the most part. <br /> <br />~~ <br /> <br />w <br />~ <br />f <br />-., <br />~. <br /> <br /> <br />~ ' <br />~ <br /> <br />. <br /> <br />JIrl..W.IiinQB.,gHl9Jln.C1lJ;n.OtJn.Q2J;r,.CO~.8lO5 <br /> <br />-,- <br /> <br />~FI'o.ffitR I:1.RA'lXl RDNBV\llAlER'f'5tlR <br /> <br />1,an,(XX) <br /> <br /> ---- ,..-- <br /> (/ <br /> / <br /> j ,..-- ,..-- <br /> /" <br /> ~ / <br />---- ,..-- <br /> <br />Jj"""" <br />} <br />~ fID."" <br />It <br />~4lD.<ID <br />:s <br />" <br />" <br />B= <br /> <br />o <br />QtN),t[b:..B1FebMl'd1JptMrj.b1eJ.Jyh.uSeP <br /> <br />-e-\\Er(1973) <br /> <br />-+-CRf(3X!2) <br /> <br />-H"" <br /> <br />*'''''' <br /> <br />REPfij$ENTATIV'E RESERVOIRS <br /> <br />300.000 <br /> <br />".000 <br /> <br /> <br />200.000 <br /> <br />J <br />~ 200.000 <br />'1Ml.OOO <br /> <br />J 100,000 <br /> <br />, <br /> <br />...... <br />_A\g.08fJ10:1nlenta <br /> <br />v._ <br /> <br />"""'" <br /> <br />130&'31m5Cootents <br /> <br />9 <br />
