A sign on the Roaring Fork river warns rafters of upcoming rapids.<\/strong>

A spate of warm weather predicted for the next several days is likely to prompt high flows for this time of year in the Roaring Fork River and other area waterways, forecasters and river watchers said this week.<\/p>\n

That\u2019s because the snowpack in the high country remains huge for this time of year, said Valerie MacDonald, Pitkin County\u2019s emergency manager.<\/p>\n

\u201cIt\u2019s mind-blowing,\u201d she said Thursday. \u201cIt still looks like winter in a lot of places.\u201d<\/p>\n

A June 20 National Weather Service model of the snowpack \u2014 which was the last snowpack forecast of the season \u2014 shows most of the high country around Aspen and in Colorado between 200% and 500% above normal. And that was before last weekend\u2019s snowstorms came through.<\/p>\n

\u201cWe do expect (the Roaring Fork) to come back up again,\u201d MacDonald said. \u201cWe want the public to be aware that the rivers are high, fast and cold. It\u2019s not the time for an extended swim in the river.\u201d<\/p>\n

High temperatures in the Aspen area are expected to remain in the high 70s and low 80s for the next several days, according to forecasts.<\/p>\n

On Thursday, the Roaring Fork River at Stillwater Bridge east of Aspen was running at about 400 cubic feet per second, said April Long, Clean River Program manager for the city of Aspen. The river is expected to rise to between 600 and 650 cfs in the next three days or so and remain at about that level for the next week, according to predictions by the Colorado Basin River Forecast Center.<\/p>\n

And while that is roughly the river\u2019s historic level at about this time of year, generally the rivers are decreasing in flow now rather than rising, which is what\u2019s happening, according to Long and historical data on the CBRFC website.<\/p>\n

\u201c(The Roaring Fork) will be higher than normal because it\u2019s going up,\u201d she said.<\/p>\n

Greg Smith, senior hydrologist with the CBRFC, agreed with Long.<\/p>\n

\u201cWe\u2019re expecting flows to rebound but they will not be as high as the peaks that occurred previously,\u201d Smith said. \u201cNext week through the (Fourth of July) the peaks will probably be around 700 (cfs).\u201d<\/p>\n

The river peaked above Aspen on June 21 at about 900 cfs, he said.<\/p>\n

Smith said he expects higher flows in the river through \u201ca good part of July\u201d because of the large snowpack.<\/p>\n

Several variables affect how much water is in the river, Long said.<\/p>\n

Those factors include how warm it gets, how quickly temperatures rise, whether water is being diverted to the front range from Grizzly Reservoir and, eventually, the monsoons, she said.<\/p>\n

\u201cWe could see bigger flows with rain on snow,\u201d Long said.<\/p>\n

The Twin Lakes Reservoir and Canal Co., which owns Grizzly Reservoir and operates the diversion tunnels underneath Independence Pass that send water to the Front Range, has not yet decided if and when it will stop the diversions, MacDonald said.<\/p>\n

\u201cThey will keep us appraised of releases,\u201d she said.<\/p>\n

The flows in the Roaring Fork will be even bigger downstream after the confluences of Hunter Creek, Maroon Creek, Castle Creek and the Fryingpan and Crystal rivers, Smith and Long said.<\/p>\n
