The reservoir is currently 57% full andBureau of Reclamation officials predict it will be possible to fill this year if they keep releasing just the minimum downstream for now. Heather Sackett/Aspen Journalism Water forecasting agencies in Colorado have released their April streamflow predictions, confirming what many already knew: Drought and dry soils will diminish rivers this spring. “The main story of this water supply outlook season is the effect of last year’s drought going into winter,” said Karl Wetlaufer, a hydrologist and assistant supervisor with the Natural Resources Conservation Service Colorado Snow Survey. “We are anticipating significantly lower runoff compared with the snowpack because we entered winter with such dry conditions that the soils are going to have to soak up a ton of moisture before it actually makes it through the system into the river.”
