The USDA Natural Resources Conservation Service June Water Supply Outlook indicates June through September streamflow forecasts in the Hood, Sandy, and Lower Deschutes basins range from 69 to 71 percent of average.  NRCS Snow Survey Supervisor Scott Oviatt says early snowmelt resulted in streamflows peaking sooner and beginning to recede to mid-summer levels up to four weeks early.  However, he says water year precipitation has been at 111 percent of average in the basins, boosting reservoir levels that were at near record lows at the end of last summer and painting a much better picture for water supply this year.  But Oviatt says if the summer is hot and increases demand, water users drawing from reservoir sources could still experience possible water shortages.  As of June 1, only two monitored sites in the basins still have snow, which is not unusual for this time of year, but due to warm spring temperatures, most sites melted out 1 to 3 weeks earlier than normal.
