On May 1, the Colorado Basin River Forecast Center projected 3 million acre feet of runoff into Lake Powell from Aril 1 through the end of July. This was bad. Then it started raining.
On June 1, the forecast was increased to 5 million acre feet.
As of late last week, the estimate actual inflow was already 5 million acre feet, with more than a month to go. This is good.
