Yeah ... the dam is only spilling at a little over 500cfs and has been for the last few days. The "incoming" rate is around 15,000cfs
But, after almost 7" of rain in the Green River Lake drainage area this month, plus the downstream flooding .... it's gonna be this way for awhile.
But, as you can see on this chart .... check the March inflow/outflow .... if they can maintain a spill rate of 7000cfs for a couple of weeks, they can get it back down to Winter Pool (barring any periods of heavy rains during that time)
