Interesting calculation - by my math, 4800 tons equals 153777 CFH or 3,690,654 cubic feet of water per day assuming 100% duty cycle and 100% utilization. (I think you made an error in your conversion to volume - it should be about 42.7159 cfs based on a cubic foot of water @ 62.42796 lbs)
Spraying this across 5,761,800 sq ft (132 acres), gives 0.6405 cubic feet per square foot per day, or nearly 7.7 inches of water per day. That's a LOT of water! (Good thing Deep Creek Lake is right there

) By comparison, when they run open the tubes for the upper yough, they drain up to about 630 cfs from the lake.
If you could blow 25% average water content snow, this equates to about 30" of snow over the whole area per day! Of course, they can't run at 100% all day, alot of snow lands on areas other than the slopes, there are significant evaporative losses, etc..... But it does explain why the cameras show lots of piles that are 10ft deep after just 24 hours of operation. WaHOOOOOOOO
