>>>>the 4 inches per hour is a foot every three hours. Monday morning to Wednesday morning is 48 hours divided by 3 hours = 16 feet draw down. Not quite the 50 feet they wanted.
Hopefully the 50 feet is a conservative estimate.
“Okay guys, we can get by with 15 feet of draw-down, but lets have a safety factor of three and try to get it to about 50 feet.”<<<<

Actual level, and history:

It’s dropping 5 in/hr, will probably pick up to 6 in/hr.
As the lake draws down the surface area of the lake shrinks. That being said it takes less and less water to lower the lake one foot. After they get past 8 or 9 feet it may take only 15 minute to lower 4 inches.
