I lowered my pond by about 2' in about 2 days by simply submerging a 3" air hose in the water, capping one end with my hand and then quickly shoving the other end down the overflow pipe. As I was trying to anchor the intake side the hose latched onto my waders like a leach. Took about 20 or 30lbs of force to get it loose.
