draining a 1 acre pond

i have a 1 acre pond, around 10-12 ft deep at its deepest point. i want to
drop a 5/8" garden hose into it, start a siphon (got plenty of downhill to
work with) and drain this pond down to around 5 ft. has anyone out there
attempted such a feat and if so, how did it go? if a single hose won't do
it, i'm thinking of adding a 2nd and then a 3rd, etc until i get adequate
volume going out. obviously, i'd like to do it w/ less hoses if possible.
