I'm hoping to have it drained down, seined out and killed off by mid-march. That would allow a good 30 days at least for rain to refill partially...I can always pump out of the big BOW if I get impatient. Then it's a matter of stocking up the spring forage and letting them do their thing.
I'm going to build some structure sections now and have them staged so I can strategically place them after the draw-down.
