What do you wanna know????
About the only boating in Omaha is on the Missouri River. The river is a pretty good time and where. A couple of bars/restaurants and one nice restaurant just outside of downtown Omaha. The water is pretty dirty/muddy. There are a few other smaller lakes mainly used for skiing.
Lincoln has a few small lakes nearby, but nothing you couldn't boat all the way around in 30 mins. Mainly for skiing and fishing.
LOTO is a 6hr drive away.
Anything else, just ask or send me a PM.
