Flooding a field

I am finally going to try to flood my field for duck hunting this year. It will be in corn, and thought about leaving an acre or two standing. There is a 31.5in culvert at the corner of the field to drain the water. I wanted to know if any of you guys have used a flash board riser system for water control, and how it well it worked. This is a photo taken this spring after a big rain.

I flood 4 different fields one that is about 7 acres with a flash board.  My field is adjacent to the river and works well when the river cooperates.  Cant tell what your water source is or how high you can manage the water.  Some concerns would be how tall your corn is and how high the ears are.  Ideally you would want the water level just below the ears although they will reach for it. Another concern is how level your field is with respect to flooding it.  My field can have 3 feet of water on the back end and only one
foot on the front end.  To compensate I plant a shorter variety of corn in the front and taller corn in the back. Also how long does it
take to fill up - I usually compensate filling the field with a 4” pump.  One last thing I can think of is seepage, rat holes ect. - No sense filling it up if it is going to sive out.  Good luck.

I plan on pumping water from a creek on the other side of the treeline in the picture. I have a pool that is around 3 ft deep with a good amount of water flowing into it at all times. There are 6ft. levees around 2 of the 4 sides. The water depth does vary some though out the field, but in the picture the average depth was around 1-2 feet. I did some math and think with the 3in pump I have I should be able to flood an acre with 1ft. of water in 20-24 hours not factoring in absorption. The soil has a good amount of clay in it so I hope it won’t be a big problem. What is the ideal level of water to flood regular field corn with?

Depends on ear height, we try to plant a shorter variety so as not to get ears that are 4 plus feet from the ground, you want to bring the water up to the bottom of the ear.  Ducks are like people - lazy- they rather swim right up to the ear and feed then reach for it.
check out a field with different water levels, the corn closest to the water level is the first eaten.  For your first year I would flood early
(that is after corn has hardened), it can take 2 to 5 consecutive years to get ducks established in your field, especially if you have
competition.  If you start holding ducks let them get comfortable, and by all means never shoot the afternoons or evenings. Best rule of thumb is in and out as fast as possible and dont bother them the rest of the day, also have 2 or 3 no hunt days every week.

Sounds like some great advice. I will have to start looking into the shorter corn for next year. The hunting will be done with one other person most of the time. Last night, based on the things you said, we decided to only hunt it twice a week if there is any birds in there. Thanks for your help
