Help me design some duck habitat

There is a long creek running through our property. It begins to open up before going thru a pasture portion. Probably 12-15 feet wide and 2-3 feet deep here.





Here it leaves the woods and enters pasture. I did a little tractor work today removing a log jam.



I want to start this project around February and get it done before the end of spring so that the creek will have time to fill back with water before summer hits.

Once the creek enters the pasture is gets smaller for most of the way 1-2' in width. Basically just a drainage basin.



It does open up some more along the way and form small pockets of deeper water.





I basically want to use a dozer to open up the creek on the small portions of the pasture and make the entire creek the same width (15 or so feet). Then be able to launch a small jon boat from pic 1 w/ a surface drive and be able to run up and down the creek.

Then create a rice field to the left of the creek in pic 4. Here's a picture looking back towards the creek across where I would theoretically have the flooded rice field.



I figured I could use the creek for transportation and also a water source if the field needed it.

My questions...

Does this look like a good plan?

Would you connect the field to the creek so you could just drive a boat straight from the creek to the blind? Or levee off the field on all sides and keep it seperate from the main creek?

What would you do differently in order to optimize duck habitat? I usually see woodies, spoonbills, wigeons and the occasional mallard on our cow ponds.
