This is correct, and no fun. Get your diversions built and if your not in a hurry, see how it goes, might dry up good when you don't have water running across it.Sounds to me like you need it professionally tiled with perforated plastic drainage pipe installed with a laser guided tile plow. Lots of outfits out there that do that. They will plot the field, determine the best collection point to drain to and install the plastic pipe.
Unless you want to work the land for some other reason like getting it smooth enough for a riding mower, mess with it as little as possible.
Get a good pasture grass on it, and fertilize it in late summer if you can afford it. Next spring mark the wet spots, and plant a willow tree.
Best,
