I have a creek that most of the time is about 6" deep and about 3' wide. I have my pasture divided into about 5 to 6 acre plots and the creek runs a zig zag thru most of them. When I walk them ( better for my health ) I have made crossings that keep my boots relatively dry.
I allow the local town to dump concrete refuse at my gravel pit for a fee and I then have made several crossings from the debris. It is nice when a header or smooth section of curbing come in. the area in the middle of this one is about 12" deep and 3' wide. I placed some broken sidewalk up the banks and a footer across the middle. Cheap and the dogs use them as well.
