I agree with the above. Rivers can be fun with the kids, just need to keep safety in mind, especially when the flow is higher (after rain, or spring runoff).
What I ended up doing is buying an inflatable. When the kids were small enough, I could take them all out, paddle just beyond the weeds, and get into the action.
The one I have is on sale at Canuck Tire this week:

I added a trolling motor as well, which definitely upscales it. All of this fit into my compact car (including life vests! Don't forget those!), so it made for cheap impromptu fishing trips with the kids.
At Carson, when spinners and flies weren't working, I would rig up a slip sinker rig. It's a single hook with a swivel about 2-3 feet up the line, and use a heavier sliding weight above that. I'd bait the hook with a bait that floats (eggs, powerbait, etc.) So the sliding weight rests on the bottom, and the bait floats a foot or two above it. Like so:
That way you can cast farther (the weights help with getting that extra distance), and you aren't constantly casting over and over again.
