Purchase a diverter. They install in the downspout and have a float so when the barrell is full the float diverts back to the splash block. Usually about 30 dollars.
I don't know what divert means but, well, I live in Colorado and... as far as I know, I don't divert my water...
You don't, a roof drain is nothing more then a conductor that allows water to enter the storm water piping and then the piping leads to a place of disposal.
A chimney cricket is a sloped structure added to a roof upstream of the chimney to divert rain water away from the chimney. They are installed to reduce the amount of rain water that may enter the house if the sealing around the chimney fails or is less than perfect.
In open fields some rain water makes its way through the ground to the water table. Other water drains across the fields to streams. Some of that water drains down to the water table. Many cities no longer permit rain water to percolate into the water table but divert it to storm sewers. That water then goes either to rivers downstream or out to the ocean.

A by-wash is an outlet from a dam or a reservoir, or a cut to divert the flow of water.
We can make good use of rain water by storing rain water and by rain harvesting.
Rain IS water, it does not turn into water.
