What effect does the continental divide have on the direction of river flow in the united states?

The Continental Divide divides the region into two large drainage areas. To the east of the Divide, waters, flow to the Arctic Ocean, to the Hudson Bay, or to the Atlantic oceans through the Mississippi River system. To the West, they flow into the Pacific Ocean. Hope this helps. ;)
