Generic picture of water and land ... except, if you look carefully, the grassy area at the bottom is slightly curved. That’s because, on the left is the Ohio River, and on the right is the upper Mississippi. I’m standing at the tip of land in Cairo. Illinois. Across the Ohio is Kentucky. To the far right is Missouri. Right where the two fishing boats are you can see the turbulence where the two currents meet. Although the Ohio is wider and, according to what I read, has a bigger volume of water, on this particular day the upper Mississippi had the stronger current.
