Effect of an enormous waterfall on regional climate and ecosystem

My premise is that a bay-like body of water empties into a sea via a waterfall.

Specifications: The sea is roughly the size and shape of the Mediterranean. The tributary body of water is around 20 miles across, and very long (shaped like a huge river). The waterfall is a straight drop of about half a mile (roughly the height of the tallest waterfalls on earth). It is fresh water flowing into salt water. It's not flowing extremely quickly, but the rate of discharge is sufficient to create a continuous curtain of water extending all the way to the bottom.

Things to ignore: Erosion is not an issue. Don't worry about the source of the water either.

Obviously, the waterfall would generate large quantities of mist, much of which would evaporate into the surrounding air. It would also cause turbulence in the sea and an area of diluted salt water. What effects are these factors likely to have on the weather, sea currents, and aquatic life?
