yes they are in the mouth, and right where the fresh water meets the salt water, you can see them bombing around in the high tide. and shooting up the shallows. the lower pool i mean is the one in the most lower part of the fresh water river, at the seymour heritage park. also now there are fish at the next pool too, the one just like a hundred yards from the parking area.
hope this helps.
