Yes. I work in a marina and have seen them come into the channel and the lake. I have heard that they come inland when the salinity of the water is higher. Where I am the bays and lakes are brackish waters, a mixture of fresh and salt water. When the tide comes in, so do the dolphins in some instances.
Delphinidae for "oceanic dolphins" & Platanistoidea for "river dolphins".

No. It is too far inland.
dolphins usually come to Rehoboth Beach from may-sep.by zara 10 years old
dolphins don't sleep when they get tiered the only thing they do is swim then come out of the water
Dolphins have an opening toward their tails on the bottom side from which waste is expelled.
Dolphins do not have a nationality

Watching dolphins and swimming with dolphins. Or riding dolphins. If you are in swimming and dolphins come around, if you decide that you want to ride one, first make sure it's not a shark.
