The animal was spotted in the river close to the Lifford Bridge in the area on Sunday by local fisherman Danny Hunter who was out walking.
At the time Danny told UTV: "I was shocked, you would not think to ever see a dolphin at all in the Foyle, especially off the Boghill Road in Strabane, 35 miles away from the sea."
It was thought the animal had got trapped in the river because of the low tide.
And when news of the dolphin's appearance spread, hundreds of people swarmed to the area to catch a glimpse which led to it getting the name, the Foyle Flipper.
Danny, who runs a local fishery, said the rare sighting was the talk of the area and far beyond.
He added: "People were coming down to the area in their droves to see it.
"There were cars parked all over and when it was on the news even more people came.
"My wife works in Altnagelvin and everyone was talking about it up there."
However, on Wednesday, the animal was found dead washed up on an island in the river.
Danny added: "It's sad, people have still been coming to see it and have found it dead - there are kids in floods of tears.
"The really sad thing is, is that today was a high tide and it probably would have been able to escape and swim back to the sea.
"It's sad and strange and I just hope a lesson has been learned.
"But there is so much wildlife here. We have seals, otters, and kingfishers. People don't seem to realise there is such great wildlife on their doorstep."
