Emergency management officials said the eveningtide brought fewer problems, but they worried about getting through Friday morning's high tide before the storm was expected to wind down.
After being stuck in murky low-tide waters for most of the day, the Common Dolphin passed away Friday evening, according to Joanne Biegert of the Riverhead Foundation.
However, as a high tide of 9.6m (31.5ft) was predicted for Thursday evening at 21.25 BST and even higher tides for the end of October, permanent repairs have not yet been arranged.
