Raritan River Flounder
Fished on the south side of Parkway bridge in the channel and cought two 18 in flounders and five 14-17 in. shorties.
I forgot to add this before. The water is both salt and fresh water, which they call brackish water.
The salt level is lower than normal salt water, so certain fish can live in the brackish water.
Hey I live right by the rariatan river. It's not saltwater. Wouldnt suprise me if there were some flounder by the mouth though.
