REHOBOTH BEACH/LEWES, Del.- Coastal Towns are now calling for the canal that travels from Lewes to Rehoboth to be dredged. Four towns along the coast are sending a letter to congressional delegates in the First State looking for funding to perform maintenance on the the canal. Not only are they saying it's long overdue, they're saying it's impacting the full potential of Lewes-Rehoboth Canal. Rehoboth Beach, Dewey Beach, Lewes and Henlopen Acres all sent a letter to State Representatives asking for the canal to be dredged. Parts of the letter say the cities are concerned with the lack of maintenance for the canal since it was last dredged in 2002, nearly 20 years ago. It also says that the canal barely meets the demands for the boating public, due to heavy silt, and an unreliable depth. The letter asks for the representatives to consider the future of the Lewes and Rehoboth Canal if it was at its full potential. Rehoboth Beach Commissioners talked about this at their meeting last week, and one commissioner was in full support of the topic.
