SYLVAN BEACH, N.Y. (WUTR/WFXV/WPNY) – With the help of the Oneida Indian Nation, The Cove at Sylvan Beach held its grand opening on Tuesday, June 28th. This new lakeside vacation destination is designed for weeklong getaways on Oneida Lake, with each cottage featuring its very own pontoon boat. In fact, that’s even how today’s speakers arrived.
