Wesquage Pond (suitable for river herring and white perch) is a coastal barrier lagoon in close proximity to Narragansett Bay. Because there is limited saltwater intrusion, salinity levels range from brackish to fresh. The Strategic Plan for the Restoration of Anadramodous Fishes to Rhode Island Coastal Streams recommends that the passage into barrier ponds requires either natural or manual breaching of the barrier beach at least twice annually at appropriate times to allow migrating adult alewives and white perch access to spawning areas and to allow juveniles to exit the system. A cooperative agreement with the Bonnet Shores Fire District has maintained this passage method.
