ANEP: San Juan BayThe San Juan Bay Estuary system has provided valuable resources to the residents of the region for centuries. People are attracted to the port, beaches, beautiful parks, and historical and natural areas-these resources are vital to the regional economy. Some endangered, endemic, and/or rare species in the estuary's watershed and associated areas include the brown pelican, the peregrine falcon, the yellow-shouldered blackbird, the leatherback seaturtle and the manatee. San Juan Bay is the only National Estuary Program in the tropics.

Facts About the Estuary

  • Over 622,000 people live in the San Juan Bay watershed, and the average population density is 8,327 people per square mile.
  • The area is home to over 300 wetland plant species, 160 bird species, 19 reptile/amphibian species, and 124 fish species-18 of which are open to sport fishing.
  • San Juan Bay is the 17th largest port facility in the world and the second busiest container port among East Coast ports.
  • The City of San Juan is the oldest within the United States and its historical and archeological features have immense social and cultural value.
  • In 1997, approximately 1.1 million cruise ship passengers arrived in the port of San Juan, and 9.8 million travelers used the Luis Muñoz Marín International Airport.
  • In 1995, over 324,500 pounds of finfish were caught in the estuary.

Health of the Estuary

  • Mudflats, marshes, mangroves, submerged aquatic vegetation, coral communities, and sandy beaches are some of the habitat types found within the estuary. Combined, they support very rich and diverse biological communities.
  • The nature and level of citizen interaction with the estuary is varied. Some citizens frequently engage in recreational activities associated with the estuary such as sightseeing, swimming, surfing, fishing, kayaking, sailing, and jet skiing. The presence of four marinas and ten fishermen organizations facilitate the use of the estuary by yachters, boaters, and fishers.
  • Development of port and air traffic facilities, residential areas, and industrial complexes within the metropolitan area has resulted in the modification and loss of some of the bay's important habitats.
  • Water quality in the bay area has declined over the past century due to urban development and associated impacts such as nonpoint source pollution.

Accomplishments of the Estuary Program

  • In October 2000, the State of Puerto Rico and the US EPA officially signed the San Juan Bay Estuary Program Comprehensive Conservation and Management Plan (CCMP).
  • Several actions contained in the CCMP have been initiated since 1999.
  • The US Army Corps of Engineers (USACE) and the Puerto Rico Department of Natural and Environmental Resources (DNER), have been working on an Environmental Impact Statement to dredge the eastern half of the Martín Peña Channel to improve water flow.
  • The USACE just finished an Environmental Impact Assessment on a project designed to help improve flow between a cove inside San Juan Bay and the rest of the San Juan Estuary.
  • The Estuary Program is working to get Puerto Nuevo River lands added to the Martín Peña Channel area nature reserve.
