Description:"Laguna Guánica is a natural freshwater wetland and lagoon located in Barrio Arena in the municipality of Guánica, in southwestern Puerto Rico. Prior to drainage the Laguna Guánica system actually consisted of two major components, Laguna Guánica and Cienaga El Anegado, a freshwater herbaceous marsh dominated by cattail (Typha dominguensis)...These wetlands were drained in 1955 as part of an agricultural development project in the Lajas Valley. Due to poor soils and other limitations the area of the former lagoon and its associated wetlands has never enjoyed high agricultural productivity, and the present land use is predominately poor quality pasture. The National Oceanic and Atmospheric Administration (NOAA) desires to restore water levels in the Laguna Guánica area to reestablish natural wetland conditions and functions insofar as possible so that the lagoon and its associated peripheral wetlands may be restored to a freshwater wildlife habitat. Following restoration, the lagoon system would complement other wildlife resources in the region including the salt flats at Cabo Rojo, Laguna Cartagena, and the Boquerón Forest and Wildlife Preserve. The restored lagoon could also produce socioeconomic benefits such as ecotourism opportunities, and both passive and active recreation such as nature observation and fishing. NOAA desires to restore the Laguna de Guánica into a wetland and wildlife habitat. As a limitation, it is desired to restore water levels in the lagoon area without causing flooding of the Cienaga el Anegado area immediately upstream of the Guánica Lagoon, due to land acquisition limitations which have not yet been resolved in that area. Several types of problems must be addressed for the successful restoration of the lagoon and the maximization of its value as wildlife habitat"--Introduction.
