South Bay (Texas)

South Bay is a shallow, crescent-shaped bay located on the Lower Laguna Madre in Cameron County, Texas. It is situated near the U.S.-Mexico border and connects to the Laguna Madre through a narrow channel.

South Bay is known for its diverse ecosystem, supporting a variety of marine life, including fish, shrimp, and birds. It is a popular location for recreational activities such as fishing, birdwatching, and kayaking.

The bay's hydrology is heavily influenced by freshwater inflows from local watersheds and saltwater exchange with the Laguna Madre. The salinity levels in South Bay can fluctuate significantly depending on rainfall and tidal patterns.

South Bay is part of the Laguna Atascosa National Wildlife Refuge, which aims to protect and preserve the area's natural resources and wildlife habitat. Efforts are ongoing to manage water quality and prevent pollution in the bay. The bay is vulnerable to environmental threats such as hypersalinity, caused by limited freshwater inflow, and coastal development.
