PHOTOS: Rookery Bay’s estuary day was a blend of fun, knowledge
An estuary is a partially enclosed body of water where two different bodies of water meet and mix. Rookery Bay — which includes 110,000 acres of land and water— is a mangrove-forested estuary filled with fresh and brackish water, which is a mix of fresh and salty seawater. Another type of estuary, a freshwater estuary, is found where rivers or stream water mix with lake water.
