History

Bounded by the Atlantic Ocean and the Intracoastal Waterway (Tolomato River), the Guana Tract, which includes the Guana Tolomato Matanzas National Estuarine Research Reserve (GTM Research Reserve) and Guana River Wildlife Management Area, comprises some 12000 acres (48.6 km²) of public conservation and recreational uplands.
The land was purchased from Gate Petroleum

 with Conservation and Recreational Lands and Save Our Coast funds by the State of Florida in 1984 and divided into Guana River State Park and the Guana River Wildlife Management Area. In 2004 with the construction of the GTM Environmental Education Center, the management of the state park lands was turned over to the GTM Research Reserve to manage as part of the larger research reserve.
The tract was privately owned and open to the public for hunting and fishing prior to state acquisition. During the period of private ownership, the Guana River was dammed in 1957, to flood the upstream marshes in order to enhance wintering waterfowl habitat. The result was the creation of the present-day Guana Lake. The lake water is brackish near its southern terminus at Guana Dam and gradually turns into a freshwater reservoir as one travels away from the dam. Both saltwater and freshwater fish species exist in the same body of water.
