2021 Map of Gum Slough

About this map

Gum Slough and the surrounding wetlands define this modern landscape where the borders of Indian River, Okeechobee, and Saint Lucie counties converge. This 2021 survey illustrates a region dominated by vast drainage networks and conservation efforts, characterized by the Fort Drum Marsh Conservation Area Trl which winds through the western half of the map. Unlike the dense residential development common elsewhere in coastal Florida, this area remains primarily structured by a rigid grid of rural roads and water management features. Isolated landmarks such as Sick Island emerge from the marsh, providing a glimpse into the natural topography that existed before the widespread canal systems of the 20th century. The map tracks the transition from open conservation lands to the organized agricultural and drainage tracts along NE 304th St and 162nd Ave, reflecting contemporary land use in this tri-county interior.
