What this tracks
This dataset maps the location, size, and type of wetlands, lakes, and other water habitats across Tennessee.
Why it matters to you
If you’re buying property in Tennessee, this data shows whether wetlands exist on or near your land, which could restrict development or require special permits. Developers and contractors use this information to avoid costly project delays since building in or near wetlands requires federal approval. The data also helps residents understand flood risks, as wetlands naturally absorb water during heavy rains.
How to read this data
WETLAND_TYPE — describes what kind of water feature it is, with values like “Lake” for open water bodies or codes for different wetland types. ACRES — shows the exact size of each wetland area, with sample areas like 10.93 acres helping you understand the scale of water features near you. ATTRIBUTE — provides detailed wetland classification codes (like “L1UBH”) that environmental professionals use to identify specific habitat characteristics.
