HMDA safeguards lakes, canals, and reservoirs with two regulated rings:
• FTL (Full Tank Level): The highest water line the waterbody can reach at full capacity.
• Buffer Zone: A no-construction safety belt around the FTL (30 m for lakes > 10 ha; 9 m for smaller lakes & nalas).
Hydra overlays these boundaries on cadastral maps so you can verify compliance in seconds instead of combing through manual HMDA PDFs.
