Historically: 4 million acre-feet/year sheet flow. Now: <50% due to canals, levees, agriculture, development. **CERP (Comprehensive Everglades Restoration Plan)** — $23B, 30+ year project — aims to restore flow, quality, timing.
The Everglades is big, flat, wet, and irreplaceable. 1.5 million acres of "River of Grass" — Marjory Stoneman Douglas's name, and still the best description.
