How Does the Everglades' 'River of Grass' Actually Flow?

💡 The Answer

• Water moves as thin sheet flow just inches deep across vast sawgrass plains.
• The slow southward drift is powered by a tiny slope of only 2 inches per mile.
• This barely perceptible gradient makes the Everglades one of the flattest places on Earth.
• Seasonal rainfall and Lake Okeechobee overflows feed the slow-moving current.
