Ogeechee Riverkeeper

The river system drains over 5,000 square miles of land. The Ogeechee River watershed includes 4 sub-watersheds: Upper Ogeechee, Lower Ogeechee, Ogeechee Coastal and the Canoochee watersheds. The freshwater streams in this river system are known as blackwater streams due to their dark, tea-colored water. The tannins from the swamps that stain the water also make it more acidic than other streams. This acidity reduces the amount of vegetation that can grow naturally in the rivers, and also affects the mercury uptake by fish. Ogeechee Riverkeeper works on all of the streams flowing out to Ossabaw Sound and St. Catherine’s Sound

Emily Markesteyn became Executive Director for Ogeechee Riverkeeper in April 2011 and in 2014 became Riverkeeper. She was born and raised in Savannah, GA. Her love for the water began in the tidal creeks learning to water ski, kneeboard and go tubing with her family. Emily is responsible for education, monitoring and advocacy activities to promote water quality. She attended Emory University in Atlanta and graduated with a Bachelor of Science degree in Environmental Studies in 2003.
