On August 27, 2011, Hurricane Irene inflicted damage to the town. Very heavy rainfall caused the Schoharie Creek to surge higher and cause immense widespread flooding. High wind speeds were also present. A small bridge was destroyed, and numerous houses were also washed away by the creek. Farms near the creek were flooded as well. Flash flooding also was an issue. Certain roads that run through the town were flooded and some were damaged. Many homes in Lexington lost power. The Federal Emergency Management Agency arrived in Lexington following the storm. People volunteered for cleanup work and many donated food and clothing. Power was eventually restored to all affected areas.
