GRAHAMSVILLE, NY — A presentation by Adam Bosch from the New York City Department of Environmental Protection on the repairs to the Delaware Aqueduct will be held at the Time and the Valleys Museum on Tuesday, April 21 at 12 noon. Built between 1937 and 1944, the 85-mile Delaware Aqueduct carries water from the Rondout Reservoir to New York City, and is the longest continuous tunnel in the world. It is currently under repair for leakage. Bosch will discuss the challenges of repairing this important water tunnel that supplies New York City residents with fresh Catskill water, half of its total water supply. Bring your lunch to this free program; coffee, tea and dessert will be provided.

Located at 332 Main St., Grahamsville (State Route 55), the Time and the Valleys Museum is open Memorial Day to Labor Day, 12 noon to 4 p.m., Thursdays through Sundays, and from September to November on Saturdays and Sundays. The museum also has a Local History Resource Center, open Thursdays and Sundays, 1 p.m. to 4 p.m. and a museum shop offering local history and environmental publications, handcrafted artwork and gifts by local craftspeople, old fashioned toys and other unique items.
