From Sleepy Hollow Village Clerk Paula MacCarthy:
The New York City DEP will be temporarily shutting down the Catskill Aqueduct from
4 pm on June 12 to 8 am on June 13
and from 4pm on June 14 to 8 am on June 15.
During these times, all residents are urged to conserve water and shut off all sprinkler systems. (Helps that there's rain in the forecast.)
