Volunteers will assist our summer “greenterns” in removing water chestnut from the lake. No experience is required. All tools and work gloves will be provided, but please bring your own water. Volunteers should wear clothes that can get dirty and closed-toe shoes. Registered volunteers will receive an email with location details and an insurance waiver one day before the event. Register at Lake Revitalization at Blue Mountain Reservation Tickets, Multiple Dates | Eventbrite. Contact with questions. For last-minute signups or if you do not receive our email, please call our office at (914) 231-4600 or email . Also: July 30.
