Oklahoma. Come Volunteer and be a part of the USACE team at Keystone Lake. Keystone is a heavily recreated lake with lots of visitation from the city of Tulsa, which sits just 15 miles to the east. We are looking for volunteers who are motivated, hardworking, and good with the public.  Duties will include tasks such as picking up trash, trimming trees, and assisting our guests. Volunteers will be issued a site with full hookup and amenities. Please contact Ashley Novar at: [email protected] or the Keystone Lake Office at: 918-865-2621 for more information.
