This morning Boat 3 was requested to assist Bay District (St.Marys) with a Water Supply drill. Boat 3 meeted up with units at the end of Green Holly Rd in the Town Creek Area. Crew from the boat created a draft operation from the Patuxent River and fed a line off the deck gun of the boat to a line to Engine 91 bypassing their pump which was continuously dumping into a folding tank, which was supplying a line to a tanker filling up. We would like to say thank you to our Brother from St Mary's for the invite.
