The Historic Acequia is situated between the Upper Labor (Lily Pond) and along the north side of the water raceway to the pump house. The Lily Pond supplies the water to the acequia through a control gate on the north side of Brackenridge Road culvert bridge near the upper end on the acequia. The lower end of the acequia by the pump house used to be gated but now open and releases water through the zoo property. The acequia is composed of grouted stone walls and an undetermined bottom. Some of the walls for some length are deteriorating and in need of repair. Many large trees have grown up near the walls and have contributed to the wall deterioration as well as surface drainage from paved areas up slope of the acequia. There is existing asphalt paved parking along Brackenridge Road as well as along a drive abutting the zoo fence line.
