The historic Upper Labor Dam and Acequia are 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 was once gated but now open sand releases water through the zoo property.

The acequia is composed of grouted stone walls and an undetermined bottom. Some of the walls 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.
