It is approximately 18 miles (29 km) long, from unincorporated Orange County to its mouth at Oviedo. It is located within the Middle St. Johns River Basin of the St. Johns River Water Management District. It is similar to the Econlockhatchee, with a forest in its floodplain. As far downstream as Blanchard Park, the river acts like a canal.
