The Econlockhatchee River rises in Orange County, flows northward into
Seminole County for a distance of about 5 miles, and thence eastward and northeastward to the St. Johns River. The Econlockhatchee River and its tributaries together with a few creeks flowing into the St. Johns River
afford drainage for the southeastern part of the county. Sweetwater
Branch appears to have been formerly a "lost stream" or "disappearing
stream" such as might be expected in areas where sink holes are present.
It rose about 2 miles north of Oviedo, flowed southward and drained into a sink hole that formerly existed just north of Oviedo. At the present
time Sweetwater Branch drains northward through a ditch into Lake Jessup.
