Watershed Management: Watershed Planning
Long Branch Creek Watershed
The Long Branch Creek Basin is part of the Old Tampa Bay Watershed and it covers an area of approximately 2.8 square miles or 1,800 acres. It is located in a highly urbanized area in central Pinellas County and it is mostly within the City of Largo limits. It is generally located with Allen’s Creek to the north, Cross Bayou to the South, the Starkey Road basin to the west, and Upper Tampa Bay to the east.
Near the headwaters of the stream is Swan Lake, a small lake surrounded by residential homes. The outlet of this lake is one of the main sources of water contributing flow in the stream. The main channel is about 3.3 miles in length and flows to the northeast into Old Tampa Bay. The freshwater stream reach is approximately 2.5 miles in length and flows into the tidal segment of the basin.
