Watershed Management: Watershed Planning
Bishop and Mullet Creek Watersheds
Both the Bishop and Mullet Creek watersheds are located in the northeastern part of Pinellas County. Both creeks flow east to west for just over three miles before discharging to Old Tampa Bay. The Bishop Creek drainage basin is 874 acres and the Mullet Creek drainage basin is 1,961 acres within the cities of Clearwater and Safety Harbor and unincorporated Pinellas County. Bishop Creek has two branches that merge at approximately the tidal boundary. Mullet Creek also has two branches in the freshwater portion of the creek that merge before the tidally influenced portion on the creek. Both watersheds are highly urbanized consisting mostly of residential land use.
The County partnered with Southwest Florida Water Management District to complete a comprehensive water quality and biological study on Bishop and Mullet Creeks in 2013. The study found that although dissolved oxygen levels in the creek were routinely less than state water quality standards, there was no evidence that nutrients or chlorophyll were causative factors. Healthy fish and benthic communities were reported and it was found that the creeks support recruitment of important estuarine dependent fish species of economic value.
