About this gauge

USGS gauge 02302500 sits on Blackwater Creek and reads everything draining 110 square miles of the Hillsborough basin. Its datum sits essentially at sea level NGVD29. Daily flow has been on record here since 1952, 74 years of it.

Where this gauge sits in the drainage

No gauged site sits above this one on the mainstem, so this is the first published reading on the river. Downstream the next reading comes from Hillsborough River at Morris Br near Thonotosassa FL at 375 square miles, so what passes this gauge is about 29% of the water measured there. Water passing here goes on to Hillsborough River near Tampa FL, Hillsborough River at Fowler Av near Temple Terrace FL and Hillsborough River at I-275 Bridge at Sulphur Springs FL.
