Sweetwater Creek Watershed Mgmt. Plan 2007 Update--Part 2

CHAPTER 9
Groundwater levels in the Northwest Hillsborough area as represented by three monitoring wells,
(EWWF 11 FLDN, EWWF 2S DEEP, AND COSME 3-FLDN) indicate that groundwater elevations
for March 2006 are declining from those observed in April 2006, but they have not reached the
historical low for March (Table 9-3).

The Northern Tampa Bay Phase II (NTB II) project was initiated by SWFWMD as an outgrowth of
the 1989 declaration of the NTBWUCA and the Northern Tampa Bay Water Resource Assessment
Project (WRAP) which was completed in 1996. This study will continue through 2010 and will
include assessments of the biological and hydrological conditions in Northern Tampa Bay to
support the development of minimum flows and levels, water resource recovery, water use
permitting, and environmental resource permitting. NTB II consists of a series of technical projects
in Northern Tampa Bay to support the ongoing development of minimum flows and levels, water
resources recovery, water use permitting, and environmental resource permitting.
The goal of the NTB II project is to enhance the data collection effort, implement projects for the
assessment of water supply needs, and to develop a water resources recovery strategy. As of
2005, 30 nested groundwater monitoring sites have been installed and 50 new wetland monitoring
sites have been established, many of them in the Northwest Hillsborough area. These projects
include detailed assessments of water resources and involve intensive data collection and
monitoring to characterize hydrologic conditions and determine the effects of water withdrawals
(SWFWMD, 2000).
