Other Hydrologic Data Sources
In addition to the District’s hydrologic monitoring data, the following are links to other sources of hydrologic information.
USGS Investigative Report – Creating a monthly time series of the potentiometric surface in the Upper Floridan aquifer, Northern Tampa Bay area, Florida, January 2000-December 2009 »
Long-term groundwater monitoring data were used to generate a monthly time series of potentiometric surfaces in the Upper Floridan aquifer over a 573-square-mile area of west-central Florida between January 2000 and December 2009. The mapping time series describes the potentiometric surface beneath parts of six regionally important stream watersheds and 11 municipal well fields that collectively withdraw about 90 million gallons per day from the Upper Floridan aquifer. Includes links to an animation and GIS downloads for the modeled results.
Tampa Bay Water 2017 – Extending the monthly time series of the potentiometric surface in the Upper Floridan Aquifer, Northern Tampa Bay area, Florida, January 1990-December 2015 »
Long-term groundwater monitoring data were used to extend the available monthly-average potentiometric surface maps of the Upper Floridan in the Northern Tampa Bay area to a 26-year period from January 1990 to December 2015. The methods and mapped area are those used by Lee and Fouad (2014) in USGS Investigative Report 2014-5038 to create a 10-year time series. The extended mapping results seamlessly describe 26 years of potentiometric-surface elevations in the years before, during, and after large reductions in groundwater withdrawals from the area’s municipal well fields. Data products include monitoring-well characteristics, times series of groundwater-levels in each of the 195 monitoring wells, and GIS downloads for modeled results.

Ranking the Inundation Potential of Palustrine Wetlands in the Northern Tampa Bay Area »
Tributary streams in the Northern Tampa Bay area flow through thousands of freshwater wetlands before flowing into Tampa Bay, the Anclote River, Pithlachascotee River, and Cypress and Trout Creeks. The Wetland Ranking project maps wetlands that are part of flowing stream channels in different months of the year, then quantifies wetland outflows and other wetland surface-water metrics through time. The inundation potential of wetlands is ranked by combining wetland surface-water metrics with wetland groundwater metrics developed in a previous Wetland Groundwater Conditions project. Monthly-average wetland outflows, surface-water metrics, and inundation-potential rankings are described for the historical period 1950 to 2017, as well as for two shorter periods bracketing years before and after reductions in groundwater pumping within Tampa Bay Water well fields. A report describes the study. A data download includes a geodatabase and provides wetland metrics, inundation-potential rankings, and field-site verification data.

Changes in Wetland Groundwater Conditions in the Northern Tampa Bay Area from 1990 to 2015 »
The Wetland Groundwater Conditions project maps monthly groundwater conditions at 10,516 wetlands in the Northern Tampa Bay area from January 1990 to December 2015. The groundwater condition metric is the vertical elevation difference (in feet) between the potentiometric surface in the Upper Floridan aquifer and the land surface of the wetland. Positive values, when the aquifer potentiometric surface is above the wetland land surface, convey discharging groundwater conditions. Negative values, when the potentiometric surface falls below land surface, convey recharging groundwater conditions. Wetlands are in a 581-square-mile area where the aquifer potentiometric surface is affected by groundwater pumping from 11 municipal well fields. Download full .zip archive (69.1mb) »
