Upper Floridan Aquifer Potentiometric Surface Map for West-Central Florida, September 2007

A U.S. Geological Survey map report shows the potentiometric surface of the Upper Floridan aquifer in west-central Florida for September 2007. This dataset represents water-level conditions near the end of the wet season and is part of a semi-annual series of maps produced since 1964. The data were collected primarily by the USGS during September 17-21, 2007, in cooperation with the Southwest Florida Water Management District.

Use Cases

• Modeling groundwater flow based on the potentiometric surface elevation data.
• Assessing seasonal water-level highs for the Upper Floridan aquifer in September.
• Analyzing the impact of rainfall deficits on aquifer levels based on the reported 13.42-inch shortfall.
• Supporting water supply planning for public, agricultural, and desalination uses as described.

Strengths

• Data collection is part of a long-term series with maps for May and September each year since 1975.
• Report provides specific context, noting the cumulative rainfall was 39.50 inches, 13.42 inches below the historical average.
• Prepared by the authoritative U.S. Geological Survey in cooperation with the local water management district.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• The description notes measurements were taken over a 5-day period and do not represent a snapshot at a specific time.
