Abstract

Hurricane Frances brought heavy rainfall and widespread flooding to southwest-central Florida September 4-14, 2004. The center of Hurricane Frances made landfall on the east coast of Florida on September 5 as a category 2 hurricane on the Saffir-Simpson scale, then moved west-northwestward through central Florida before exiting Pasco County into the Gulf of Mexico on September 6 (fig. 1; National Weather Service, 2004). The hurricane moved across the Florida Peninsula generating 5 to 11 inches of rain over already saturated ground (table 1). Record flooding occurred in parts of Hardee, Hillsborough, Pasco, and Polk Counties (fig. 1). The hurricane and resulting floods caused an estimated $4-5 billion in damage to public and private property (Harrington, 2004), and 23 deaths were attributed to Hurricane Frances (National Weather Service, 2004).

Several watersheds drain counties in southwest-central Florida that were affected by Hurricane Frances. De Soto, Hardee, and Polk Counties generally are drained by the Peace River system, which flows southwestward to Charlotte Harbor and the Gulf of Mexico. Hillsborough and Pasco Counties generally are drained by the Alafia, Hillsborough, Anclote, and Pithlachascotee River systems. Water in the Hillsborough and Alafia River watersheds flows west to Tampa Bay and water in the Anclote and Pithlachascotee River watersheds flows west to the Gulf of Mexico. (fig. 1).

Data Collection

The U.S. Geological Survey (USGS) operates a network of streamflow-gaging stations in southwest-central Florida in cooperation with Federal, State, and local agencies. Data from these stations are crucial for water-supply planning, flood monitoring, emergency response, dam and reservoir-system operation, engineering and maintenance of bridges, roads, and other structures, and are also used to delineate flood-hazard zones. Most of these stations provide real-time data through satellite relay or radio telemetry. Real-time data from these stations are used by the National Weather Service, the Southwest Florida Water Management District, and other agencies and are available on the Internet at http://waterdata.usgs.gov/.

USGS field crews obtained some of the highest discharge (flow) measurements ever recorded at several gaging stations during this flood. These data contribute to understanding flood behavior, enhancing efforts to minimize destruction caused by floods, and providing information for planning.

 

Flood of September 6-14, 2004

Information on peak discharges for selected gaging stations in southwest-central Florida is shown in table 1. The data include peak discharge, peak stage, recurrence interval, rainfall totals, gaging-station period of record, and date and magnitude of the largest historical peak discharge recorded prior to September 2004.

The flooding caused by widespread rainfall and runoff as a result of Hurricane Frances was most severe in the Peace River Basin. Peak discharges for the period of record were recorded at several gaging stations in the upper Peace River Basin (sites 1-9, fig. 1, table 1; Tiger Creek near Babson Park, Peace Creek Drainage Canal near Wahneta, Saddle Creek at State Highway 542 near Lakeland, Lake Parker Outlet at Lakeland, Saddle Creek at Structure P-11 near Bartow, Peace River at Bartow, Peace River at Ft. Meade, Bowlegs Creek near Ft. Meade, and Payne Creek near Bowling Green). At Peace River at Bartow (site 6), the recurrence interval for the discharge of 4,710 cubic feet per second (ft3/s) was determined to be greater than 100 years (Kathleen Hammett, U.S. Geological Survey, written commun., 2004). At the Saddle Creek at Structure P-11 near Bartow station (site 5), USGS field crews measured 1,550 ft3/s of discharge 2 days after the peak flow. This measurement was used to refine the rating curve that determined the peak flow to be 1,640 ft3/s. The gage height at this site was observed to be approximately 9 feet (ft) higher than base flow conditions (fig. 2). The flooding continued downstream to Peace River at Zolfo Springs (site 10) where the discharge of 8,470 ft3/s was computed. This discharge was the highest since flooding associated with rainfall from the 1997-1998 El Niño. At the Charlie Creek near Gardner station (site 11), a tributary to the Peace River, the discharge was 5,460 ft3/s, and the highest since flooding caused by Tropical Storm Gabrielle in 2001. Discharge at the Peace River at Arcadia station, the farthest downstream discharge site, peaked at 14,600 ft3/s (site 12). This discharge was also the highest since flooding caused by Tropical Storm Gabrielle.

Flooding also occurred in the Alafia, Hillsborough, Anclote, and Pithlachascotee River watersheds. A peak discharge of 9,550 ft3/s was recorded at the North Prong of the Alafia River at Keysville (site 13). This discharge was the highest since Hurricane Donna in 1960, and second highest for the period of record dating back to 1950. At the South Prong of the Alafia River near Lithia the computed discharge was 2,630 ft3/s (site 14), which was the highest for the period of record, which began in 1967. A peak discharge of 10,300 ft3/s was recorded for the Alafia River at Lithia (site 15). This was the second highest flow since Hurricane Donna in 1960. Figure 3 shows a USGS field crew using a bridge crane and Price AA meter to measure the flow at the Alafia River at Lithia station.

In the Hillsborough River watershed (sites 17-20, and 23), peak flows for periods of record were recorded at Archie Creek, North Archie Creek, Delaney Popoff Canal, Delaney Creek, East Lake Outfall at East Chelsea Street, and at Hillsborough River at Morris Bridge Road. At Blackwater Creek near Knights (site 21) a peak discharge of 3,140 ft3/s was the highest recorded since the 1997-1998 El Niño. A peak discharge of 6,410 ft3/s at Hillsborough River near Zephyrhills (site 22) was the third highest for the period of record since 1939. The highest discharge for the period of record also was recorded at Trout Creek near Sulphur Springs (1,830 ft3/s, site 24). USGS field crews observed Trout Creek overflowing the road at State Highway 581 (fig. 4). At Cypress Creek near San Antonio, a discharge of 923 ft3/s was recorded (site 25), the highest since 1987 and the second highest for the period of record. Farther downstream at Cypress Creek at Worthington Gardens, a record discharge of 1,800 ft3/s

was recorded (site 26). A peak discharge of 1,820 ft3/s was computed at Cypress Creek near Sulphur Springs (site 27), which was the highest since 1960 and second highest for the period of record. A period of record discharge of 205 ft3/s also occurred at Curiosity Creek at 122nd Avenue near Sulphur Springs (site 28). Downtown Tampa also experienced flooding from the Hillsborough River and storm surge from Tampa Bay (fig. 5). The Hillsborough River at Platt Street (site 29) near the mouth of Hillsborough River at Tampa Bay experienced a storm surge nearly 4 ft above the normal high tide gage reading of 11.94 ft. The peak recorded gage height of 15.83 ft was the highest for the period of record (fig. 6).

Streams in other watersheds also had peak flows. At Anclote River near Elfers (site 30), a peak discharge of 2,680 ft3/s was the second highest computed since the period of record peak in 1960. A peak discharge of 945 ft3/s at Pithlachascotee River near New Port Richey (site 31), was the highest since the 1997-1998 El Niño.
