Flooding in Southwest Florida, August 25-30, 2017
Heavy rainfall from a tropical wave (92L) caused moderate to major flooding in southwest Florida. The rainfall began on August 25 and lasted until August 28, totaling 17 inches in the Bradenton area and 18 inches in the Ft. Myers area. USGS staff made 60 discharge measurements through August 30.
USGS streamflow gages recorded period of record peaks at 11 stations. In the Ft. Myers area, the resulting flood at Tenmile Canal near Estero, Florida, was the highest in the 20-year period of record. In Punta Gorda, Florida, the flow at Shell Creek was the second highest in 45 years of record, with a chance of recurring between 10 – 25 percent (1 chance in 10-25 for any given year).
In Florida the USGS maintains a network of more than 500 stream gages that provide data in real time. Data from these gages are used by local, state, and federal officials for numerous purposes, including ensuring public safety and for flood forecasting by the National Weather Service.
