• Client: Southwest Florida Water Management District

• Preparation of inundation maps for four fail scenarios
• Computer modeling of dam breach
• Investigation of major bridge crossings and residential development down stream
• Identification of potential dam failure mechanisms

The Medard Reservoir Dam is a 7,000 foot long, 35 foot high, earth-filled embankment located in eastern Hillsborough County, Florida with a surface area of approximately 740 acres and a storage capacity of over 13,000 acre-feet. Due to downstream development, the dam is classified as "high hazard."

In preparation for the development of a comprehensive Emergency Action Plan, Kisinger Campo & Associates Corp. completed a dam breach and flood routing analysis for the Medard Reservoir Dam. The first phase was a "sunny day" breach analysis that considered two failure scenarios, a piping failure at the primary spillway and an overtopping failure of the secondary spillway. SWFWMD also requested a second phase to include "wet weather" conditions for both scenarios.

The study resulted in a report documenting the analysis. Of particular importance to SWFWMD were the inundation maps that provide the basis for the Emergency Action Plan.
