Deep Creek Gully Watershed Management Plan

Persistent roadway and yard flooding, coupled with occasional structural flooding led residents in this watershed to organize a local stormwater committee to lobby for stormwater infrastructure improvements to the DeSoto County area.  DRMP provided a comprehensive surface water model to better understand the drainage of the area, update FEMA mapping and provide improved flood protection.

Deep Creek Gully is a tributary of the Peace River, located in the southwest corner of DeSoto County.  The watershed is approximately 12-square miles in size including residential developments, golf courses, pastures, agricultural, mining, wetlands and natural ground.  Modeling challenges in this watershed included high water table conditions with flat topography leading to uncontrolled flow with complex interactions between numerous manmade drainage systems and natural areas. The project involved updating a previous watershed model conducted by DRMP to comply with current Southwest Florida Water Management District Watershed Management Program standards. 

DRMP developed a 100-year floodplain for use in updating FEMA flood insurance rate maps. A comprehensive surface water model was also developed to improve flood protection for area residents and businesses.
