Cypress Creek Watershed Management Plan
Interflow recently completed the Cypress Creek Watershed Management Plan Update for Hillsborough County (it is currently in peer review). This project is cooperatively funded by the Southwest Florida Water Management District (SWFWMD). The hydrologic and hydraulic modeling was conducted in accordance with the SWFWMD Guidelines and Specifications (G&S).
The Cypress Creek watershed is approximately 160 square miles spanning across the central portion of Hillsborough and Pasco Counties. The model domain for this project is approximately 42 square miles with 33 square miles lying in Hillsborough County. Through extensive research of as built plans, ERP permit files, and field reconnaissance, Interflow developed a comprehensive Geographic Watershed Information System (GWIS) geodatabase containing over 750 subbasins and more than 1,075 primary links. The model simulations were completed using EPA SWMM 5.1. The updated Cypress Creek model has been successfully calibrated and verified to measured rainfall USGS streamflow gage data.
Interflow evaluated flood protection level of service and developed alternative projects for improving the flood protection and water quality functions of the watershed. Interflow is currently preparing a Project Development and Evaluation for one of the flooding areas of concern.
