During the dry season, water levels in the Lower Hillsborough River have been dropping low enough to significantly increase salinity levels resulting in negative impacts on estuarine conditions, and ongoing public concern. In the past, Morris Bridge Sink has been used as an emergency water supply source and has now been identified as a key component of Southwest Florida’s plan for greater augmentation and recovery efforts. ADA has been tasked with establishing baseline conditions and continued monitoring of water levels, wetland vegetation and bathymetry, soil subsidence, and biological parameters in and around Morris Bridge Sink. Evaluating the potential impacts of pumping on wetlands near the sink is a key component of the consumptive use permit. Quarterly reports are submitted to the District and a report is presented to DEP annually.
