Abstract: The Central and Southern (C&SF) Florida Project for flood control (known as flood risk management now) and other purposes is authorized by Section 203 of the Flood Control Act of 1948, Public Law (PL) 80-858, and modified by Section 203 of the Flood Control Act of 1968, PL 90-483. Current water management operations in the project area are governed by the System Operation Manual (SOM) Volume 4, for the Water Conservation Areas (WCAs), Everglades National Park (ENP), and ENP to South Dade Conveyance System (SDCS) approved 28 August 2020, hereafter in this document referred to as the 2020 Combined Operational Plan (COP) Water Control Plan (WCP) (USACE 2020). The associated COP Environmental Impact Statement (EIS) is incorporated by reference. The C&SF Project was authorized and currently functions as a multi-purpose water management system. The Congressionally authorized purposes of the C&SF Project include flood control (now referred to as “flood risk management”), navigation, water supply, recreation, and enhancement of fish and wildlife, drainage and water control, groundwater recharge, preservation of Everglades National Park, and prevention of saltwater intrusion. Operations in the project area are governed by the COP WCP. The U.S. Army Corps of Engineers (Corps), Jacksonville District, in response to a request from the Miccosukee Tribe of Indians (MTI), South Florida Water Management District (SFWMD), Florida Fish and Wildlife Conservation Commission (FWC), among other stakeholders, is evaluating a deviation from the COP WCP to reduce water levels in WCA-3A to address impacts identified by the MTI to tribal tree islands and cultural resources. The COP WCP (Appendix A section 7.5.3 of the EIS) states that the Chairman of the MTI can make recommendations to the Corps to change operations if the MTI determines conditions indicate jeopardy to the health or safety of the MTI. Appendix A section 7.10 also documents that occasional deviations may be necessary and requested to avoid or reduce negative impacts related to water management operations. These deviations require USACE, South Atlantic Division (SAD) approval, must follow ER 1110-2-240, and must be consistent with the project authorization and be within existing authorities. The MTI provided correspondence that was received on October 11, 2023, with such a request (Appendix B). The SFWMD and FWC also provided correspondence between October 13 and October 16, 2023, requesting a deviation to protect natural resources. The following discussion provides more background on the need for the deviation.
