In accordance with Section 7-11 of the ACF Master Water Control Manual and the Jim Woodruff Lock and Dam and Lake Seminole Water Control Manual (Appendix A) dated March 2017, a 7-foot navigation channel will be supported via water releases on the ACF during the months of January through May when the composite storage for the system is in Zones 1 and 2.
