This scenatio is likely due to vegetation clogging which causes the structure flow to be falsely high. - If there is positive head accross the structure, negative flows will not be used - USACE can force the preferred flows to be one gage or the other, overwriting the above rules (exception is if the gates are closed, then flow will be zero) POC for questions about this report: Savannah Lacy, 904-627-0501, Savannah.H.Lacy@usace.army.mil Report Generated 12MAY2021 @ 06:15 ** Preliminary Data - Subject to Revision **
