Online MFL meeting, Santa Fe, Ichetucknee, and Springs 2020-06-16

Online, so you don’t have to travel, you can ask why SRWMD is proposing reductions in the minimum flows of the Santa Fe and Ichetucknee Rivers:


In Lower Santa Fe and Ichetucknee Minimum Flow and Minimum Water Level (MFL) Frequently Asked Questions (FAQs),

What is the new, proposed MFL?

A minimum flow and minimum water level (MFL) evaluation was used to determine the quantity of water needed to ensure the safety and health of the Lower Santa Fe and Ichetucknee (LSFI) Rivers and associated springs. The new LSFI MFL evaluation has determined that median Santa Fe River flows should be 91.9%near Ft. White and 91% near US Hwy 441 gaging stations, and that median Ichetucknee River flows should be 97.2% at the US Hwy 27 gaging station.To review the 2019 LSFI Technical Document, visit the LSFI webpage.

How does the new, proposed MFL differ from the 2015 LSFI MFL evaluation?

The existing and proposed MFL evaluations have determined that similar amounts of water are needed to preserve the environmental health of these ecosystems and prevent significant harm from water withdrawals(pumping). This consistency in findings supports the validity and outcome of the previous 2015 MFL evaluation.

The new MFL evaluation utilizes the best available science and data including the use of the North Florida Southeast Georgia (NFSEG) groundwater model. An additional gaging station along the Lower Santa Fe River (near US HWY 441) was utilized to account for the unique river characteristics of that section of the river and to better assess the status of the river.

Will the new LSFI MFL impact the Seven Springs permit recommendation differently than the current/old LSFI MFL?

The issuance of water use permits is governed by state/District rules and state statutes. The total water available for consumptive use under the new MFL evaluation is consistent with the current/old MFL. Until an assessment has been conducted for the new LSFI MFL rule, it is unknown how any permit request and staffrecommendation would be impacted. District staff follow a lengthy and strenuous evaluation for consumptive use permit requests. For more information regarding the permit process, visit

Thanks to Merrillee Malwitz-Jipson for the heads-up.
