Johns Lake Minimum Levels

Johns Lake is approximately 2,500 acres and provides a regionally important recreational resource, with good sport fishing, county parks and access for canoeing, kayaking and other watersports. There are also large intact wetland communities on the south and east portions of the lake that provide habitat for numerous wading birds and other fish and wildlife.

The District’s MFLs approach involves two separate but interrelated components: 1) MFLs Determination; and 2) MFLs Assessment. The first involves determining a minimum hydrologic regime necessary to protect relevant water resource values. The second involves comparing this MFLs condition to a current-pumping condition to determine the current status of the MFLs. The overall process involves an analysis of ecological, recreational, and hydrological information, all of which undergo independent scientific peer review. Field work and surface water modeling for the Johns Lake are ongoing. The Johns Lake MFLs determination is scheduled for completion by the end of 2023.

MFLs Peer Review Approach in the CFWI

The District typically engages in voluntary peer review of all MFLs on its Priority List. Because Johns Lake (Orange and Lake Counties) is within the Central Florida Water Initiative (CFWI) area, the District will follow the CFWI MFLs peer review process. This includes stakeholder input in the selection of MFLs report and model peer reviewers as well as stakeholder involvement in public workshops for the review of the models, hydrological analyses and environmental analyses that are used to determine and evaluate proposed MFLs within the CFWI.

As with other CFWI MFLs, the Johns Lake MFLs peer review is divided into two phases. First, the surface water model, including calibration and long-term simulations, will be reviewed by independent technical experts in the field of hydrologic modeling. The second phase of the peer review process will involve an evaluation of recommended minimum lake levels, including the environmental criteria used for MFLs determination and the hydrologic analyses used for MFLs assessment. One or more firms will be selected for review of the MFLs determination and assessment.
