St. Johns River Water Management District proposed amendments to Fla. Admin. Code Ann. r. 40C-8.031, Minimum Surface Water Levels and Flows and Groundwater Levels. The proposed amendments would establish minimum water levels for Lake Grandin in Putnam County and Lakes Colby and Shaw and Three Island Lake in Volusia County; add a duration and return interval to the established minimum water levels for Lake Ashby in Volusia County and Lake Gore in Flagler County and delete their listed hydroperiod categories; make minor technical changes by rounding to the nearest decimal place for the minimum average levels for Lake Broward in Putnam County and Lake Sand Hill in Clay County; make minor technical changes by changing the name of the hydroperiod category from §temporarily flooded§ to §seasonally flooded§ for the frequent high levels for Bird Pond, McKasel, and Pam Lakes in Putnam County and Mills Lake in Seminole County; make a minor technical change by changing the name of the hydroperiod category from §seasonally flooded§ to §temporarily flooded§ for Lake Sunset in Lake County; make minor technical changes by changing the name of the hydroperiod category from §typically flooded§ to §typically saturated§ for the minimum average water level of Daugharty and Dias Lakes in Volusia County, Disston Lake in Flagler County, and Echo Lake in Putnam County; and revise the formatting of existing subsections for clarity. https://www.flrules.org/Faw/FAWDocuments/FAWVOLUMEFOLDERS2009/3541/3541doc.pdf pp. 5131-45.
