Perennial Lakes and Sinkholes
A Primary Zone of 35' applies to all perennial lakes that are 2 acres or larger in size, and to sinkholes that maintain perennial surface waters. This Zone is measured from the lake or sinkhole, beginning at the break in slope at the top of the shoreline, out to the designated width. In addition, a Secondary Zone may apply to these waterbodies depending on the SSC associated with the harvest unit (Table 2). The Secondary Zone, if required, would begin at the outer boundary of the Primary Zone and continue outward from the lake or sinkhole the specified distance (See Appendix 1).

Intermittent Lakes and Sinkholes
A Stringer and a Secondary Zone of at least 35 feet apply to all intermittent lakes that are 2 acres or larger in size and to sinkholes that maintain intermittent surface waters (Figure 3). Depending on the SSC associated with the project site, the Secondary Zone could extend out as much as 300 feet (Appendix 1)

OFW, ONRW and Class I Waters

Outstanding Florida Waters (OFWs) and Outstanding National Resources Waters (ONRWs) are waterbodies that have been identified as having unique and/or exceptional values and therefore are afforded extra protection from potential sources of pollution. Class I Waters are those that have been designated as a drinking water supply and are also afforded extra water quality protection. For these reasons, a 200 foot Primary Zone applies to all OFWs, ONRWs and Class I Waters, regardless of the type or size of the waterbody. A list and location of these waterbodies is provided in Appendix 4.
