Determination of the ordinary high water line (OHWL) has been and continues to be an important issue for the State of Florida and elsewhere. The OHWL defines the separation of sovereignty lands of the State and private ownership on non-tidal water bodies. We used imagery from multiple sources to determine if: (1) the water's edge can be detected around the lake margins and (2) vegetation community shifts can be reliably detected and correlated with OHWL. It was determined that in areas where water is known to be under vegetation canopy or in heavily vegetated marsh there were no distinct indicators of the OHWL on any of the remote sensing images used. This is because overhanging vegetation and emergent macrophytes both obscure the water's edge. We also found that vegetation types varied widely and none appeared to be precise indicators of the OHWL Most of the plant species in the vicinity of the known location of the OHWL were not classified in any one wetland designation and many were found both in wetland and upland areas and, therefore, provided no distinct characteristics that could be consistently identified or mapped in ArcView using remote sensing images.
