---|---|
dsCurrentRef | Time Period of Content date indicates the date which the user can be confident of accuracy and completeness of the dataset. Littoral zone estimates are derived from existing Lake Bathymetry products (i.e., DEMs and contour lines: 15-foot contour for Standard Littoral Zone and contour of observed maximum depth of vegetation for Observed Littoral Zone). Lake bathymetric contour lines and DEMs are derived from existing lake contour maps of variable dates. (See Quick Layers:Hydrography:Lake Bathymetric Outline for field work dates of individual lakes.) Values for maximum depth of vegetation come from transect observations recorded during individual Lake Surveys (various dates). Vegetation depth values (when they exist) were used to estimate the Observed Littoral Zone. |

dsPurpose | This data was developed to assist in resource management and research applications by furthering the basic understanding of the littoral zone of a lake. Littoral area has implications for available habitat, spawning sites, productivity, oxygen levels, and erosion/sedimentation dynamics. |
