The Bathymetric Maps layer is a spatial layer that enables users to visually determine which lakes have existing bathymetric maps. These lakes are ones which have had a (typically hand-drafted) hardcopy bathymetric map created for them. These maps have then been scanned and are presented in this layer as PDF files which are linked to the FWA polygon for the corresponding lake. URLs in the attribute table allow the user to link to these source bathymetric maps through their Internet Browser.

This layer is different from the Bathymetric Maps of Surveyed Lakes layer WHSE_FISH.BATH_LAKE_BATHYMETRIC_SP in that each lake in the Bathymetric Maps of Surveyed Lakes layer has been digitized and georeferenced and has intelligent contour polygons created for it.
