This data represents LiDAR-derived breaklines (1-foot) for the City of Fond du Lac in Fond du Lac County, Wisconsin in 2009. Hydro breaklines maintain the definition of water-related features in an elevation model. They are used to capture linear discontinuities in the surface, lake shorelines, single-line drains for small rivers, and double-line drains for large rivers. This data is available in both SHP and DWG formats.
