LakeMaster

LakeMaster is a brand of digital bathymetric maps for freshwater lakes. The maps provide high-resolution depth contours, shoreline features, and bottom structure to assist boating, fishing, and lake management. The underlying data are generated from sonar surveys, public bathymetric data, and contributed observations, then merged into standardized lakewide datasets.

Contemporary LakeMaster maps depict depth contours at multiple interval scales and often include shading to visualize slope. They typically highlight underwater features such as drop-offs, weed beds, and submerged structures, as well as man-made elements like boat ramps, docks, and marinas. Some products offer tools for adjusting for lake-level changes and for comparing data across different time periods, with compatibility for export to GIS software.

Distribution is usually via proprietary memory cards or digital downloads designed for use with compatible plotters and mapping systems. LakeMaster products are widely used by anglers, guides, and water-resource professionals, particularly in North America, and cover thousands of lakes with periodic updates intended to improve coverage and accuracy.

History and development notes suggest that LakeMaster emerged to provide consistent, high-detail lake-depth data across many lakes, produced by specialized hydrographic teams and mapping firms. Over time, the product line has evolved to incorporate additional data sources and to align with common charting standards used in recreational electronics.
