Lake Basin Littoral Zone – 15-Foot Standard

This data layer from the Minnesota Department of Natural Resources displays the 15-Foot Standard Lake Basin Littoral Zone. This depth contour shows all lake areas 0-15 feet in depth and was calculate by DNR Fisheries. Lake basin littoral zones have historically been calculated based on the maximum depth of light penetration. See the Lake Basin Littoral Zone - Observed layer for the actual recorded depth of light penetration, which varies due to water clarity.
