30.91L.010 Lake.

"Lake" means a body of freshwater that:

(1) Occurs in a depression of land or expanded part of a stream, including reservoirs;

(2) Is greater than 6.6 feet (2 meters) in depth at the deepest point at ordinary low water;

(3) Has less than 30% coverage by trees, shrubs, or persistent emergent vegetation; and

(4) Has an ocean-derived salinity of less than 0.5 parts per thousand (ppt).

A lake is bounded by the ordinary high water mark, or, where a stream enters the lake, the extension of the elevation of the lake’s ordinary high water mark within the stream. Lakes formed by a dam on a stream or river are bounded by a contour approximating the normal spillway elevation or normal pool elevation.

Lakes do not include artificial water bodies including, but not limited to, lakes constructed for irrigation or detention, wastewater treatment facilities, farm ponds, recreational or fishing ponds or other landscape ponds, unless they contain naturally occurring salmonids. Naturally occurring means that the salmonids have migrated into the lake via a connection to another water body containing salmonids and are not artificially introduced into the lake.
