White wash
The foamy, broken, turbulent part of the wake behind the clean face; riders try to stay ahead of it in the clean pocket.
White wash is a term from limnology — the scientific study of inland waters. The detailed explanation below covers the definition, why the concept matters to lake water-quality interpretation, and how it intersects with the LakeGrade rubric. Reading White wash alongside the LakeGrade rubric helps make the rubric's structure intuitive — each grading parameter maps directly onto an established limnological concept.
The per-lake pages on LakeQuality always show the specific White wash value for that lake, so you can move from the general concept to the specific lake without leaving the site.
What It Means for Your Lake
White wash (also called the wash or white water) is the aerated, broken foam that tumbles behind the wake's clean curling face. It marks the back edge of the rideable wave. A good wakesurf wave has a clean section ahead of the wash; if a rider drops too far back they sink into the white wash and lose the push. Boat setup, particularly the use of a wake shaper, aims to clean up the wash so it doesn't crumble into the pocket and foul the wave.
