The steepest, most powerful section of the wave next to the white water, where the push is strongest and where riders want to stay.
Pocket 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 Pocket 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 Pocket 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
The pocket is the curved, steepest part of the wave located just in front of the breaking white water. It is the power zone and the most critical place to be: this is where the wave's energy concentrates and where the push that holds a rope-free rider is greatest. Riders constantly adjust fore and aft to stay in the pocket. Drift too far forward and you fall off the front into the flats; drift too far back and you sink into the white wash. Boat setup that lengthens the pocket gives riders a longer, more forgiving zone to work in.
