structures that are connected to land and extend into the lake.

(parallel to shore) than cross-shore currents (perpendicular to
shore).  Groins are commonly straight, linear structures, but
they can have various shapes including a “T” or “L” shape. Newer
groins are typically constructed with armor stone, concrete
blocks or concrete modules. Older gr
