Lake boards: permits and timing, season by season

Who holds the permits. For chemical treatment of the lake: DEP usually issues the permit to the person who owns or manages the property, not to the person who applies the product. For docks and walls built by members: each project needs its own state authorization as well as the association's approval. Docks, piers, walls and fill in or touching any pond or lake are regulated 'water obstructions'.
