(2) Operators shall protect riparian management areas extending: (a) 100 feet from the high water level of large lakes; and (b) 50 feet from the high water level of other lakes that have fish use or other lakes that are equal to or greater than one-half acre in size. (c) No riparian management area is required for other lakes that do not have fish and that are less than one-half acre. (3) For all lakes with riparian management areas, operators shall provide the following to the riparian management areas and the aquatic areas: (a) Live tree retention (OAR 629-650-0010); (b) Soil and hydrologic function protection (OAR 629-650-0020); (c) Understory vegetation retention (OAR 629-650-0030); and (d) Snag and down wood retention (OAR 629-650-0040). (4) For all lakes not having riparian management areas, the lakes shall be protected as other wetlands (OAR 629-655-0000).
