The Streamside Management Zone (SMZ) is an area or strip of land adjacent to
a stream or other body of water where management practices are designed to
p rotect water quality, aquatic wildlife and wildlife habitat. Trees and vegetation
within the SMZ act as a natural filter to keep sediment out of streams, re d u c e
soil erosion and act as a buffer to protect the stream from degradation caused
by nearby activities. The SMZ is n o t a zone of exclusion where silvicultural
activities are not permitted. Because of the need to protect water quality and
other important values, the SMZ is an area where silvicultural activities should
be closely and carefully managed.

C l a s s i fication cate g o ries used in dete rmining SMZ locations are :
Class I St re a m
S t reams or other bodies of water used for domestic water supply and/or
the spawning, rearing, and migration of fish, including impacted stre a m s
with recovery potential for a fishery. Also included are perennial streams that
contribute significant flow to downstream fisheries. The width of the SMZ for
a Class I Stream is measured from the Ordinary High Water Mark on each
side of the stream.
