Consider the creation of “streamside management zones” (SMZ), whose widths are directly dependent on SMZ slope and stream class. Stream classes are defined as: • Class 1 stream segments: Support fish, or do not support fish but flow at least 6 months of the year, and contribute surface flow to another stream, lake, reservoir or pond covering an area greater than 0.1 acre. • Class 2 stream segments: Do not support fish, but contribute flow to another stream, lake, reservoir or pond covering at least 0.1 acre; and flow for less than 6 months; or do not contribute surface flow to another stream, lake reservoir or pond, but do flow at least 6 months of the year. • Class 3 stream segments: Have no fish, rarely contribute surface flow to another body of water and normally do not flow more than 6 months of the year.
