perennial streams may also be identified using other methods. See p. 35 of manual.
Notes:
Stream S1, also known as Pigeon House Branch, is an urbanized perennial
stream that has incised and degraded banks, stong baseflow and good
substrate sorting. Stream geomorphology is somewhat impacted by erosion
occurring on the banks. No biology was observed in stream S1.
