1.1 Habitat Type

Code	Description
PP	Pool at base of plunging cascade or falls
PT	Pool-like trench in the centre of the stream
PL	Pool scoured along a bank
PB	Pool separated from main flow off the side of the channel (large enough to offer refuge to small fishes). Includes sloughs (backwater with vegetation), and alcoves (a deeper area off a wide and shallow main channel).
PD	Pool formed by impoundment above dam or constriction
P	Pool (unspecified type)
GL	Water moving slowly, with a smooth, unbroken surface. Low turbulence.
RI	Water moving, with small ripples, waves and eddies-waves not broken, surface tension not broken. Sound: babbling, gurgling.
RA	Water movement rapid and turbulent, surface with intermittent white water with breaking waves. Sound: continuous rushing, but not as loud as cascade.
CA	Water movement rapid and very turbulent over steep channel bottom. Much of the water surface is broken in short, irregular plunges, mostly whitewater. Sound: roaring.
FA	Free falling water over a vertical or near vertical drop into plunge, water turbulent and white over high falls. Sound: splash to roar.
DR	No water in the channel or flow is submerged under the substrate.
