Notes:
Crabtree Creek is a large perennial stream that flows through a valley which has BKFW: 30'
been confined due to development. Recent rainfall has left the creek high and BKFD: 10,
turbid, obscuring channel features and biology. Crabtree Creek is known to WW: 20-25'
support various fish populations. WD: 4-6'
Substrate: S, Gr, R, B
Clarity: Turbid
Flow: Fast

Notes:
House Creek is a large perennial channel that parallels Blue Ridge Road BKFW: 15-20'
through much of the corridor. House Creek is relatively shallow through much of BKFD: 2'
the reach and the substrate is composed of large cobbles and rocks. House WW: 12'
Creek appears to flood frequently upstream of the Blue Ridge Road crossing. WD: 6"
Substrate: S, Gr, C, R
Clarity: Clear
Flow: Fast
