Fish Passage
A falls blocks anadromy at river mile 1.2 (Washington Department of Fisheries 1975). A culvert at RM 0.3 on stream 14.0002 is a complete barrier (Northwest Indian Fisheries Commission 2002). This culvert is scheduled for replacement in 2003 (Winecka 2002, personal communication). Several impassable culverts are present upstream of the falls on Perry Creek, where coastal cutthroat are presumed to be present (Northwest Indian Fisheries Commission 2002). See Map 12. Fish passage was rated poor.

Riparian Buffers
Riparian vegetation has been removed along the lower mile of Perry Creek where numerous homes have been built (Fraser 2002, personal communication). Schuett-Hames et al. (1996) measured canopy closure on five reaches of Perry Creek and one tributary. Canopy closure on the lower mile of stream was 47%, below the target value of 86% necessary to maintain Class A water quality temperature standards. Canopy closure above RM 1 ranged from 84% to 93%. Mean canopy closure on the four reaches upstream was 90%, greater than the mean target value of 76% necessary to maintain Class A water quality temperature standards. Canopy closure on stream 14.0002 was 97%, greater than the target value of 82% needed to maintain Class A water quality temperature standards (Schuett-Hames et al. 1996). Riparian condition was a data gap. Riparian canopy closure was rated good to poor.

Streambank Condition
Unconsolidated sediments deposited by glaciers have the potential to contribute a large amount of fine and coarse sediment to Perry Creek. These sediments erode easily. Bank erosion was noted along the stream reach adjacent to State Route 8 (Washington State Department of Natural Resources and Simpson Timber Company 1995). Some portions of the lower mile of stream have been channelized to protect homes (Fraser 2002, personal communication). Streambank condition was rated fair to poor.

Large Woody Debris
Schuett-Hames et al. (1996) reported a range of 0.798 to 4.202 pieces of large woody debris per channel width on the mainstem. The weighted mean (by stream reach length) was 1.7 pieces per channel width. Unnamed tributary 14.0002 had 1.445 pieces of woody debris per channel width. Although LWD was relatively abundant, key pieces were rare. Abundance ranged from 0.000 to 0.132 pieces per channel width. The mean (weighted by stream reach length) was 0.049 pieces per channel width. Total large woody debris abundance was rated good to poor, while key piece abundance was rated poor.

Pool Frequency
Pool frequency on the mainstem ranged from 2.98 to 10.35 channel widths per pool. Pools occurred at a mean frequency (weighted by stream reach length) of 4.67 channel widths per pool on the mainstem. Pools were uncommon on tributary 14.0002 with a spacing of 44.12 channel widths per pool (Schuett-Hames et al. 1996). Pool frequency was rated fair to poor.

Pool Quality
Mean residual pool depth (weighted by stream reach length) was 0.46 meters (1.51 feet) on Perry Creek. Pool surface area ranged from 25.2% to 82.1% on the mainstem. Weighted mean pool surface area was 47.7% on the mainstem. Pool quality was rated good to poor.
