Width2.6 meters
Water AppearanceClear
OdorNone
Attachment Sites 19/20Well-developed riffle and run; riffle is as wide as stream and length extends 2 times the width of the stream; cobble predominate; boulders and gravel common.
Embeddedness18/20Fine sediment surrounds and fills in 0-25% of the living spaces around and in between the gravel, cobble, and boulders.
Shelter For Fish19/20Snags, submerged logs, undercut banks, cobble and large rocks, or other stable habitat are found in over 50% of the site.
Channel Alteration13/20Some stream straightening, dredging, artificial embankments or dams present, usually in areas of bridge abutments; no evidence of recent channel alteration activity.
Sediment Deposition19/20Little or no enlargement of islands or point bars and less than 5% of the bottom affected by sediment deposition.
Channel Flow Status19/20Water reaches base of both lower banks and minimal amount of channel substrate is exposed.
Bank Vegetative ProtectionLEFT:8/10; RIGHT:8/1070-90% of the streambank surfaces covered by natural vegetation, but one class of plants is not well-represented; some vegetative disruption evident; more than one-half of the potential plant stubble height remaining.
Condition of BanksLEFT:9/10; RIGHT:7/10LEFT:Banks stable; no evidence of erosion or bank failure; little potential for future problems. RIGHT:Moderately stable; infrequent, small areas of erosion mostly healed over.
