Detailed Description

Permanent Site: C2 West Transect; Depth: 16.8 Meters (Feet 55.1); Distance from river mouth: 0.7 Kilometers (0.5 Miles); Pre/Post Dam Removal: 2 years post-dam removal; Lat/Long: 48.147841,-123.57663268; Site Description: One of our deepest sites. Substrate is all muddy sand. Seaweed is absent. Featherduster tubeworms, mainly Eudistylia vancouveri (1:13, 1:29, 1:40 seconds) and Schizobranchia insignis (0:21 seconds), are still abundant in contrast to the east transect. Lots of woody debris is present (0:10, 1:10, 1:19, 1:28 seconds). Geoduck clams Panopea generosa (0:19 seconds) are common. They have likely always been there but it is easier observe their siphons (large, oval indentations) in a muddy sand substrate.
