Detailed Description

Permanent Site: D1 East Transect; Depth: 1.5 Meters (5 Feet); Distance from river mouth: 0.2 Kilometers (0.1 Miles); Pre/Post Dam Removal: 2 years post-dam removal; Lat/Long: 48.15115998,-123.56734404; Site Description: This site is right off the mouth of the river and is actively being buried. This was the last year the site could be scuba surveyed. The depth on this transect went from a little over 30 feet to less than 5 feet at its easternmost end. Substrate is almost all clean sand with a small patch of gravel towards the end of the transect. All species of seaweeds are gone and no invertebrates were present. Schools of Pacific sand lance (Ammodytes hexapterus) were at the site. Individual sand lance can be seen rapidly darting out of the sand at 0:35 and 0:36 seconds. A small starry flounder (Platichthys stellatus), a species which feeds on sand lance, appears at 1:41 seconds.
