Permanent Site: K1 West Transect; Depth: 6.1 Meters (20.0 Feet); Distance from river mouth: 4.5 Kilometers (2.8 Miles) east; Pre/Post Dam Removal: 3 years post-dam removal; Lat/Long: 48.13592923,-123.51082988; Site Description: This is a shallow site. Sediment is a gravel/sand mixture. This video includes footage from surveys conducted both on August 4 (0:04-0:51 seconds) and September 18 (0:52-2:20seconds). During the first survey, the majority of the seaweeds seen were reds (0:25, 0:32 seconds) with some brown seaweed, mainly the perennial seaweed Pterygophora californica (0:27 seconds) and Saccharina spp. (0:10, 0:22 seconds). However, on September 19, late summer growth of seaweed was observed. Red and brown seaweed was very abundant. Four species of browns were recorded including Alaria marginata (2:18 seconds), acid kelp Desmarestia (1:27, 2:11 seconds), Saccharina spp. (1:31 seconds) and the perennial seaweed Pterygophora californica (1:58, 2:16 seconds). Small Dungeness crabs Metacarcinus magister (1:25, 1:45 seconds) were common on both surveys.
