Samish Island

The north side of Samish Island is a great place to talk about human impacts to beaches and we've been bringing the CTP class, and other groups, here for years. Bulkheads, bluff modifications, and groins. Sediment supplies have been heavily impacted (some material still comes from farther northwest) and what sediment that's left is heavily compartmentalized by two large projecting fills that act as groins. The spit (Samish Beach) at the distal end has undergone a variety of changes over the decades and was most recently the site of a large (by Puget Sound standards) private gravel nourishment project.
