SE managed five different contracts and collaborated with over a dozen agencies and other stakeholders over the course of five years to see through the removal of Horse Creek Dam on a tributary to the Wild and Scenic Sisquoc River. Here’s the dam in its final moment as the primer cord and explosives go off. Steelhead trout and other native aquatic species now have access to over 19 miles of habitat upstream of this former migration barrier.
