Hemlock Dam Removal Video

In 2009 work began to remove Hemlock dam from Trout Creek, an important tributary of the Wind River. The dam built in the 1930s as a part of the new deal by the Citizen Conservation Corps has long been a migration obstacle for both upstream adults and outmigrating juveniles. The dam did feature a fish ladder, rare for dams of its era but the construction of the ladder did not readily facilitate upstream passage. Now, with the dam removed fish can easily access the upper 15 miles of the creek and the downstream reaches of trout creek are able to naturally recruit wood and sediment. Check out this short documentary film about the project with some excellent detail of how the project was implemented and some great before and after shots. With Condit Dam on the white salmon scheduled for removal as early as this fall the Lower Columbia has become a hotspot for dam removal projects
