Fish Passage Program under the Fish and Wildlife Service contributed approximately $250,000 along with funds from partners totaling $2.1 million, and in the summer of 2009, action finally took place: the pump house was removed, the creek was diverted, Hemlock dam was dismantled, the creek channel was reconstructed, invasive weeds were removed, and riparian habitat was enhanced with native shrubs and trees.
Today, one year later, you can see the benefits of the dam removal project. Most notably, Hemlock Lake is no longer there! In its place is a meandering creek channel, with small trees planted on the banks that were previously under water. It will take time for the trees and brush to fill in, but in the meantime, the restored section of Trout Creek has likely been recolonized with lotic aquatic insects for fish to eat, sediment that had built up behind the dam over the years has been removed, and temperatures are no longer near the lethal limit for fish. Additionally, removing this barrier has opened upstream habitat for spawning and migrating steelhead.

With this improvement to Trout Creek, I'm looking forward to seeing how the habitat changes in the project area in the years to come. Be sure to take a look at the Forest Service's website about the project - it even has a video of an adult steelhead that moved up through the project area just hours after flow was restored through the creek bed! The video also shows a tractor moving large woody debris into the floodplain of the stream to enhance fish habitat...word gets out fast among the fish, it appears!
