We are just finishing up a significant project at the junction of Lower Wrangler and the bottom of North Fork. At that location, the stream (North Fork) entered a culvert, ran underneath Wrangler and popped out on the skiers' right side of Wrangler. Over the years that culvert had rusted, degraded, and collapsed and was ready to be replaced. Our initial plan was to replace that culvert, but as we looked closer and closer at the project, we realized we could, simply, return the stream to a more natural setting. Planning and construction tasks included project design, removing the old culvert steel, regrading the area to a more natural stream channel, lining the channel with local rock and re-vegging the area with native plants. The project involved a lot of people including members from the A-Basin team, Forest Service staff, a civil engineer, a hydrologist, an ecologist, a local excavation contractor and Xcel Energy (of course the stream crossed a powerline). The earthwork is done, the stream is running down the rehabilitated channel and we are entering the re-veg stage. Over the next couple weeks, we will be planting wetland species and that process will continue again next summer.
I think it will be fun to watch the regrowth here and see a more natural stream return over the coming years.
