[Editor’s Note: In 2011, Orvis offered financial support for an important project, run by the Trout Unlimited Home Rivers Initiative, to help restore habitat in the mountains of Idaho. Here’s a wrap-up of the work from project manager Matt Woodard.]
This recent project is geared toward restoring fish passage and eliminating entrainment (washing of sediment into the water) in the outgoing diversion ditches on both Diamond and Lanes Creeks, which come together to form the Blackfoot River.
This past field season we completely rebuilt both the Diamond and Lanes Creeks diversions using a system of instream rock weirs to elevate the water surface for irrigation purposes, while providing full fish passage. Additionally, we built new head gate control structures that provide more precise control over water that is diverted, combined with new fish screen structures that will keep the fish from entering the outgoing ditch and the creek.

The fish screens were built winter 2013 and will be available for installation during spring or summer 2013, when ground and weather conditions permit.
These two projects will open approximately 25 miles of new spawning and rearing habitat that was previously blocked by the old diversion barriers. This will make a significant difference in bolstering and recovering future Yellowstone cutthroat trout populations in the Blackfoot River and its headwaters.

this will offer great trout habitat.
