Trout Unlimited project managers wear many hats. From idea to implementation, we shepherd on-the-ground projects every step of the way and gather input from all the involved parties. These opinions (like nymphs in your fly box) can vary widely.
Our job is to strike a balance that will benefit trout and satisfy the partners involved. When working on private land the most important partner is the landowner. If the project is a fish screen, for instance, the landowners are the people who will spend the most time interacting with the final product.

They also have the most to lose if the project impedes their water delivery system. For these reasons, they get a seat at the table during project design while we select the appropriate screen type. We discuss many aspects of the project before determining the appropriate style. These include, but are not limited to:
- Location (how protected will it be?)
- Size (how much water needs to pass through it?)
- Land use constraints (how does it fit into the landscape?)
After reaching consensus on these issues and others, we can select the most appropriate screen type.
On Trout Creek, near Cody, Wyoming, a self-propelled rotating drum screen was chosen because the site was protected due to its distance from the stream, the irrigation canal was small, and the site constraints were minimal (drum screens require more square footage than some other types of screens).

The Trout Creek project is important because it protects trout (including some native Yellowstone cutthroat trout) that have left the North Fork of the Shoshone to spawn.The screen prevents those spawning cutthroat and their offspring from ending up in the middle of a field instead of back in the mainstem of the Shoshone. These fish then have access to hundreds of miles of public water.
