This Farmers Screen project addresses the following issues:

This Farmers Screen helped to open 6.1 stream miles for safe fish passage and serves over 3,600 acres of farm land.

The Badger Creek screening and passage project is located within the Badger Creek Wilderness Area. This was considered a high priority project for ODFW, the USFS, and the Wasco County SWCD because it was blocking passage to 6.10 miles of high quality habitat in the wilderness area, as well as entraining Redband Rainbow Trout.

The project involved the creation of an upgraded diversion structure that could withstand high flow events; design and install of an upstream fish passage structure; and design and installation of a modular Farmers Screen. This system that can handle a wide range of flows (5 – 30 CFS). All of the components had to be pre-fabricated in segments that could be transported to the construction site via three miles of irrigation canal perched on a very steep slope.

This new Farmers Screen serves approximately 3,610 acres of farm land and helped to open 6.10 stream miles for safe fish passage.

The new systems consists of:

  • Two 4-section modular Farmers Screens configured as a dual screen with aluminum isolation gates
  • Updated fish return flume design
  • Removable steel diversion stanchions
  • Modular vertical slot fish passage structure (fish ladder)
  • Removable training wall
  • Gate on return pipe to eliminate backwater during shutdown periods
  • Re-installation of an existing Parshall Flume


Flowing through the Badger Creek Wilderness, Badger Creek is a high gradient tributary to the White River. This system has a reservoir as a source of flow that provides some late season flow stability but can also be a flashy system from the fall through the spring.

This diversion was previously unscreened and consisted of a stream-spanning concrete diversion and head gate structure. The project improved the diversion structure while using the existing head gate and head wall to create fish passage through a vertical slot fish way.  Aquatic Contracting installed the Farmers Screen system, as well as the fish ladder, behind the existing head gate and the screen system was able to fit within the existing ditch profile.

Project partners chose the Farmers Screen for this site over other screen options because it enabled construction without large amounts of concrete, the fact that power is not necessary for operation, and the reduced overall operation and maintenance requirements.
