The Farmers Screen for Fish Hatcheries

The Farmers Screen can greatly reduce hatchery O&M costs for water diversions from rivers or streams that supply fresh water to hatchery ponds. A great example of this kind of application is the installation at the Oregon Department of Fish and Wildlife’s Oxbow Fish Hatchery on Herman Creek, a tributary to the Columbia River.

Hatcheries

Hatcheries must maintain consistent flows to their facilities at all times.  Often, hatchery diversions are located on higher gradient systems with sediment and organic debris issues which can make operating a fish screen difficult.  The Farmers Screen is a solution specifically designed for diversions located in higher gradient systems.  The unique horizontal design minimizes operation and maintenance requirements and provides consistent flows while meeting state and federal fish protection guidelines.
