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 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.
Former ODFW Oxbow Fish Hatchery manager Duane Banks described the difference the Farmers Screen made for their operations in the January/February 2010 issue of Hatchery International, saying:
“It was like night and day — actually quite a dramatic change with things being a lot less labor-intensive. During the first big rain storm after the install, I actually woke up a couple of times in the night because I thought our alarm systems must have been broken.”
