Columbia Basin Trout Hatchery near Moses Lake, Washington, produces Rainbow Trout for the recreational fishery. Declining available water has forced the hatchery to consider reducing production. Redd Zone designed three Water Spikes to match the water flows and modest head pressure to hyper oxygenate three of the raceways. The manager expects to add more to his complex to fully utilize available rearing potential based on the positive results from this phase of the project.
