Objectives The facility discharges treated process wastewater from trout hatchery and rearing operations to the Merced River, waters of the State and the United States. The facility has a production goal of approximately 400, 000 pounds annually. Flow entering the facility from the Merced River is diverted into two streams-one to 16 concrete rearing ponds and one to hatchery operations and 10 raceways. All flow is directed to seven settling ponds, where it is treated by a minimum of two ponds. From the ponds, treated flow-through process wastewater is discharged to the Merced River at discharge Outfall 001.
