| Objectives | The discharge of treated flow-through process wastewater to the San Joaquin River. The hatchery is located approximately 20 miles northeast of Fresno. The hatchery is a cold-water flow-through facility that includes an intake structure at the Friant Dam; incubator trays; eight trout rearing ponds each 600 feet long, broodstock ponds and a spawning house; aeration capability, and five settling ponds and a constructed wetlands area to treat the full flow of the facility. The facility also includes eight redwood tanks for additional growing space and special experiments; food storage facilities; public restrooms; chemical storage facilities; six homes; and septic system with a 110 foot by 150 foot leach field. With construction of the leach field, the Facility discontinued the use of two domestic wastewater ponds. Discharges of domestic wastewater are not authorized by the Order. Discharge of treated flow-through process water from the hatchery activities to the San Joaquin River occurs at Discharge Outfall 001, approximately 36 deg. 59 min. and 50 sec S latitude and 119 deg. 43 min. and 08 sec.
