Water SuppliesWater Supplies
Water Quantity and Quality
• Development within watersheds• Water sources are affected from distant areas • Some hatcheries have seasonal fluctuations in
temperature and quantity• Influent water quality affects our effluent• Pass-by requirements: increased responsibility to y q p y
maintain creek flows and use less water in the hatcheries
PCB’s and Trout Production
• Commercial fish feeds may contain PCB’s – Within FDA limits for animal feedsWithin FDA limits for animal feeds
• Hatchery trout are sampled annuallyAre within the 1 meal/week consumption limit– Are within the 1 meal/week consumption limit

• Higher PCB concentration in lower raceway trout
• Closed the lower raceway series (2002)• Hatchery renovations include by passing• Hatchery renovations include by-passing
hatchery water around the old lower raceway seriesraceway series.
Permit Issues
• NPDES Permits• Past: basic ppm limits TSS D O CBOD etcPast: basic ppm limits TSS, D.O., CBOD, etc.
– Settling Ponds & ClarifiersNo : ppm limits and TMDL (po nds / ear)• Now: ppm limits and TMDL (pounds /year)– Microscreen filters & Recirculation Systems
• Noncompliance => reduced production

Trout Production Goals
• Meet NPDES effluent limits • Produce 11 inch troutProduce 11 inch trout• 1.9 million pounds = 3.3 million trout
R d “ l ” fi h• Reduce “surplus” fish• Reduce flows and solids where possible• Increase efficiency and reduce costs
Future Trout Production Issues
• Water quality and availability• Increased effluent regulationsIncreased effluent regulations• Cost containment to produce trout
M i i i l f ili i• Maintaining complex facilities• Training Managers and Culturists
