Renovation of Niagara Springs Steelhead Hatchery

1. Renovation of Niagara SpringsSteelhead Hatchery LSRCP Hatchery Production Meeting March 13, 2013

3. Project Goals • Create a larger indoor nursery environment for steelhead eggs and fry with natural photoperiod • Eliminate fish pathogens from influent spring water • Remove debris from influent and effluent spring water • Repair deteriorating concrete raceways • Replace bird control netting • Expand administrative workspace, shop and storage buildings

4. Phase 1 Construction 2012

5. Phase 2 Construction 2013

6. Site Design Priorities: • Retain gravity flow water source • Provide pathogen free water for incubation and indoor rearing • Install a vat size and quantity that allows an even distribution of fish when moved into outdoor raceways • Provide ability to rear fish indoors until they were large enough for marking Challenges with space for hatchery building: • Building requires a large footprint with little land available • Back wall of hatchery building supports the entrance road • Need to maintain access between raceways and hatchery building for fish tankers • Creating a vat room layout that included enough space for the vats while maintaining a clear separation of the two different stocks

7. Existing Indoor Rearing: Total number of vats = 21 Vat dimensions: 8’L x 2.5’W x 2.5’D Rearing volume per vat: 37.5 ft3 Max flow for incubation = ~ 3 cfs Max flow per vat = 47.6 gpm Max density index = 0.88 lbs/cf/in Max flow index = 0.70 lbs/gpm/in Approx. eggs/fry per vat = ~ 50,000 Split inventory – eggs & fry Size at transfer to outdoor raceways = 1,000 fpp

10. Indoor Rearing Design Criteria: • Total number of vats = 38 (16 OFH, 22 PFH) • Vat dimensions: 50’L x 4’W x 3.5’D • Rearing volume per vat : 552 ft3 • Max flow for incubation = 18 cfs • Max flow per vat = 212 gpm • Max density index = 0.35 lbs/cf/in • Max flow index = 0.85 lbs/gpm/in • Approx. eggs/fry per vat = ~ 55,000 • Entire inventory received as eyed eggs • Target size at transfer to outdoor raceways = 90 fpp (at marking)

12. Intake & Filter Building: • Water source → Niagara Springs middle pool via RVTC canal • Maintain gravity flow • No in-stream work (BRS) • Flow meters per IDWR requirements • Two sets of drum and disc filters for different size debris • 2 drum filters – 100 µm • 2 disk filters – 30 µm • Full 18 cfs can be passed through either set of filters without affecting operation • Filters and backwash spray system operated on timer or head differential

14. UV System: • Pathogens of concern: • Infectious Hematopoietic Necrosis (IHN) • Infectious Pancreatic Necrosis (IPN) • Furunculosis • Enteric Red Mouth (ERM) • Viral hemorrhagic septicemia (VHS) • Whirling Disease (WD) • Cold Water Disease (CWD) • Nucleospora salmonis • UV doses for inactivation of these pathogens → 5,000-150,000 mJ/cm2 • All but IPN inactivated at 40,000 mJ/cm2 or below • IPN requires system that is 3-4 times larger

15. UV System (continued)… • Design dose = 60,000 mJ/cm2 (minimum dose at end of lamp life) • Total of three UV vessels • 2 for operation, 1 backup • UV system alarming: • Lamp failure • Low dose • Generator backup for filter building and UV system

16. Alarming/SCADA

17. Vat Room • Size of vat room: • Old vat room = 1,340 ft2 • New vat room = 18,500 ft2 • Number of rearing vats: • Old vat room = 21 vats • New Vat room = 38 vats • Total rearing volume: • Old vats = 750 ft3 • New vats = 21,000 ft3 • Natural lighting

19. Additional Rooms • Feed Room • Storage of palletized feed • Workbench for weighing feed • Egg Room • Receive, enumerate and disinfect eyed eggs • Laboratory use • Boot Room • Vat room gear storage • Mud Room • Remove outdoor gear • Water fountain • Restroom • Visitor Room • View of vat room • Display tank • Information, brochures, etc. • Water fountain • Restroom

20. Administrative Area • Office • Manager’s office • 3 Workstations • Seasonal room • Conference Room • Break/lunch room • School tours • Meetings

21. Phase 2 • Raceway water intake modifications • Outdoor raceway modifications • Bulk feed storage modifications • Bird netting modifications • Install discharge traveling screens • Construct shop building • Construct storage building

22. Raceway Water Intake • Leaf debris during the spring and fall plugs head screens and tail screens on raceways • Can be unpredictable - frequent monitoring by staff during peak loads and stormy weather • Install stainless steel inclined traveling screens to remove most debris • Operate on automated schedule or head differential • Traveling screen openings the same as raceway screens

23. Raceway Modifications • Total of 19 raceways • 14 original from 1966, 5 additional in 1993-1994 modification • Repair or replace raceway walls (original 14 raceways) • Concrete cracking and spalling • Rusting and deterioration of keyways • Replace steel keyways in original 14 raceways with stainless steel keyways to address corrosion • Install additional keyways in all 19 raceways • Keyways currently at 100 foot intervals • Install additional stainless steel keyways at 50 foot intervals

24. Traveling Bridge Replacement • Split large traveling bridge into 2 smaller bridges • Reduce maintenance on bridges • Eliminate racking, derailing • Switch to more reliable direct drive power system • Allow for bird netting supports on raceway wall • Replace all feeders

25. Bulk Feed Storage • Raise height of bulk feed storage hoppers to allow personnel to perform maintenance more easily • Raise height of feed conveyor system to eliminate the risk of head injuries Bird Netting • Install support system on raceway wall to reduce sag • Replace existing 2-3” mesh bird netting with ¾” mesh netting

26. Discharge Traveling Screens • Issues with large mats of algae breaking loose and leaving ponds • NPDES concerns • Plugging RVTC screen • Two discharge points: Niagara Springs Creek and RVTC canal • Install stainless steel inclined traveling screens to remove debris • Similar design and operation to system at raceway intake

27. Shop Building • Mechanical room • Lab room • NPDES sampling equipment • Pathology • Storage bay with mezzanine • Vehicle Bay • Bigger shop area • 640 ft2 vs. 880 ft2 • Gear room • Store gear used in raceways • Restroom • Drinking fountain

28. Storage Building • Lawn equipment storage • Large center bay for 10-ft raceway screen storage • Other miscellaneous storage • Covered, fenced outdoor storage area • Bulk fuel storage

29. Project Summary Address Operational Constraints • Enlarge incubation and early rearing for improved fish health • Reduce maintenance and repair costs • Improve predator control • Enlarge office workspace Incorporate Modern Fish Culture Technology • Water filtration and UV disinfection • Improve bio-security • State-of-the art alarming and standby power • Debris removal screening
