2 Fish Protection at the Red Bluff Diversion Dam s Emergency Pumping Plant 2014 International Conference on Engineering & Ecohydrology for Fish Passage Madison, WI - June 9-11, 2014 Darryl Hayes, P.E.

3 Background of RBDD Outline Emergency Pumping Plant and Fish Screen Design Construction Challenges Performance Testing RBDD Removal in 2014 Lessons Learned

4 Original Red Bluff Diversion Dam s Purpose: Gravity divert water into the Tehama-Colusa and Corning Canals (140 miles total length); Irrigate 150,000 acres (producing $250 million of crops annually) Provide adult fish passage around facility while gates are in place; Prevent fish entrainment of downstream migrating juvenile fish with canal fish screen

5 History of RBDD Operations 1964 Red Bluff Diversion Dam built; gates in year-round 1986: Annual period of dam operations reduced 1994: Annual operations limited to May 15 to Sept. 15; Sacramento River winterrun Chinook salmon listed as endangered 1995: U.S. Bureau of Reclamation builds research pumping plant to test fishprotecting technology 1998: Sacramento River winter-run steelhead listed as threatened 2002: Draft environmental documents on pumping-plant alternative to dam released 2006: Green sturgeon listed as threatened in Sacramento River; bureau releases revised environmental documents improving fish passage and irrigation water supply 2008: Dam operations come under jurisdiction of federal court; final environmental documents released; pumping plant alternative selected; 2009: Red Bluff lawsuit settled; dam operations shortened to June 15 to Aug. 31; first construction contract awarded for New Intake and Emergency Pumping Plant 2012: Gates out on June 1 for good! 2014: All original RBDD Facilities removed or decommissioned

6 RBDD Passage Issues Adult Fish Poor fish ladder performance - poor attraction flows, delays, etc. Ladders not designed for sturgeon or other native fish species Juvenile Fish Delayed passage through lake and under gates Pedation and injury below gate area Fish screen bypass issues concentration of fish

7 Red Bluff Diversion Dam Facilities New On-River Flat Plate Screen and PP (2500 cfs) Canal Drum Screens (2500 cfs) Original Louver Screen Facility (2500 cfs) Gravity Canal Intake Area Temporary Fish Ladder PP (135 cfs Flat Plate Screen) Research PP (385 cfs Hidrostal, Archimedes and screen bypass) Emergency PP (500 cfs Cone Screens)

8 Emergency Pumping Plant and Fish Screen Challenges Aggressive schedule required to meet TCCA deliveries Design, Fabricate, and Construct from Jan-Mar cfs capacity needed to supplement RPP and IPP 1500 square feet of screen area needed for fish protection Only 3 feet water depth available Less than 150 feet of waterfront available Backwater area (mostly) Pumps must operate with 15+ ft. of river fluctuation Design must not undermine existing facilities or operations Facility must be removed at end of operations

41 Operational Conditions and Challenges

42 Sweeping Velocity up to 10 fps at Upstream Screen

43 and near Zero fps at Downstream Screens Gravel accumulation after 2 years at base of downstream screens due to poor sweeping flows

44 Brush arms were additionally weighted and prevented from lifting from velocity and gravel buildup

45 Velocity Measurements and Video Monitoring Study by NMFS, USFWS, and DFG

46 Poor Velocity Distribution in Upstream Screen Units

47 Approach Velocity Detail of Upstream Two Units

48 Lesson - Alternative Baffle Testing Conducted by USBR in 2010

49 Internal Screen Flow Baffle and Divider Plates Separate Flow and Prevent Flow-Through

50 Internal Pie baffle prevented flow through and improved velocity distribution

51 New Facility Operational June 2012 Emergency PP no longer needed

52 Facility Demolition June 2014
