*** NEUMANN KMR-81 HYPER-CARDIOID MICROPHONES ***

0:46:19 GENERAL HANGING AROUND

0:46:50 JULIAN RHINEHART .. DESCRIBING .. MODEL OF GENERATION UNIT IF YOU LOOK TO LEFT YOU WILL SEE AN ARROW INDICATING FLOW OF WATER FROM A 30-FOOT PENSTOCK (OR PIPE) .. FLOWS IN HORIZONTAL FASHION INTO A SCROLL CASE WHICH HOLDS A WATER WHEEL (SOMETIMES CALLED A TURBINE RUNNER) .. FORCING W.W. TO ROTATE IN A HORIZONTAL FASHION AND AS WATER FLOWS THROUGH WATER WHEEL THROUGH THE VENTS IT WILL GO IN A DOWNWARD PATH OUT INTO THE TAIL RACE WHICH IS THE AREA IMMEDIATELY DOWNSTREAM OF THE DAM. IN THE PROCESS ENERGY IS TRANSFERRED FROM THE FALLING WATER TO THIS ROTATING SHAFT WHICH TURNS A GENERATOR THREE LEVELS UP IN THE POWER PLANT

0:48:00 THE WATER DISCHARGED INTO THE TAIL RACE BEGINS ITS PATH TO SOUTHERN CALIFORNIA.. AND TO MEXICO ..

0:48:40 AMBIENCE IN THE OUTER ROOM

0:51:15 I'M JULIAN RHINENART REGIONAL PUBLIC AFFAIRS OFFICER FOR BUREAU OF RECLAMATION IN BOULDER CITY NEVADA .. WHAT LOOKING AT? WE ARE LOOKING AT TOPO MAP OF RIVER

0:51:55 HOW DOES WATER GET TO S. CAL? PRIMARY PURPOSE OF DAM .. TO CONTROL THE RIVER .. W/OUT HOOVER THE OTHER SMALLER DAMS ON THE RIVER WOULD NOT HAVE BEEN POSSIBLE ... ALSO PROVIDES STORAGE .. LAKE MEAD IS LARGEST MAN-MADE RESERVOIR IN U.S. 110 MILES IN LENGTH ..

0:54:50 AND DOWN HERE IS PARKER? THAT'S RIGHT .. WE OPERATE LOWER PORTION OF COLORADO RIVER ON A

DOWNSTREAM REQUIREMENTS BASIS .. WATER SO SCARCE IN THIS PART OF COUNTRY THAT WE RELEASE FROM HOOVER DAM ONLY ENOUGH WATER TO MEET DOWNSTREAM WATER REQUIREMENTS ON WEEKLY MONTHLY YEARLY BASIS .. THEY FIGURE OUT WHAT THEY NEED .. WE RELEASE ON THAT BASIS ..

0:53:35 EXPLAIN AGAIN WHAT THE PROCESS IS? HOOVER IS FIRST MAJOR CONTROL POINT ON RIVER .. FINISHED IN 1935 .. 67 MILES DOWNSTREAM IS DAVIS DAM COMPLETED IN 1953 .. 155 MILES DOWNSTREAM IS PARKER .. THIS IS A DIVERSION DAM. IT WAS CONSTRUCTED WITH FUNDS ADVANCED FROM THE METROPOLITAN WATER DISTRICT OF SOUTHERN CALIFORNIA, BUILT BY BUREAU OF RECLAMATION FOR THE PURPOSE OF DIVERTING WATER INTO SOUTHERN CALIFORNIA .. LAKE HAVASU IS THE INTAKE POINT.

0:54:20 METROPOLITAN HAS CONSTRUCTED A PUMPING PLANT AT LAKE HAVASU ON THE CALIFORNIA SIDE OF THE RIVER THAT LIFTS WATER INITIALLY SLIGHTLY OVER 1600 FEET AND THE WATER BEGINS A 242 MILE TRIP THAT ENDS IN LAKE MATTHEW IN SOUTHERN CAL.
SO WE ARE LOOKING AT A SCALE MODEL OF A PUMPING PLANT ? THAT'S CORRECT AND INITIALLY YOU HAVE A VERY SUBSTANTIAL LIFT IN THERE .. WATER 20 MILES TO THE WEST WILL COME OUT IN AN OPEN CANAL .. AND THE MAJORITY OF THE TRAVEL ACROSS THE DESERT IN AN OPEN CANAL .. SO WHERE WE ARE LOOKING AT COLORADO RIVER AQUEDUCT ..
THAT GOES ALL THE WAY OVER TO A POINT WHERE IT IS DIVERTED TO L.A. OR SAN DIEGO? YES IT GOES TO A TERMINUS RESERVOIR CALLED LAKE MATTHEWS AND FROM THERE IT GOES TO VARIOUS WATER AGENCIES .. INC. SAN DIEGO
(GARY ASKS HIM TO DO BRIEFER VERSION)

0:56:00 THIS IS A TOPO MAP OF LOWER COLORADO RIVER VALLEY .. FIRST STRUCTURE IS HOOVER .. THEN DAVIS .. HOOVER STORES THE WATER ... DAVIS IS REGULATORY .. GIVES US FLEXIBILITY .. 155 MILES DOWNSTREAM IS PARKER DAM ... (THIS IS WHERE HE MISSPOKE .. SAYING PARKER IS HIGHEST DAM) --IT IS AN INTAKE POINT FOR METRO WATER ETC.

0:57:05 WHAT ROLE DOES HOOVER PLAY IN GETTING WATER TO CAL.? PROVIDES FLOOD CONTROL PROTECTION ETC. SMALLER DAM COULDN'T EXIST WITHOUT HOOVER ..

0:57:35 THESE DAMS MADE SOUTHERN CAL. POSSIBLE? ****THEY CERTAINLY ACCELERATED THE DEVELOPMENT OF SOUTHERN CAL. --THERE IS NO QUESTION ABOUT THAT. HOOVER DAM PROBABLY MADE THE DEVELOPMENT OF THE SOUTHWEST AS WE KNOW IT TODAY, POSSIBLE. IT WOULD HAVE OCCURRED EVENTUALLY BUT NOT IN THE SAME TIME ..

0:58:05 ****WHAT DID DAM REPRESENT? ****IT WAS A HIGH POINT IN ENGINEERING TECHNOLOGY. THERE WERE OVER 1000 ENGINEERING FIRSTS. ETC. --HOOVER DAM REPRESENTS AN EARLIER ERA .. A DIFFERENT ERA .. ONE DIFFERENT FROM THE ONE WE HAVE TODAY.
WHY IS IT DIFFERENT? IF YOU LOOK CAREFULLY AT THIS MAP YOU WILL SEE THAT ALL THE GOOD DAM SITES HAVE BEEN TAKEN AND BY AND LARGE THE INFRASTRUCTURE FOR OUR WATER DELIVERY SYSTEM FOR THIS PART OF THE COUNTRY IS COMPLETED. RIGHT NOW OUT FOCUS IS NOT ON CONSTRUCTION .. IT'S ON MANAGING THE WATER ... MAKING THE VERY BEST USE OF THE WATER WE HAVE AVAILABLE TODAY.

0:58:50 ***SO YOU WON'T BE BUILDING MORE DAM?

***WE WON'T BE BUILDING ANY MORE HOOVER DAMS .. THAT'S CORRECT ...

OR PARKER?

MAYBE ON SMALLER SCALE .. BUT FOR MOST PART, DAMS LIKE HOOVER, DAVIS AND PARKER WILL NOT BE REPEATED.

0:59:20 AMBIENCE .. HOOVER MAP ROOM

*** NEUMANN RSM-190 MICROPHONE ***

1:01:00 AMBIENCE -¬ OUTSIDE DAM -¬ JAPANESE VOICES AND BUMPS

1:02:15 TO OUR IMMEDIATE RIGHT .. NEW FACILITIES UNDER CONSTRUCTION .. DOWN STREAM, WE'RE LOOKING, UH, THE DAM IS 726 FEET HIGH SIX HUNDRED AND SIXTY FEET THICK AT THE BASE, NEARLY AS THICK AS IT IS HIGH.

NOW THE RIVER IS COMING?

THE RIVER IS BEING DIVERTED THROUGH POWER PLANT .. IMMEDIATELY DOWNSTREAM OF THE DAM, WHAT WE CALL THE TAIL RACE, YOU WILL SEE ROILING WATER THAT IS A GENERATOR DISCHARGING WATER BACK INTO THE RIVER SYSTEM TO BEGIN ITS TRIP DOWNSTREAM. WE ARE LOOKING AT THE ARIZONA POWER PLANT. IT HAS NINE GENERATORS IN IT -¬ACROSS THE RIVER THE NEVADA POWER PLANT HAS 8 GENERATION UNITS.

IS THIS WHAT RIVER WOULD HAVE LOOKED LIKE BEFORE THE DAM WAS HERE?? THIS WOULD BE A REPRESENTATIVE PICTURE OF RIVER AT CERTAIN TIMES OF YEAR. IT WAS RIVER OF TOO MUCH OR TOO LITTLE .. FLOODING VERSUS NONE AT ALL.

1:03:45 WHEN YOU RELEASE WATER .. WHERE DOES IT COME OUT?

ALL OF IT IS ROUTED THROUGH THE POWER PLANT FOR GENERATION OF POWER .. THEY GENERATE MORE THAN ENOUGH TO OPERATE HALF MILLION HOMES. WATER ENTERS THROUGH INTAKE TOWERS .. INTAKE IS 100 TO 200 FEET BELOW THE SURFACE OF WATER TODAY .. AND IS CARRIED DOWN TO POWER PLANT THROUGH SERIES OF PIPES REFERRED TO AS PENSTOCKS .. THESE PIPES ARE THIRTY FEET IN DIAMETER .. EACH PENSTOCK WOULD FEED UP TO FOUR GENERATION UNITS.

1:04:30 HOW LONG DID IT TAKE TO BUILD?

****THIS IS THE GRANDDADDY OF THE BIG DAMS .. NO BOOKS TO REFER TO .. NOBODY TO GET ANSWER FROM .. THEY DID LOT OF PIONEERING. THEY CONSTRUCTED THIS DAM FROM '31 TO '35 .. IT WAS COMPLETED AHEAD OF SCHEDULE AND UNDER BUDGET .. TWO PHRASES YOU DON'T HEAR MUCH ANYMORE.

THIS WAS COMPLETED DURING DEPRESSION .. HOW DID PEOPLE REACT?

IT WAS A REAL SALVATION FOR MANY FAMILIES. WE HAD PEOPLE LINED UP WHO WERE LIVING IN SHANTIES WAITING FOR EMPLOYMENT. AT ITS PEAK IT EMPLOYED MORE THAN 5 THOUSAND PEOPLE AT ONE TIME .. ALTOGETHER ABOUT 16 THOUSAND PEOPLE WERE ON THE PAYROLL ..

****WHAT DID IT MEAN TO THE DEVELOPMENT OF THE WEST?

THE COMPLETION OF THIS DAM MADE THE DEVELOPMENT OF THE SOUTHWEST AS WE KNOW IT TODAY POSSIBLE .. THIS WOULD HAVE OCCURRED BUT NOT AT THE PACE THAT IT HAS ..

1:06:35 AMBIENCE .. A TOURIST'S VOICE, A DAD, YELLS AT KID --"NO, NO I WILL HOLD YOU UP .. YOU WANT TO SEE HOW HIGH IT IS ... THERE WON'T BE ENOUGH LEFT OF YOU TO PUT THROUGH A RITZ CRACKER!"

1:07:39 "WHY DO THEY BUILD IT HIGH?" "WHY?" "SO I CAN'T SEE IT?"

1:08:00 AMBIENCE --GENERAL TOURIST AND ROAD AND TRUCKS

1:08:30 "YOU'RE NOT CLIMBING UP THERE ...."

1:09:20 LET'S GET AWAY FROM THE CAUCASIANS

1:09:45 AMBIENCE --TRAFFIC GOING OVER THE DAM --PLANE GOES OVER --SOME BEEPS AND THINGS IN DISTANCE

1:11:45 THIS IS THE UPSTREAM SIDE OF DAM .. WE ARE ON WALKWAY TO ONE OF FOUR INTAKE TOWERS .. THESE ARE INTAKE TOWERS GOING THROUGH WATER PLANT AND NORMALLY WE RUN ALL THE WATER RELEASED THROUGH HOOVER DAM THROUGH OUR POWER PLANT.

HOW IS INTAKE OCCURRING? I DO NOT SEE ANYTHING HAPPENING OUT THERE? WE ARE ACTUALLY ONLY LOOKING AT TOP OF TOWERS .. ACTUAL INTAKE POINT IS 100 FEET BELOW SURFACE OF WATER .. TAKES WATER IN THROUGH PENSTOCKS THIRTY FEET IN DIAMETER

PRESUMABLY THERE'S A STRONG CURRENT?

SEVERAL HUNDRED FEET BELOW ..

WHEN YOU SAY IT'S RELEASED AS NEEDED, EXPLAIN? WE GET ORDERS, RELEASE AS NEEDED NO MORE .. WE GENERATE POWER IN THE PROCESS OF RELEASING WATER BUT WE DO NOT RELEASE WATER FOR HYDRO POWER.

1:14:20 WHAT IS WATER USED FOR? IN SOUTHWEST, 85 PERCENT FOR AG. --REST GOES TO CITIES. THIS IS ONE SOURCE OF WATER FOR NEARLY 25 MILLION PEOPLE USE THE WATER .. THAT INCLUDES POPULATIONS OF LAS VEGAS, L.A., SAN DIEGO, PHOENIX AND TUCSON

SO EVEN THOUGH 85% TO AG, ALL THOSE CITIES GET WATER FROM HERE?

THEY RECEIVE A PORTION OF THEIR WATER .. TWO THIRDS OF WATER USED IN SOUTHERN CAL. COMES FROM COLORADO RIVER ..

IT WOULDN'T BE POSSIBLE WITHOUT THIS STRUCTURE?

WITHOUT SOME STRUCTURE TO CONTROL RIVER AND TO STORE WATER ..

WELL LET'S GO DOWN INTO IT ..

1:17:50 WHAT ARE WE LOOKING AT? YOU ARE LOOKING AT VALVE HOUSES ON EACH CANYON WALL ABOVE POWER PLANT .. SIX ROUND OPENINGS. WHEN DAM WAS COMPLETED THERE WAS NOTHING UPSTREAM TO CONTROL RIVER. THEY HAD TO PLAN FOR FLOW AS HIGH AS ONE HALF MILLION CUBIC FEET PER SECOND. WE HAVE SPILLWAYS ON SIDE CAPABLE OF HANDLING 200 HUNDRED CUBIC FEET EACH PER SECOND. ALSO CAN PUT SOME THROUGH THE NEEDLE VALVES. WITH COMPLETION OF UPSTREAM DAMS. THE VALVES ARE NOT NECESSARY AND WE HAVE REMOVED FOUR TO CUT MAINTENANCE COSTS ..

I DON'T UNDERSTAND .. EXPLAIN?

WELL AS I MENTIONED THIS WAS A PIONEER DAM THEY HAD TO DO SOME ESTIMATING .. THEY DESIGNED THIS DAM TO HANDLE MORE THAN NECESSARY .. WITH UPSTREAM DAMS PROVIDING CONTROL .. THIS CAPACITY IS NOT NECESSARY

WHY DID COLORADO HAVE SUCH A FLOODING PROBLEM .. THIS IS DESERT .. WHAT CREATES FLOOD SITUATION?

IF YOU REALIZE THAT THE WATER YOU ARE LOOKING AT TODAY IS ROCKY MOUNTAIN SNOW MELT I THINK THE ANSWER IS QUITE EVIDENT .. VERY LITTLE OF THAT WATER IS HERE BECAUSE OF RAIN.. WHEN YOU HAVE LARGE YEARS OF SNOWPACK AND SNOW MELT --IT IS MORE EASILY UNDERSTOOD .. PRACTICALLY ALL THE WATER YOU SEE IS SNOW MELT ..

HE GOES ON TO EXPLAIN IN MORE DETAIL HOW NEEDLE VALVES WORK ...

1:23:00 BUY YOUR TICKETS AND STAY IN LINE

1:23:20 HOOVER DAM ELEVATOR .. TOUR TAPE --DETAILS ON ELEVATOR SPEED --MILES OF GALLERIES --YOU'LL BE IN THE INTERIOR OF THE DAM --WATCH YOUR STEP --BUZZ ON TAPE --OUT OF ELEVATOR

1:25:40 TALKS ABOUT WHERE WE ARE --IN DAM INTERIOR

1:26:05 SOUND OF TOUR GROUP COMING TOWARDS US --CONTINUES TO MOVE BY TEENAGE VOICES

1:27:15 WHEN YOU WERE LOOKING DOWN YOU SAW POWER PLANT ON EACH SIDE .. AND CONNECTING BUILDING .. WE JUST WALKED OUT OF CONNECTING BUILDING AND ARE ENTERING THE ARIZONA POWER PLANT .. (AMBIENCE CHANGES UNDER THIS)

1:27:25 L.N. WHAT ARE THESE HUGE ... ?
J.R. THE RED (?) STRUCTURES ON THE POWER PLANT FLOOR ARE THE ACTUAL GENERATION UNITS .. OF NINE GENERATORS, 8 ARE IN OPERATION TODAY.

DIMENSIONS?

I DON'T HAVE EXACT FIGURE ..

HOW MANY GENERATORS?

NINE ON ARIZONA SIDE, EIGHT IN NEVADA .. EXPLAINS WHY DIFFERENT ..

WHERE DOES POWER GO .. ARIZONA?

SOURCE OF POWER FOR NEVADA, ARIZONA AND CAL ... MAJORITY GOES TO SOUTHERN CAL.

WHAT PERCENT OF SO. CAL. POWER COMES FROM HERE?

MUCH SMALLER THAN IT USED TO. IN WWII THIS POWER PLANT PROVIDED 85 PERCENT OF POWER NEEDED FOR DEFENSE OF SOUTHERN CAL. --LESS THAN 5 PERCENT OF LAS VEGAS POWER COMES FROM THIS PLANT ..

1:30:40 LEO INCRIMINATES HIMSELF --GARY BECOMES AN ACCOMPLICE

1:30:55 AMBIENCE --HOOVER DAM GENERATORS ... SOUNDS PRETTY GENERIC, A CONSTANT HUM

1:33:00 WE'RE GOING TO THE THREE LEVELS BELOW THIS ONE --SOUND OF WALKING --HUMS AND FOOTSTEPS AND A FEW VOICES

1:34:10 AMBIENCE --ENTERING GENERATOR LEVEL --MORE HUM

1:34:50 **** LN. WHAT IS THIS HUGE WHEEL LIKE STRUCTURE?

THIS IS A TURBINE RUNNER .. A LOT OF PEOPLE WOULD CALL IT A WATER WHEEL. THIS IS THE OBJECT THAT CATCHES THE FORCE, THE ENERGY OF THE FALLING WATER, TRANSMITS IT TO THE SHAFT WHICH TURNS THE GENERATION UNIT AND GENERATES THE POWER ..

SO THIS WOULD NORMALLY BE IN THE WATER?

THIS WOULD BE WITHIN A TURBINE UNIT .. THREE LEVELS BELOW US. LOCATED IN A SCROLL CASE. (THIS PARTICULAR UNIT IS HERE FOR MAINTENANCE.) AND THE WATER WOULD COME IN FROM THE SITES GENERATING A HORIZONTAL FORCE THAT WOULD FORCE IT TO ROTATE AND THEN IT WOULD EXIT THROUGH THE BOTTOM

L.N. WHAT'S THIS CONSTANT HUM?

J.R. THE NOISE COMES FROM TWO SOURCES: ROAR OF WATER GOING THROUGH PENSTOCKS .. AND THE GENERATORS THEMSELVES ..

G.C. DO THEY EVER WEAR OUT?

J.R. YES THEY DO .. EXPLAINS HOW THEY ARE MADE, MATERIAL AND DESIGN ..NEW AND IMPROVED .. A LONGER LIFE

WONDERMENT ABOUT THE CLICKING SOUND

1:39:05 RHYTHMIC CLICKING BEGINS .. QUIETLY AT FIRST -¬ 1:39:20 .. RHYTHMIC CLICKING GETS LOUDER -¬MORE LIKE SQUEAKING

1:41:25 CLICKING OR SQUEAKING WHEEL FROM A DISTANCE

1:45:15 LEO: I LOVE TO BLOW UP THIS JOINT

1:43:25 J.R. TAKES US TO A TYPICAL UNIT .. AMBIENCE -¬ GENERAL TURBINE SOUND

1:45:10 L.N ... WHAT DOES THIS SAY?

J.R... THAT'S WHAT I WAS TRYING TO DO .. (LONG PAUSE) .. THIS IS ONE OF OUR LARGER 127 THOUSAND KILOWATT GENERATORS .. AND ON SIGN IT SAYS CAUTION: PLEASE READ INSTRUCTIONS

GARY ASKS HIM TO RE-DO:

1:46:15 THIS IS ONE OF OUR LARGER UNITS .. THE TURBINE WAS MANUFACTURED BY G.E ... IT IS INTERESTING TO NOTE .. WARNING .. CAUTION: READ INSTRUCTIONS ..MANUAL IS IN THE CONTROL HOUSE

LEO ASKS ABOUT GAUGES .. J.R. SAYS THEY WERE ORIGINAL -¬ MANY HAVE BEEN OUTDATED

1:49:35 L.N. WHEN YOU WALK AROUND THIS DAM .. WHAT DO YOU FEEL WHAT IS OUR SENSE OF PRIDE?

J.R. OH THERE'S A TREMENDOUS FEELING OF PRIDE AND ACCOMPLISHMENT WHEN YOU RECOGNIZE WHAT WAS ACCOMPLISHED HERE AND THE CONDITIONS UNDER WHICH THEY ACHIEVED THEM ALSO EACH DAY I LEARN SOMETHING NEW ..

L.N. DOES THIS DAM REPRESENT THE PAST?

1:50:25 ****THIS DAM WAS THE HIGH POINT OF ITS ERA WHICH WAS THE CONSTRUCTION AND THE DEVELOPMENT ERA. IT WAS CONSTRUCTED AT A TIME ...
IT WAS A CIVIL ENGINEERING ACHIEVEMENT. BUT TODAY WE ARE IN A DIFFERENT ERA .. BECAUSE THE INFRASTRUCTURE, THAT SYSTEM WHICH DELIVERS THE WATER .. FOR ALL PRACTICAL PURPOSES HAS BEEN CONSTRUCTED... SO THE JOB NOW IS NOT TO BUILD MORE -¬IT'S TO MAKE USE OF WHAT'S THERE.

1:51:30 ****L.N. SO THIS IS THE PAST IN TERMS OF WATER?

****J.R. WE'RE ENTERING INTO A NEW ERA. IT'S DIFFICULT TO IMAGINE THAT WE COULD CONSTRUCT A NEW HOOVER DAM TODAY .. THE ENVIRONMENTAL, THE ECONOMIC CONSTRAINTS.

L.N. WHAT DO YOU FEEL ABOUT THAT PASSING OF AN ERA?

J.R. I THINK MOST OF RECOGNIZE THAT FACILITY HAS SERVED US WELL. THAT IN FUTURE IT WILL CONTINUE TO IN A DIFFERENT ROLE .. SUPPLYING POWER ETC.

1:51:50 ****L.N. WHERE DO YOU GO FROM HERE?

J.R. WHAT WE DO NOW IS TO START TO LIVE WITHIN OUR MEANS. TO MAKE THE BEST USE WE CAN OF THE WATER RESOURCES THAT ARE AVAILABLE TO US TODAY IN A WISE MANNER WITH WATER CONSERVATION FIRST, RECOGNIZING THAT IT COULD BE VERY DIFFICULT TO DEVELOP ADDITIONAL RESOURCES ..

L.N. DOES EVERYONE AGREE?

J.R. BASICALLY HE SAYS YES

1:52:55 L.N. WHAT PRICE WAS PAID ENVIRONMENTALLY FOR HOOVER DAM?

J.R. YOU HAVE A RESERVOIR, A CHANGE IN RIVER, CHANGE IN SPECIES OF FISH .. CHANGES WHICH CAME ABOUT FROM CONSTRUCTION OF DAM .. THESE ARE THE TRADEOFFS ..

1:53:55 GARY TRIES TO GET HIM TO SAY SOMETHING INTERESTING .. BUT HE STEADFASTLY REFUSES

1:54:50 J.R. BEFORE THE NOISE BUILDS UP ... THIS IS WHAT WE REFER TO AS THE SHAFT GALLERY .. IT IS THE SAME NINE GENERATORS .. TWO LEVELS BELOW .. THIS GALLERY CONTAINS THE SHAFTS WHICH CONNECTS THE GENERATORS ABOVE WITH THE TURBINE RUNNERS (WATER WHEELS) BELOW. AND IN THIS GALLERY ARE THE MECHANISMS FOR CONTROLLING THESE UNITS .. WICKET GATES TO SHUT UNITS DOWN .. AND YOU WILL ALSO SEE THE VALVES THAT ISSUE THE WATER, RELEASE THE WATER INTO THE GENERATION UNIT, THEY WILL BE BELOW US, SO AS WE ENTER INTO HERE YOU WILL HEAR A LOUD ROAR, A COMBINATION OF POWER PLANT ABOVE AND THE TURBINES BELOW

1:56:05 AMBIENCE ... OPENING DOOR .. LOUD ROAR-¬ -¬THIS PRETTY COOL SOUND .. WITH CREAKING DOOR OPENING UP SOMETHING INTO ROAR --OCCASIONAL GAUGE NOISES OR SOMETHING
