Dr. Hubert Lienhard,
Chairman of the Boardof Voith Siemens Hydro
Power Generation

Dear readers, dear friends,
The fact that the entire world needs
energy for growth is undebatable.
Over the past few months, however,this debate is yielding some interesting new arguments. We aretrying to increase energy efficiency,
but also energy production. At thesame time, energy generation must
not increase pollution. A combination that is close to impossible.
For this very reason, each andevery form of energy generationmust be evaluated for the benefits
and impacts they have in eachindividual situation. Each country
should balance its energy mix,
based upon what makes the best
sense in terms of economics, importpolicies, energy independence, useof domestic resources, etc.
What sounds simple very often is ahighly complex and sometimes hard
to solve issue.

September 2006 I 14 I HyPowerAs an equipment supplier for thehydroelectric industry, we still can
do only one thing: promote hydropower as part of a multi-purpose
solution that provides clean, emission-free generation, irrigation,
drinking water supply and recreation. And, last but not least, theability to store energy, in terms ofpumped storage technology.
Pumped storage technology not
only makes sense for clean, economical peaking power, but later inthis edition of HyPower, you will findout what it has to do with soccer,
too! We are a leader in this technology and are proud to be chosen forthe latest European developmentsin pumped storage plants, especially in Austria right now.

Hydro again is threatened withthe burden of carbon charges eventhough it is an emissions free generator. This “playing” ground of
discussions, compared to otherfuels’ prices and emissions is simply
bizarre.
Therefore, we remain aligned with
the IHA to work through this politicalprocess and try to make our stand.
We see hydro as the best option, tostand through this test!
Whatever your ideas and thoughts
may be, I will be pleased to receive
them at
Hubert.Lienhard@vs-hydro.com.

Kind regards from

In contrast to the many advantages
that hydro power provides for developing and industrialized countries,
political decisions concerning hydropower are obscure, especially in theframework of Kyoto mechanisms
and IPCC work.

World Cup 2006: The soccer players are in top form and so
are the fans. But the cheering and nail-biting are not only
going on in the stadium. Throughout the world more than abillion soccer enthusiasts followed the event on TV and large
screens.
In the host country Germany alone,over 20 million TV sets were regularly turned on to the decisive knockout phase. However, the matches
are also intensively followed by theelectrical load changes on the control center screens of the pumped
storage power stations. What counts
here is when the ball stops rolling:blowing the whistle signals the startof peak output.
Half-time. Before the players even
get to the locker room, the fans are
already preparing to make the mostof the 15-minute break. That means
getting a drink from the fridge,
slipping a pizza into the oven andpaying a necessary visit. Electricity
consumption quickly reaches record
levels when millions of people are
all opening fridge doors, heatingovens and flushing toilets simultaneously.

The output of the base-load power
plants cannot satisfy this highdemand. Quick-reacting power
stations are needed to supply extra
energy into the grid. “When electricity consumption is high, that isduring peak load periods, we canrapidly produce a maximum output
of electricity”, says Dr. Klaus
Schneider, the Technical Directorof Schluchseewerk AG’s Wehr
Pumped Storage Power Station insouthern Germany. “In one sense,
pumped storage power stations are
the race horses of power plants,
plus they are so flexible they cantake on an emergency function for
the grid almost instantaneously.”
There is hardly an alternative to the
pumped storage power station in
extreme situations, such as the
Soccer World Cup when several
thousands of megawatts are used
in a flash. By the time a coal-fired
power plant boosts its operations,the soccer match would have long
been over.

High performance on demand:
From zero to maximum output
in electricity refiner seconds
In contrast to slow reacting thermal
power plants, pumped storage
power stations can generate electricity very rapidly. For instance atthe Wehr pumped storage power
station it only takes about 100
seconds to start a turbine fromstandstill to full output. Other, very
new pumped storage stations evenmake it in 20 seconds! As soon aselectricity consumption surges withthe end of the first half of the match,peak electricity is called in fromstations such as the Wehr underground power station. The sphericalvalves at the turbines are opened,
and water immediately flows downfrom the Hornberg reservoir, theupper storage lake one thousand
meters above sea-level, into theturbines.

640 meters below, the rushing water
impacts the massive blades of fourFrancis turbines arranged side byside in a huge underground powerhouse – twice as long as a soccer
field. The power station generates
almost a 1,000 megawatts undergenerator operations: in just under
90 seconds the output of a mediumsized nuclear power plant is thus
made available.

electrical grid for pumping. In thisway consumption peaks can beeffectively absorbed.

The Wehr pumped storage power
station is part of a system of fivepumped storage plants of Schluchseewerk AG, with 20 machinesets in all. This system is controlledfrom a central control center. The
Schluchseewerk turbines can besupplied from 14 storage resevoirs.
Thus, if needed, they can generatea maximum of 1,800 megawatts
within a very short time. In the
opposite direction, and in order to fill
the upper reservoir, they can absorb
a total of 1,548 megawatts from the

The pumped storage power stations
are not only the ideal peak electricity suppliers simply because they
supply a maximum of electricity
into the grid very quickly. Just as
important is the capacity to rapidly
decrease electricity production.

“Pumped storage is the only
way to store electrical energy
on a large scale”
explains Dr. Klaus Schneider of the
Schluchseewerk AG.

being supplied to the grid could
result in dangerous voltage overloads and frequency deviations.
They, in turn, could damage sensitive electrical equipment.
While thermal power plants cannot
shut down at short notice, hydroelectric power plants can run down
their electricity production to zerovery quickly. As soon as the teamsin the stadium run back onto thefield, the heavy spherical valvesclose, shutting off the flow of waterfrom Hornberg reservoir, so that
output is reduced to actual consumption. The second half begins –the electricity grid is stable.

Timing is vital: Surplus energy
becomes peak electricity
After flowing through the underground turbines, the water fromthe Hornberg reservoir now flows

September 2006 I 14 I HyPowerthrough an underground tunnel into
the lower reservoir – which was
created by a dam on the Wehr ariver upstream of the town of Wehr.
As soon as the soccer gameresumes and the fans again concentrate on what is happening on
the field, the water is pumped backto the upper storage lake.

“Our pumps can pump 144
cubic meters of water a second
uphill over 640 meters”
explains Alexander Schechner ofVoith Siemens Hydro, the hydropower specialist. At first glance thismight seem a contradiction in terms.
After all, the energy needed forpumping uphill is inevitably greaterthan the electrical energy which canbe subsequently generated with thiswater. Some 1.3 kilowatt hours ofelectricity are needed to generate

one kilowatt hour. However, this dual
energy transformation of electricity
into potential energy and back still
makes sense from technical andeconomic standpoints.
“The interesting aspect is that whenthe machines are in pump mode,
electricity is available at low cost in
the grid. This is because otherplants, such as coal-fired and nuclear base load plants, must always
run. That is what makes pumped
storage economical”. As a rule,
pumped storage power stations
make use of base load periods
when an excess of energy in thegrid makes electricity very cheap –for instance, at night – to fill their
upper storage reservoirs. These
storage lakes filled by using cheapnight-time electricity are thenreleased through the turbines during peak load periods to generate
expensive peak power.

A great one-two pass:
Pumped storage power
stations and wind energy
The day and night rhythm of generating and pumping operations is by
no means the only operating schedule. Demand alone dictates theoperating regime for the machinery.
Even rapid operating mode changes
are no problem for the Schluchseewerke power stations and their
Voith Siemens Hydro machines.
“When, for instance, a thunderstorm
suddenly occurs and people areswitching on lights and needing
electricity during a pumping cycle,
the pumps can be shut down withina very short period and the power
station can immediately return togenerating operation”, explains
Alexander Schechner.

The fact that pumped storage power
stations can quickly react to shortages and surpluses in the electricity
grid makes them ideal stabilizers. In
2004, they switched over 16,000
times between the different operating modes. The capacity of pumped
storage power stations to supply
both – energy as an electricity
producer in the under generating
mode, and “negative” energy as aconsumer in the pumping mode –makes them highly suited for integrating the growing number ofhighly fluctuating energy producers,
such as wind energy plants.
If there is a surplus of electricity,
the pumped storage basins can be
filled. And if there is a need, thenenergy is immediately on call: likea “water battery” in a sense.

Soccer World Cup: Electricity
consumption tells of victoryor defeatIn the dispatching centers, engineers know precisely when it is time
to fill up or drain their “water batteries”. Even during the World Cup.
Without knowing the result, they cantell from the electricity consumption
curves if the German team has won
or not. If they lost, electricity consumption immediately soars at thegame‘s end. If they won, the peakloads only come some 15 minutes
later – after all, cheering does takesome time. But there is one thing
the fans can rely on: the right temperature for the drinks is always
on hand, no matter when they aretaken out of the fridge.

Pumped storage – the electricity refiner
The rising demand for peaking power is creating a completely
new market value, which is also increasing the attractivenessof pumped storage power stations. This is particularly true at
power stations where storage lakes already exist. As a result,
there is no need for the otherwise often lengthy approval procedures and costly storage lake construction.

In addition, existing high-voltage
power lines can be used with minor
modifications, negating the needfor new transmission lines andnegative impacts on the surrounding environment. Construction of
a power tunnel between the upperand lower reservoirs requires muchless civil work than constructing acomplete new hydro scheme.
In one sense, pumped storage
power stations are electricity “refiners”: They make use of low-pricesurplus electricity when consumption in the grid is low and use it topump water from the lower into
the upper storage reservoir. Later,
this water is then used to generatevaluable peak electricity when therequirement for electricity is sudden
and high.

The objectives for new pumped
storage plants, embedded inalready existing water storage
structures can generally be defined
as follows:䡲 Power boost
䡲 Rolling pumped storage䡲 Additional control energy䡲 Voltage control
䡲 Frequency control
䡲 Reactive power control䡲 Raising of secondary control
and minute reserve(possibly also primary control)

Pumped storage power stations

Primary control

Secondary control

Primary control represents thereserve for momentary restorationof the power balance and stabilization of a continuous frequency
following a malfunction. It, therefore,takes top priority. Up to 3,000 MW
must be provided within 30 seconds
or less. Pumped storage power
stations are only suitable for primarycontrol mode when designed for theso-called “hydraulic short circuit”
operating mode, while connectedto the grid.

In the case of variations lasting
longer, the primary control isreplaced by secondary control after
30 seconds. It is used to control thethen remaining frequency deviation.
As a result, the primary reserve isagain released and is once more
completely available for further gridstabilization. Storage and pumped
storage power stations are the main
suppliers for secondary control
purposes; they do not need to beconnected to the grid.

stabilize electricity grid

As the generation and consumptionof electrical energy is not absolutely
synchronous and there is always asurplus or lack of electricity in thegrid, the provision of control power
is another major constituent toguarantee the safe operation oftransmission grids; something thatcan be very well fulfilled withpumped storage power stations.
A distinction is made between
primary control, secondary control
and minute reserve, depending on
the length of time of the variations –with the reaction speed being themost important quality feature.

Alternatives exist: Pump-turbines
can consist of two machines, pumpand turbine. With these two separate
machines, the pump output can berouted directly to the turbine byvalves with only a small energy loss
being added to keep the pump in
operation. If the need to absorb
energy occurs, the pump is switchedto reservoir consumption absorbing
lots of energy while the turbine isshut down. If power is needed, theupper reservoir water is routed tothe turbine. Another option withreversible pump-turbines could bethat turbine operation mode would
be that of a synchronous machinecondensing in air, while the othermode would be spinning or pumping.

Minute reserve

The minute reserve is drawn on
when grid overloading is in excess
of 15 minutes. Pumped storage
power stations are very well suitedfor the minute reserve. To control
grid variations, the power stations
must be in a position to change
their power with a gradient of atleast 2% per minute of their maximum power. The provision ofa minute reserve must correspondto the variation in the minute range.
To this end, pumped storage power
stations are extremely well suited,
due to their broad power range.

The classic concept:

Separate pumps and turbines

in Austria

in Kops II

Voith Siemens Hydro is supplying
equipment for two new and innovative pumped storage power stations
in Austria: Kops II in Vorarlberg
and Kaprun’s Limberg II plant in
the Salzburg area. In both cases,
new power plants are being added
to existing stations and will use theexisting storage reservoirs.
The projects are, however, radicallydifferent from one another in termsof hydraulic machinery: Kops II isof the fomerly “classic” design
equipped with separate turbine andpump sets, consisting of a Peltonturbine and motor-generator, ahydraulic torque converter (HTC)with gear coupling, and a multistage storage pump, while in
Limberg II each motor-generator
is directly linked with a reversible
pump-turbine (see schematicalcomparison).

The classic concept with separate
machines is being used in theKops II plant due to the need for
extremely rapid switching time
between turbine and pump operation. This is because the Peltonturbine can be opened and closed
very quickly and the storage pump
– as a result of the hydraulic torqueconverter’s effect – can be connected to or separated from theshaft system within seconds.

The primary control capacity fromrealization of the “hydraulic shortcircuit” is an additional benefit that
may very well match the additional
investment for equipment and civil
construction. And so is the conservation of water that is recycled
directly from the pump in the turbine.

September 2006 I 14 I HyPowerAs two separate hydraulic machines,
the rotational direction of the motorgenerator can be the same in both
operational modes. This solution
may create considerable commercial value added to today’s utility
operators.

Since pump efficiency drops quite
rapidly when operation deviatesfrom the optimum design parameters, but the turbine under partial
load will still provide remarkableefficiencies, it might still be economical to operate the pump at full
capacity using the low electricalsurplus power in the grid, and to
generate the power that the motor
generator lacks, by deflecting someof the pump water flow in the turbine connected on the same shaft.

Another enormous hydraulic shortcircuit benefit has recently been
added: it is the quick response to
the grid due to machine’s constantsynchronization with the grid at all
times.

Voith Siemens Hydro has been
compiling references for HTC sincethe 1950s. The Kops II power station operator Vorarlberger Illwerke(VIW) was in fact the first customer
to receive a Voith HTC back then.

as a benefit, to help quick pump
operation changes. Characteristicof reversible pump-tubines is thelonger switch-over time from turbine
to pump operation and vice versa.
This is down to the air being used to
expel the water in the turbine for restarting under pump operations, as
the start-up equipment for the motor
would not be in a position to do sowith water. The rotational direction
must also be changed, as thisreversible machine operates in both,pump and turbine mode.

Compact dimensions and

In Limberg II the solution of a reversible pump-turbine has proven to be
the most efficient one: in comparison
with Kops II, the Limberg II regulation requirements are not as sophisticated and complex; also, the morecompact design of the machine andconsequently civil construction,
results in lower investments. In bothcases, the selected design for the
pumped storage arrangements waschosen as an optimum technicalsolution that – in the context of grid
regulation demands of each plant –results in the best possible returnfor the operating utility.

In Kops II, three machine sets witha combined output of 450 MW will
be built for 820 m head. The HTC
and storage pumps supplied byVoith Siemens Hydro as well as thespherical valves are the key components in the supply contract.
Since the HTC has a coupled pumprotor fixed to the generator shaft
and a coupled turbine runner fixed
to the pump shaft, it ensures apump run-up time of only around
10 seconds. At the same time as
the converter is filled with water, theturbine runner and with it the pump
are accelerated to the rated speed
and – with both runners at the same
speed – a gear coupling is activated
to connect the pump to the unit
shaft. Simultaneously the converter
is being emptied.

Hydro power enhances India’senergy security and is ideal for
meeting peak demand. Less than
one fourth of the vast 150,000 MW
hydro power potential has beentapped so far in India.

At present, Voith Siemens Hydrois also actively involved in the construction of the 450 MW Bagliharhydroelectric project for Jammu
and Kashmir Power Development
Corporation.

In fact, the share of hydro generation in India has gradually declined
over the past 25 years. India’s goal
is to have 40 % of its power generation from hydro power; currently it isabout 25 %.

Voith Siemens Hydro Power
Generation, along with its Indianbusiness unit, founded in July 2002
in New Delhi, is committed to thecontinued development of hydropower in India.

Historically, Voith Siemens Hydro
has been active in India’s hydropower sector. In 1911, the company
supplied four generators and auxiliaries for the Khopoli Power Houseof Tata Hydro-Electric Power Supply.
This power house is still in operation, reflecting Voith Siemens
Hydro’s dedication to quality andtechnology.

Modernization contract for Mequinenza in Spain
Voith Siemens Hydro’s scope of supply in this contract comprises
the modernization and upgrading of four vertical Francis turbines(4.3 m runner diameter) with a rated capacity of 81 MW each,four 90 MVA generators (8.3 m rotor diameter) and four high voltage transformers of 95 MVA.

In order to maximize the future plantrevenue, Voith Siemens Hydro, in
close cooperation with the owner,
Spanish Endesa, developed atechno-economically optimized
hydraulic design that will ensure
the best mix of energy production,
storage capability and installedcapacity. Through the modernizationof the Mequinenza hydro power
plant, the maximum output will be
increased by 30 % to 324 MW at
a rated head of 47 m and by 20 %to 384 MW at a maximum head of
53 m.

Promising future for ocean energy
Another important step in the development of ocean wave
energy for commercial application has been achieved by Voith
Siemens Hydro and its Scotland-based subsidiary Wavegen:
Two new wave energy projects are on the way.

British RWE-branch npower renewables and Wavegen haveentered into an agreement to build
a 3 MW wave power plant in theouter Hebridian Islands of Lewis
and Harris.
The technology used in the newplant would be based on Wavegen’s
Limpet plant on the Island of Islay,
which is currently the world’s only
commercially operated wave power
plant. For several years, it has been
supplying electricity to the grid thatpowers private households on theisland.
In 2000, the plant was installedwith a capacity of 500 kW.

This new project would be integrated into a new breakwater, which
would considerably reduce the costof civil construction and, at thesame time, provide 1,500 households with power and build a new
harbor for the local infrastructure.
Possibilities for wave energy havealso been opened up in continental
Europe: Here, Voith Siemens Hydro,
in cooperation with EnBW of Germany and the government of theFederal State of Lower Saxony,
Germany, intends to develop andconstruct the country’s first wave
power station.

The envisaged nominal capacity ofGermany’s first near-shore power
plant is planned to be 250 kW,
resulting in annual electricity generation of 400 MWh – sufficient for
120 households.

Hydro power and greenhouse gas emissions
The hydro sector continues to face accusations that hydro power
contributes to global warming. Cumulatively, the message is that
freshwater reservoirs are part of the climate-change problem,
rather than part of the solution, especially in warmer climates
where the carbon cycle is more active.

Development of guidelineswithin IPCC

At its meeting in Mauritius in April
2006, a task force of the Intergovernmental Panel on Climate
Change (IPCC) put forward its draft
2006 Guidelines for National Greenhouse Gas Inventories for internal
adoption.

28

The draft included a section on
flooded lands, allocating default
emission factors of carbon dioxide(CO2) for all new reservoirs. Different factors were proposed according to climate type. In addition,
the intention was made clear totake the same approach for methane (CH4) emissions from reservoirs.

September 2006 I 14 I HyPower

GUEST ARTICLE

On behalf of its members, the International Hydropower Association(IHA) wrote to the IPCC Executive
and also to various government
contacts to express concern about
this development. IHA’s position
was that the science on which IPCC
had been advised was based ongross emissions collected by the‘flux’ method on a small sample ofreservoirs.

It was argued that the observed
gross emissions did not subtract
emissions that would have occurred
naturally within the carbon cycle.
While there was no consensus as tothe calculation of any anthropogenic
contribution, there was certainty
that water in the drainage basin wasa major vector in the natural carbon
cycle and that significant emissions
would occur irrespective of the presence of a man-made reservoir.
Therefore, the IPCC advisors had
substantially overestimated thecontribution of greenhouse gas(GHG) resulting from freshwater
reservoirs.
During the IPCC meeting, several
country representatives argued
against the ‘flux’ method presented
in the draft. Ultimately, anotherapproach, the ‘stock’ method, wasput in place of the original text
(which was moved to an appendix).
The stock method requires the ‘total
submerged living biomass carbon
stock’ to be assumed to be emitted
as CO2. The section includes an
acknowledgement that the emissions are progressive (multi-year)and “may lead to overestimates”.
No default emission factors wererecommended, but an equation wasgiven to establish a value based on
the type of inundated vegetation
cover. The IPCC Guidelines werethen adopted before the close of theMauritius meeting.

September 2006 I 14 I HyPower

Proposal of IPCC Guidelines
to UNFCCC

Following the Mauritius meeting,
IPCC presented its 2006 Guidelines
to the Subsidiary Body for Scientificand Technological Advice of the UN
Framework Convention on Climate
Change (UNFCCC) in Bonn, May
2006. During this meeting, several
governments expressed reservations about the new Guidelines.
IHA was represented in Bonn andalso delivered a formal note ofconcern. IHA urged extreme caution
in the use of the guidelines.
The outcome of the discussions
appears to be that UNFCCC will not
be requiring its Designated National
Authorities to put the new guidelines
into practice.
IHA proposed that parties must takethis opportunity to find a methodthat analyses freshwater reservoirs
in terms of their net impact on thewhole drainage system, according
to a life-cycle approach. The methodneeds to measure not only outputsof GHG, but also carbon inputs,
transport and accumulation in thedrainage basin. Clearly the current‘stock’ and ‘flux’ approaches do not
fully address this. IPCC appears to
be looking to make a new start on
this subject, with a wider community
than in the past. At the same time,
the hydro sector must engage inthis issue with more commitment.

GUEST ARTICLE

Hydro in the Clean
Development Mechanism

In parallel with the afore-mentioned,
IHA became aware that the Executive Board of UNFCCC’s Clean
Development Mechanism (CDM)
had introduced new criteria forhydro project applications.
T criteria are based on thresholds
in terms of power density (W/m2),
as follows:i. Projects with power densities(installed power generation
capacity divided by the flooded
surface area) less than or equal
to 4 W/m2 are excluded;
ii. Projects with power densities
greater than 4 W/m2 but lessthan or equal to 10 W/m2 canbe eligible, but with an emission
penalty of 90 g CO2eq/kWh;iii. Projects with power densities
greater than 10 W/m2 can beeligible, without penalty.
In response to this, IHA wrote to
the CDM Executive to argue thatthe criteria would inappropriately
exclude the majority of hydro power
projects.

30

IHA research indicated that a power
density of 4 W/m2 was well above
the international average for hydropower, while the vast majority of thegross GHG emissions from reservoirs were significantly lower than
90 g CO2eq/kWh.
Again, IHA argued that gross emissions did not subtract emissions
that would have occurred naturally,
and that emissions would haveoccurred with or without the inclusion of a hydro power scheme.
The conclusion being, that the CDM
criteria grossly overestimated thecontribution of greenhouse gas
resulting from hydro generation.
An example was presented in relation to testing on a scheme in Norway that would technically fall into
the CDM category ‘ii’. It was demonstrated that the proposed CDM
allocation overestimated the measured gross emissions by a factorof 15.

Clearly, the CDM error is evenhigher as a significant proportionof the measured gross emissions
would have occurred naturally.
For the CDM Board Meeting in July
2006, IHA requested consideration
be given to its opinion that the new
CDM criteria places hydro power
projects at an unfair disadvantage
in terms of eligibility within the
Clean Development Mechanism.
IHA has also offered to provide
further input on the impracticalityof the criteria, regardless of thepower density thresholds.

his Internet homepage – that’s
when he’s not skydiving, bungeejumping, rafting or canyoning.
In early 2000 he travelled to Lake

Lake Powell owes its existence to
the Glen Canyon Dam. It was built
in the middle of the Colorado Riverto generate power to provide seven
US states and Mexico with waterfrom the lake. Ladybird Johnson
opened the Dam in 1966 and it took
17 years before Lake Powell, named
after explorer Major John Wesley
Powell (1834 - 1902), was completely
full. Lake Powell became an enormous reservoir with a coastline ofjust under 3,200 kilometers andalmost 100 side canyons. It boasts

are increasingly seeking adventure
and inspirational nature experiencesin their leisure hours.

appeal to tourists.

September 2006 I 14 I HyPowerESSAYIn Germany for instance, in the spa
town of Schluchsee in the Black
Forest, Schluchseewerke AG,
founded in 1928, built a 64-meterhigh dam near Seebrugg in cooperation with the Schluchsee power
plant group. The gravity dam prevents natural outflow from the original Schluchsee. Following completion of the dam, the water level was
30 meters higher, thereby creatinga reservoir with a capacity of 108
million cubic meters. When full,
the reservoir has a surface area of
514 hectares, making the Schluchsee the largest lake in the Black
Forest.
The towns surrounding the lake,
which in 2005 was awarded the titleof “Rambling Location of the Year”
at Europe’s largest tourism tradefair, the CMT in Stuttgart, are not
shy in promoting their best asset:“Whether sailing, surfing, rowing,
diving, swimming for relaxation or

Most importantly, the Schluchseeis extremely clean. According to
the German consumer protection
organization, Stiftung Warentest,
the Schluchsee has been one of
the cleanest swimming lakes inGermany for many years.” Motorboats are prohibited. But canoeing,
sailing, surfing, swimming anddiving in the reservoir are all
allowed.

At the beginning of 2000, Lake
