During
the work starved pre-war years of the early 1930's there was
a proposal put forward by John Jeffrey (a Bo'ness hotel owner)
and Mathew Steel to dam the Forth at Queensferry. Mathew Steele
was the architect responsible for the design of the Hippodrome
Cinema, Masonic Lodge and No. 11 South Street (Now S&J Studios)
was designed by Mathew Steel for John Paris.
At the time this would have: - employed thousands
of labourers; given Bo'ness Harbour a new lease of life, since
shipping could leave and enter at any time; encouraged shipbuilding
at Grangemouth; created a semi-tidal waterway in Britain,
larger than Loch Lomond, and which could rival any Swiss lake
for amenities; produced hydro-electric power for use in all
Forth Valley towns; be used as a landing facility for sea-planes
which were being considered for commercial flights at that
time. Alas when war broke out all thoughts
of this proposal were forgotten.
Today
things are entirely different and this idea is utterly absurd,
yet is it?
Anyone
commuting out of Edinburgh by car, and particularly those needing
to cross the Forth will be all too aware of the problems with
congestion and high winds effecting traffic crossing the Forth
Road Bridge. This also has a knock on effect on the Kincardine
Bridge, which has enormous traffic problems every time the Forth
Road Bridge is closed, or partially closed, because of accidents,
weather or ever increasingly due to bridge works.
To
many the idea of a dam across the Forth is fanciful to say the
least, but many of the benefits that Jeffrey and Steel anticipated
are even more appropriate today.
Imagine a tidal dam across the Forth at Queensferry
topped with six lanes available for traffic, which would only
require a bridge to have a central span to give sufficient height
and breadth to let through shipping. Weather would therefore
have little effected, and the artificial semi-tidal loch created
would have a tremendously positive effect on the tourist trade
for all the coastal towns on the Forth, from South Queensferry
to Stirling; breathing new life into Bo'ness, Alloa, Charlestown,
Rosyth, Blackness to name less than half. Recreational watersports
such as sailing, canoeing, wind surfing and boating would all
boom since on semi-tidal waters they would be safer and accessible
at all times; over-wintering boats would also be much less of
a problem and less costly. As an added advantage hydroelectric
power could be fed to the national grid and produce some revenue.
Since the river would still be semi-tidal there would be little
detrimental effect to the mud flats, bird and sealife populations.
For the most part the dam could be in-filled with compacted
ash or shale, from the hideous looking red shale bings seen
from both the M8 and M9.
Neither
is the project too ambitious; the Grand Coulee Dam on the Columbia
River, Washington State, USA has a crest length of 4,173ft, is
550ft high and the volume of concrete poured was a massive 8,092,000
m3.
Too
ambitious? At
Cridling Stubbs, N.Yorkshire the National Power's Gale Common
Tailing Dam has put in place 15,000,000 m3 of
compacted ash, or almost twice that of the Grand Coulee
Dam aforementioned. |
