NATURAL FEATURES
I am indebted to Mr A.H. Elton for some of the particulars of the geological and other features of the district:-
"At Clevedon a double range of hills, rising to some 300ft above the level of the sea, commences, extending northwards to Portishead and eastward to the defile of the Avon at Clifton. The latter range consists of mountain limestone, occasionally overlaid by beds of magnesian limestone of excellent quality, and much valued for building purposes. To the north of this range the limestone dips beneath the coal measures in consequence of a geological fault, and the super incumbent soil becomes deeper and of a more sandy nature, whilst masses of Pennant stone occasionally emerge on the surface. Coal has formerly been drawn from this side of the hill but the difficulty of preventing the influx of water into the works seems to have been the cause of their discontinuance. On the range of hills towards Portishead, about a quarter of a mile from Clevedon near the interesting ruins of Walton old church, there is an excellent spring of water, which loses itself in the sea.
The air of Clevedon is mild and salubrious. The myrtle
and other tender shrubs flourish in sheltered spots. The surrounding
countryside is very fertile and well wooded. the prevalent winds are
from the west and southwest, and coming over the Atlantic tend to
render the climate of the place more fresh and invigorating than
would otherwise be the case."
Dr. Frowd
states:-
"I consider this part of the country a
decidedly healthy one. The air, except in November, is dry the air
is generally speaking, mild; it is cold in March and May. The winds
most prevalent are from the southwest."
The
Land Yeo
A small stream called the Land Yeo runs through the
lower portion of the village into the Bristol Channel. The principal
spring, which supplies or used to supply it, rises about 7 miles
distant, at Barrow Rocks. Owing to the water of that spring having
been purchased by the Bristol Water Company some three years ago, it
was stated that the stream is diminished in volume being sometimes
nearly dry.
The Levels Land drainage
Upwards of
2,000 acres of which the parish consists is marsh or moor land. The
whole of the village lies low, at or slightly above the level of the
surrounding flat. The Commissioners of Sewers for the north division
of east Somerset have jurisdiction over the whole of the marsh land.
With reference to the powers and proceedings of the
Commissioners,
Mr John Cook, Farmer states: -
"With regard to the accumulation of filth they have
power, if they fall into the rhyne to order their removal. But they
have no power over the ditches unless the jury makes application to
have any particular ditches placed in commission, when they might
order such ditches to be cleansed.
The Land Yeo which runs
through the lower part of the town is a main outfall for the
neighbouring level, and is regularly cleansed four or five times a
year under the direction of the commissioners. There are also in the
lower part of the town many ditches communicating with the Land Yeo,
and which receive drainage from their banks. I believe there are
three or four ditches on this side of the Land Yeo, which do not
communicate with it.
The Cleansing of the Land Yeo consists
in the cutting and pulling out of the weeds and rushes, and then
cleaning out the mud from the bottom of the stream. It is not the
practice to throw out the mud more than once a year, but the weeds
and rushes are removed every time of cleansing. The work is
performed by the parties occupying the lands on each side of the
river, at their own expense. I have never known any of the other
ditches alluded to cleansed by order of the Commissioners of Sewers.
This is only done when the parties to whom the lands belong feel
inclined to throw out the mud, and which they use as manure. Any
ditch may be placed in commission by order of the Commissioners.
The level of the water in the rhyne ought to be regulated by
the Commissioners, but, with the exception of the flood hatch at the
mouth of the two outfalls, which there are in the parish, there are
no means of controlling the water. The object of these hatches is
rather to shut out the sea than to regulate the water in the rhyne.
I know parts of the parish where hatches formerly existed, which are
now without them. The great desideratum would be to have water in
the summer, and this a proper number of hatches would effect. In
parts remote from the river there is in the dry weather a want of
water for the cattle. Juries report to the Commissioners when
anything requires to be done."
Mr John Riddle [John
Kiddle] states:-
"The whole of the village lies low, but
I have no doubt that the Land Yeo has a good fall, so I don't think
there could be any difficulty in draining this parish. I have never
seen the main street of the village flooded. Every year more or less
of the moor is flooded. I have seen within the last 9 years perhaps
50 acres under water. In winter the water in the ditches generally
along the village will be 18 inches to 2feet, and even 3 feet below
the surface level, and more still below the level of the street. The
water of the ditches on Nailsea Moor will be near the surface at
such times. This part is generally flooded after heavy rains. I have
seen it under water. The floods are caused in my opinion by the want
of sufficient outlets to the sea. Many complaints have been made to
the Commissioners of the Sewers on the subject: some having too much
water and others not enough."
It was observed that the
ditches on Nailsea Moor have no communication whatever to the Land
Yeo, but communicate with the Middle Yeo & the Blind Yeo. And it
appears probable, as was stated in the course of the examination,
that the floods when they occur are frequently attributable to the
circumstance of rain falling at the time of high water, more
especially at spring tides, when the outlets are closed. Mr Riddle
explained that the flood he had spoken of in the course of his
evidence in chief was caused by a very high tide washing away part
of the sea wall, and running up the level to Nailsea. It was a flood
of salt water, which, however, forced back the land water in the
interior of the flat.
On the other hand, Mr Richard
Glanville, a farmer, stated with regard to the inundation in
question, (which occurred in February 1834) that it was caused by
the tide overflowing the whole of the seawall, and not by its
breaking down any part of it. He added:-
"It occurred
during a dead calm, otherwise the whole of the flat would have been
laid under water. The sea, I should say, rose as much as 4 inches
above the wall"
The Tide
The rise of tide
varies from 22 to 36 feet. Very high spring tides, it appears, would
reach four or five feet above the level of the flat. There is a mill
at Tickenham, about three miles up the river, which it appears,
affects the continuous flow of water. Complaints had been made of
the damming up of this water by this mill injuring the land behind
it.
Mr A.H.Elton said that he considered the drainage of
this part of the county to be very much mismanaged, and that the
land suffered in consequence he added:-
"About two
years ago, Mr Gordon, the owner of a large tract of country in the
level, brought forward a plan for the improvement of the drainage of
the whole land. He proposed to widen and deepen the Middle Yeo, and
in this manner to rid the level of the water, and to enable the
proprietors to drain their own lands. The cost of these works from
Nailsea to the outfall was estimated at about 4,000 pounds, and it
was supposed that about 1,300 acres would be benefited by them, and
acquire an additional value yearly of nearly one pound per acre.
However the plan fell to the ground for want of support, and I
brought it forward as an instance that there is a general feeling
abroad that some improvement is required. I do not myself altogether
approve of the plan. Mr Gordon, at a meeting of the Court of Sewers
in October last, again brought the subject under notice of the
commissioners. I sent Sir Charles Elton's agent to urge upon them
the expediency of their directing their attention to the subject.
The Commissioners then indicated they would give due consideration
to any plan for improving the drainage of the level, but they
declined to take the initiative in any plan themselves. The powers
of the Commissioners are extensive, and in taking the course they
did I do not think they acted up to the spirit of their duties,
which I consider are to improve to the utmost the drainage of the
flat."
