Poole, Dorset 
This huge inlet of the sea measures some 7 miles from north to south and about half that from east to west but, so irregular are the shores of the inlet that they extend over a hundred miles.
If the drainage system of county of Dorset is subdued and not reknowned for any large bodies 
of water then Poole Harbour by its sheer extent and the intricacy of its shore more than 
makes up for the ommission. 
At the seaward end, the harbour is almost enclosed save for a narrow channel crossed by 
a car ferry by Sandbanks and the Studland peninsula. This 
large and nearly enclosed body of calm water which is subject to the double tides which 
prevail in Bournemouth Bay has been dubbed The Lake of 
Dorset.
It is to this peculiar phenomemon of the double tide - for it is subjected to two tides 
every twelve hours with about three hours between successive high water - that the harbour 
owes much of its beauty. It retains much of its load of water and does not suffer the 
low tides which expose vast expanses of barren mudflats in other estuaries and harbours.

ISLANDS IN POOLE HARBOUR
Adding to the interest and charm of the harbour with its convoluted shore are its many 
islands and Brownsea near its mouth, the largest, most 
conspicious and best-known of these, deserves seperate 
consideration.
Among the larger islands in the harbour (Brownsea, the largest,
being mentioned separately) are Round Island, Long Island, 
Green Island 
and Furzey Island.

In June 2002, it was announced that sole use of 
Green Island 
which is in private hands 
could be obtained on payment of a rent of £ 1,000 annually to the owners.

THE SURROUNDING AREA
The area which surrounds the island and mudbank speckled waters of the harbour to the 
south and west is comaratively unspoilt and has been designated an 
Area of Outstanding Natural Beauty.
To the east of the harbour mouth the sandy spit known as 
Sandbanks is, at its narrowest, only a few hundred metres wide although it broadens 
out towards its extremity. It is populated with presitious houses and apartments and 
the clean sandy beaches are a mass of colour during the holiday season.
But minutes' ride on the ferry across the harbour mouth brings the wilder beauties of 
heath, marsh, sand-dunes and qieter beaches as one disembarks on the 
Studland peninsula owned by the National Trust. Inland, as the 
widening strip of land joins the Purbeck hills lies the pretty 
village of Studland itself which might be missed amongst 
its many trees.
On the western shores of the harbour, Russell Quay has a large heronry and Ower has an 
interesting pond much frequented by seagulls. The picturesque village of Arne boasts a 
tiny church as its only amenity but is also host to the Arne RSPB reserve. Wyche once 
served as port to the villagers of Corfe and the masters of the 
castle there. Now it 
is but a few houses. Perhaps its greatest claim to fame (at least within the local area) 
is the oil which is surrendered 
by the rocks deep beneath trunk and turf and the 
controversey which the discovery of the black gold sparked.
The heathlands which are found here on the southern and western 
shores of the harbour such as on the Studland peninsula, at 
Agglestone and Arne make an ideal habitat for our reptiles. 
So much so that all six reptiles native to the British Isles 
are found there. Many of these heathlands have been designated as 
Sites of Special Scientific Interest (SSI's).
