Rh between Gothenburg and the Scaw the greatest depth is between 33 and 55 fathoms. The greatest part of the southern half of the Cattegat has a depth of less than 30 fathoms. The depth of the Sound generally is even less than 12 fathoms. The whole southern part of the Baltic between Sweden and Germany is very shallow. West of Bornholm the depth nowhere reaches 30 fathoms. East of Bornholm the sea is somewhat deeper, and a small area of a depth of 50 to 60 fathoms is found a little east of that island. The whole of that part of the Baltic which lies between Sweden and Russia is divided into two separate basins by a submarine bank. From the southern extremity of Gotland (Hoburg) there extends a nearly uninterrupted bank to the south-west as far as the Prussian coast. The depth on this bank nowhere reaches 30 fathoms. The shallowest parts are Hoburg Bank south of Gotland, Mittel Bank south-east of Öland, and Stolpe Bank off the Prussian coast. Between Fårö off the north coast of Gotland and the Gottska Sandö there extends a similar bank, which continues with a somewhat greater depth of about 30 fathoms as far north as Stockholm. The deepest part of the Baltic between these banks is situated in the north part between Landsort and the Gottska Sandö, the maximum depth being about 160 fathoms. Ålands Haf, the channel between the Swedish coast and the Åland Islands, is tolerably deep (100 to 160 fathoms).

The Gulf of Bothnia is divided into two basins by the channel of Qvarken; the southern is the deeper (about 50 fathoms), and the depth increases towards the north-west, where, over a small area off the island of Ulfö near the Swedish coast, it reaches 160 fathoms. The channel of Qvarken is very shallow (8 to 16 fathoms). The basin on the north side is also shallow. Only over a small area off Bjurö Cape does the depth exceed 160 fathoms.
