A portion of the stream of the Drin has found its way into the Boyana channel; the result has been a rise in the level of Lake Scutari and the inundation of the adjacent lowlands.
In the extreme south, beyond the basin of the Kalamas, the mountains of Suli and Olyzika form a separate group. The rivers, as a rule, flow from east to west; owing to the rapidity of their descent none are navigable except the Boyana and Arta in their lower courses.
The northern boundary of Albania underwent some alteration in consequence of the enlargement of Montenegro, sanctioned by the Berlin Treaty (July 13, 1878); owing to subsequent arrangements providing for the cession of Dulcigno to Montenegro (November 25, 1880) in exchange for the districts of Plava and Gusinye, restored to Turkey, the frontier-line (finally settled December 1884) now ascends the Boyana from its mouth to Lake Sass (Shas), thence passes northward, and crossing Lake Scutari separates the district of Kutch Kraina on the N.
A proposal to confine the Drin to its former course by means of a dyke, and to ease the downflow of the Boyana by a canal opening navigation to Lake Scutari, has long been considered by the Turkish authorities.
