Ennis

Ennis, a river of Austria, rises at the northern base of a branch of the Noric Alps in the crownland of Salzburg, 12 miles S. of Radstadt, and flows 190 miles (only the last 20 navigable) in a general northerly direction, till it joins the Danube a few miles below Linz. Its chief affluents are the Salza and the Steier. From ancient times the Ennis has formed the boundary between Upper Austria (Ober der Ennis) and Lower Austria (Unter der Ennis). Having mostly a rapid fall, it is chiefly important from the valuable water-power which it supplies.
