The Ilz is a relatively small mountain stream and has a blue-ish color while the Inn is a fairly large river flowing in from Salzburg, Austria at the top. The Inn River has more water flow than the Danube, yet flowing away from the city the three combined rivers are called Danube. This photo is taken from the fortress (now a city museum) on top of the Ilzstadt cliff above the city.
HDR. It was the only way to bring out the colors of the river.
