The Blue Spring is a karst spring in Erl in the Lower Inn Valley and the oldest natural monument in Tyrol .
description
The source lies at a height of 471 m above sea level. A. around 300 m southeast of the Erler Passion Playhouse. It feeds a spring pond that gave it its name with its clear, deep blue color. The sandy ground is covered with candelabrum algae . The pond is surrounded by a grove of horse chestnut , beech , oak , ash , linden and birch trees. The spring, pond and group of trees were the first to be declared a natural monument in Tyrol in 1926. The water flows over Mühlgrabenbach and Trockenbach to the Inn after about one kilometer .
Hydrology
Since 1992 there has been a spring measuring point (number 395434) of the Hydrographic Service Tyrol at the Blauer Quelle. Typically for a karst spring, the water flow increases rapidly when it rains. The mean spring discharge is 751 l / s (series 1992–2010), the minimum 291 l / s (measured on January 9, 1999), the maximum 2132 l / s (July 11, 2005). In contrast, the slight fluctuation in the water temperature of only 0.2 ° C is noticeable; it is almost constant at 8.1 ° C. The conductivity also varies only relatively slightly between 516 and 596 μS / cm with an average value of 581 μS / cm. The slight fluctuation in temperature and conductivity indicates a high proportion of deep karst water.
